Out of the box, the Google Chromecast connects to your home network via its integrated 2.4GHz Wi-Fi circuitry. But what use is this if the TV you are using it with is in a lounge area furthest away from your home network’s router. And the situation is made worse because you are dealing with a double-brick wall between what was the existing house and the newly-built extension. This is while the TV’s circuitry and chassis materials effectively attenuate the radio signals coming from the front. You end up with heaps of buffering because the Wi-Fi wireless signal is very poor.

You might try a cheap wireless range extender but find that you are taking it back to the store because it isn’t really effective and is a lot more difficult to deal with.

But Google has answered your need by providing an adaptor accessory that effectively gives it an Ethernet port which opens up some paths to improve the situation. This means that you could take advantage of the Ethernet infrastructure if you wired your house for Ethernet, or could use a HomePlug AV500 or HomePlug AV2 powerline-network kit to effectively provide a wired link between your home network’s router and the Chromecast-enabled TV. Even using a wireless-Ethernet client bridge that is positioned for best reception or supporting newer Wi-Fi technologies can work wonders with this device.

This adaptor is effectively a power supply for the Chromecast along with a USB-connected Ethernet network adaptor and connects to the Chromecast dongle via its microUSB port.  As far as I know, the installation involved for this device would simply be a “plug-and-play” affair.  But, if you are using HomePlug powerline networking, I would recommend a HomePlug adaptor with integrated power outlet to save on power outlets or a HomePlug adaptor with integrated Ethernet switch so you can allow the PS3 or Blu-Ray player to take advantage of the same wired backbone.

It didn’t take long for Google to sell out of this device in the USA so if the link says “out of stock”, check back later. This could mean that they would have to ramp up the number of units being built and reckon that it is tome to release it in to other markets.

As well, anyone who is designing a network media receiver of the kind that directly plugs in to a TV’s HDMI socket and connects via Wi-Fi wireless could make sure there is a way to connect an Ethernet adaptor to these devices and such an adaptor is available.

Affordable long-run HDMI via Cat5 cable becomes a reality

My Comments

There are the home and small-business environments where you may want to have your AV source and control equipment away from the flatscreen TV or projector but want to see the high-resolution display. Such applications range from the home theatre through to a video projector set up in a bar to show sports events to a church using two video projectors to show the song lyrics, prayer requests and the like during service to its large congregation.

This has been made easier with HDBaseT which uses the Cat5 Ethernet cable to transmit HDMI AV up to 4K UHDTV along with power, 100BaseT Ethernet and USB over a run of up to 100 metres (328 feet) per inter-equipment “hop”. Then a single path between source and final endpoint could have 8 “hops”. This could cater for setups with a single wire passing a few “digital power amplifiers” positioned close to speaker setups as it heads towards a display or projector in order to serve a room’s AV requirements.

But this concept has been put out of reach of most small-business, non-profit and home users because this typically required the purchase of at expensive HDBaseT adaptors for each end of the cheap Cat5 cable run.

Now the standards body who are behind the HDBaseT standard are encouraging manufacturers to integrate the connectivity in to their equipment. When a customer purchases a display, matrix switcher, AV receiver or other equipment that has this connectivity, they reduce the need to buy another HDBaseT adaptor. This can reduce the cost required to provide another display or projector in that bar or restaurant.

Of course, the article cited a home theatre receiver and a single-wire TV display as a prototype along with a few video projectors having this technology.

The technology is also able to lead to the implementation of “one-wire” display equipment that will typically be confined to display panels. This avoids the need to run mains wiring to the display’s location which could reduce the material cost and safety issues associated with these installations.

For this technology to work properly, the display and other equipment must support standard HDMI-CEC control signals or other common industry standards for controlling the devices to allow a true mix of vendors through an installation’s life. Similarly, when this technology gets underway with integration in devices, it should then be feasible to see it available in reasonably-priced projectors.

What I like about this for smaller organisations is the concept of a standard leading to integrated video setups being available to suit the premises better at a cost that is more reasonable to this user base.

Feature Article–Wiring a house for Ethernet (Update)

Originally Posted on HomeNetworking01.info: 17 July 2010

Introduction

There may be a question that may come up when you build your new home or do renovations on an existing home. This question is whether to wire you premises for Ethernet or not and how to go about it?

What is involved when you wire for Ethernet

When you wire a house for Ethernet, you are providing a high-speed data backbone for your premises. This is achieved by laying Category 5 or Category 6 wiring from most rooms to a central location where there is a “switch” that moves data around the network at the appropriate speeds for the network devices.

The reason that it makes sense to consider the home-network issue, especially wired-in Ethernet, is because an increasing number of households are using two or more computers. Infact, there is an increasing trend for households to have more computers than TV sets. As well, computers can and have now become entertainment centres for bedrooms and other small areas thanks to optical-disc drives, sound-card setups and radio and TV-tuner kits that install in or connect to PCs. There is also an increasing common practice to copy CDs to the computer’s hard drive so that these computers double as personal jukeboxes, which is an asset with small areas. This means that there is a desire to have access to resources like the Internet and printers from all the computers that are in the house.

Similarly, there is an increasing number of consumer entertainment devices that can connect to the home network, primarily for access to online content or content that is held somewhere on that network. Most of these devices, such as Blu-Ray players and smart TVs, are using Ethernet as a baseline connection method with Wi-Fi, whether integrated or as an add-on module, as an alternative connection method. As well, a games console is now considered “well-bred” if it has a network connectivity option, with the two most-desireable consoles – the Sony PlayStation 3 and the Microsoft XBox 360 – having Ethernet connectivity at least. This means that these consoles can be integrated in online gaming scenarios as well as having access to online or network-hosted entertainment material.

Using “no-new-wires” methods as baseline networks

If you have networked your computer equipment by using a “no-new-wires” method like wireless or HomePlug powerline; you may be dealing with a network that isn’t working at its best. This is because the “no-new-wires” technologies work on having the “no-new-wires” segment’s bandwidth shared by all the devices that connect to the segment. It is exemplified by poor response time during a network multiplayer game hosted across the “no-new-wires” segment or slow transfer speed whenever a file is being transferred between two nodes on the same segment.

Typically, when you implement a “no-new-wires” network, you would use a broadband router that connects to an Ethernet segment and the “no-new-wires” segment on the LAN side, like one of the many wireless Internet gateway devices. Also, if you decide to add on extra network devices that don’t have integrated connectivity for the “no-new-wires” technology, you would have to buy extra network bridges so these devices can work as part of the network.The possibility of high-speed Ethernet being available for home-computer users is made real through high-performance Ethernet network-connectivity devices being made affordable and ubiquitous for most users.

As well, the switches that are required as part of an Ethernet network are now available at very cheap prices. This all ends up with the Category 5 Ethernet medium being considered as a lowest-common-denominator for network connectivity.

Why wire a house for Ethernet?

You will benefit from the high data throughput that Ethernet provides especially now that 1 Gigabit/ second is now becoming the norm for these setups due to affordable Gigabit Ethernet switches. This will benefit applications like Internet gaming, network media streaming such as Internet radio and video-on-demand; as well as graphics-rich printing.

You also gain the advantage of reliable network behaviour because you are not regularly sharing data transports that are prone to interference. This is due to the way the common Ethernet network switches provide dedicated bandwidth to each port on them. They also scale data throughput to the highest speed available between the client and the network switch that the client is connected to. If different clients are moving data at different speeds, the switch implements a buffer so slower clients can benefit from the data while the data is off the faster clients’ minds very quickly.

As you may have known before when you have worked with the computer network at work, or with your Internet experience, the Ethernet infrastructure can carry lots of different data.

This wiring practice will get the best out of the killer applications for these home networks i.e.

  • Internet access from everywhere in the house;
  • PC or console-based network / Internet gaming;
  • Online media derived from Internet services or media that is streamed around the house using DLNA-compliant equipment
  • Voice-over-Internet-Protocol telephony which is either being provided as part of a “triple-play” service or an alternative low-cost telephony service

amongst other activities.

There are infact some situations that may drive you to consider wiring your house for Ethernet, as outlined below.

Next-Generation Broadband Internet Services

A major trend that either is occurring at the moment or will be occurring over the next few years is the rollout of next-generation broadband Internet services. These services are typically based on a fibre-optic backbone with some providing fibre-optic connectivity to the customer’s door, and have a very high headline speed of at least 50Mbps for each customer.

These services will typically provide a “triple play” service with landline telephony, broadband Internet and multi-channel high-definition pay TV as part of the one service, delivered through the one high-speed pipe. You may experience a triple-play service with your broadband Internet service but the next-generation broadband service will provide the extra functionality like many full-HD video streams at once, HD-audio telephony with FM-radio clarity for voice communications, or video telephony that isn’t just confined to Skype or science fiction.

Of course, Ethernet would work well with these services by allowing the full bandwidth of these services to be exploited. This is because the high-speed data communications that the next-generation broadband services provides can be fully attained due to this connection being an “in-home data expressway” for the network. Here, it will benefit large file transfers that will become the norm as media content and computer software is delivered “over the wire” rather than as physical media. This also includes supplementing games with downloadable content such as characters or scenarios that add play value to the game.

This is even though the Wi-Fi wireless or HomePlug powerline technology will still work on shared bandwidth and work as a complementary setup for portable or ad-hoc-positioned devices.

IP-TV / Video-on-demand being part of the“Triple-Play” goal

Sony BDP-S390 Network Blu-Ray Player

This leads me on to talk about Internet-hosted video delivery services that are increasingly becoming the norm for video sources. Here the desire is to view these on the large-screen lounge-room TV and other TV sets in the house; and this application is being considered as a key application, if not the killer application, for the next-generation broadband networks.

This is being facilitated on two different grounds – one being to provide content that is either complementary to or an extension of what is offered by broadcast TV providers and the other is for telecommunications companies and Internet providers to distribute multi-channel pay-TV via the same Internet “pipe” as the telephone service and broadband Internet service.

The first situation, which is highly common in the USA, is to provide “over-the-top” video service where the Internet “pipe” is used by another operator to distribute streamed or downloaded video content independent of the established broadcasters. It manifests in the form of “download-to-view” video-content services like Netflix and Hulu or “complementary cable services” which provide channel groups that may not interest the main cable-TV providers, such as wholesome family entertainment or overseas / expat content in the US. Increasingly, network-enabled video products like games consoles, TVs and BD-Live Blu-Ray players are now using apps or extensions that support broadcaster “catch-up TV”, complementary-TV or video-on-demand platforms.

In this same manner, some users in the USA are looking towards “cutting the cord” – discontinuing their pay-TV subscription with their cable or satellite TV providers in order to save money and / or reduce exposure to the “many channels, nothing on” culture of cable TV there. Here, they are looking towards the “over-the-top” providers for content that would otherwise be on these cable TV services.

The second situation that is currently common in Europe, is “IP-TV”. This is where content from established free-to-air and subscription TV broadcasters is transmitted via an existing IP-based Internet-capable network. This method is being pitched as a way of using DSL or fibre-optic-based next-generation-broadband to distribute Pay-TV signals to subscribers. It has become more common with the ISPs and telcos moving towards offering the “single-pipe triple-play” services with regular telephony, Internet service and multi-channel pay-TV from the same entry point. This setup involves the telco or ISP providing the customer a set-top box (STB) or personal video recorder which plugs in to the router via an Ethernet cable.

As far as this application is concerned, a house that is wired for Ethernet is at an advantage for these “IP-TV” service. It benefits security of the conditional-access system in pay-TV applications because it is harder to unnoticeably “sniff” out conditional-access key values before they reach the set-top box; and there is a high quality-of-service due to the nature of “switched Ethernet” where high bandwidth and low-latency is assured for full-screen video. Also there is the ability to extend the service either through a “portable” setup where the set-top box is relocated at will or through having extra set-top boxes connected to secondary TV sets, this being a feature increasingly offered as a value-added option.

Of course, the Ethernet backbone will provide for improved quality-of-service that is needed for the full enjoyment of streamed and live IP-delivered video content.

Extending or improving the wireless network

Extended wireless-network connection diagram

The multiple-access-point wireless network used to mitigate Wi-Fi reception problems

 

By wiring your house for Ethernet, you are also laying an infrastructure that can definitely work “hand-in-glove” with wireless networking.

This is whether you have your home network based on a wireless backbone provisioned by a wireless router or you are starting from scratch with a wired backbone. If you were on an existing wireless network, you could set up your “fixed” nodes like desktop PCs to work on the Ethernet system.

This then leads to the wireless network being primarily of benefit to those devices that gain the most benefit from it i.e. portable or transportable equipment like laptops, smartphones and tablets.

You are also in a better position to improve your wireless network’s performance by implementing a practice that is performed in corporate, education or public wireless networks. This is to install one or more extra access points in areas where it is not possible to gain optimum reception from your primary wireless access point or wireless router using your existing portable nodes. All these access points are connected to the one wired-Ethernet infrastructure and set to similar network parameters so that the wireless client devices can seamlessly move between these access points depending on which one has the best signal strength. This is illustrated in the diagram above this text and discussed further in my article on improving your wireless network’s coverage.

This situation would mainly affect most pre-1950s brick houses with thick brick walls because such walls can easily attenuate the short-wavelength radio signal that wireless networks use. In some of these houses that have been recently extended, the wall that joins the extension to the main house is often a very thick one because it used to be the outside wall, and therefore becomes the point of attenuation for the short-wavelength wireless-network radio signals. The same situation can affect houses with chimneys that are on interior walls that adjoin rooms. In these houses, especially where there is a fireplace or the remnants thereof in both adjoining rooms, these walls are noticeably thick in order to accommodate the chimney and this situation can lead to poor wireless-network performance. It can also affect buildings that are insulated with foil-reflective insulation or use the new-look corrugated-iron wall as an outside-wall style.

This practice of using two or more access points would also permit optimum coverage of large houses by allowing one to deploy an access point close to each end of the house.

In the same manner, you can use HomePlug AV powerline networking to complement the Ethernet network by catering to those devices that can only use this technology; or as a secondary wired-network setup for ad-hoc use. This is done using a HomePlug-Ethernet bridge and that functionality may be built in to those routers and other devices that support HomePlug, as well as Ethernet and/or wireless as a LAN medium.

The reason this is going to be necessary in the long term because some manufacturers may decide to make network-capable devices that use an “existing-connection” method of providing network connectivity in order to save on design and manufacture costs. This is because they don’t have to add extra sockets on the device’s PCB for Ethernet or write in Ethernet-adaptor support into the device’s firmware. As far as the user or installer is concerned, there is no need to worry about making sure that there is an Ethernet connection accessible to the device or even connect another cable to that device.

Whether you have one computer or many on your premises; or whatever kind of internet service you are using, the improvement brought about by wiring for Ethernet will be seen as enhancing capital value for your premises. This may certainly pay dividends whenever you sell the house or let it out at a later date, because of the concept of pervasive broadband Internet becoming a reality. This brings with it a desire to wire up multiple computers to a network in order to share the high-speed Internet connection.

The Ethernet infrastructure has now existed on the same feature level as an intruder-alarm system as far as most customers are concerned when considering their next home.

The best time to wire for Ethernet

The best time to do this kind of work on an existing house is whenever you are doing works that are involving the house’s electrical system. This would involve rebuilding; refurbishing or extending the building or rewiring the building to comply with modern electrical-safety codes. It is also best done when you are constructing a new building from scratch and I would suggest that you raise this issue with your builder or architect during the planning stages.

This will mean that you may prefer to employ electrical contractors who are competent with telecom and data wiring. These tradesmen will advertise their competence by listing job types like telephones, networks, security and similar work in their advertisements and on their vehicles.

If you have a regular maintenance “sparkie” who does your repairs or other ad-hoc work, he may be able to do this kind of work or know of tradesmen who can do this kind of work on an ad-hoc basis.The reason is that this wiring can be done at the same time as the electrical wiring that is involved in the project.

It comes in to its own if there is “rough-wiring” being done before the walls are plastered or panelled; which is common during building work. Then you just need to have any fitting-off of sockets done when the walls have been covered and decorated.

If the job is essentially a re-wire job, the same electricians who do that job can pull the Ethernet cable through the walls while they lay the new AC wiring. By having the work done at the same time as any other major electrical work, you are in a position to gain maximum value out of your tradesmen who charge by the man-hour.

If you are installing an alarm system or doing similar work where new electrical infrastructure is being laid, you could have the Ethernet wiring laid at this point. This works best if the tradesman that you engage is competent at all facets of infrastructure work and will do this as part of the job.

Working on a budget

If you are on a shoestring budget, you may just focus on wiring the study / home-office and the main living areas in your house such as the family room and the formal living room or rumpus room. In this case, it is also worth making sure that there is an Ethernet connection on each floor of the house and at each end of the house. This is more important for older brick or stone houses that have been extended, so you can set up an extension access point that assures proper wireless coverage past the brick wall that separates the main house and the extension.

Then if you need wired network coverage in the rest of the house, you can use HomePlug AV hardware to cover those areas. But if you do intend to factor in adding extra Ethernet points at a later stage, you may want to make sure you can run that extra wiring through your house.

Planning ideas and issues

Central location

You will need to choose a location for the network switch, which is where all the data that passes the network goes through. It should be out of the way but easily accessible and shouldn’t be too hot.

The places that would come to mind are any built-in storage cupboards like the broom cupboard, the linen press or a built-in wardrobe in one of the bedrooms. You may use a place like the attic or basement. Some of you may want to place the switch in one of the cupboards in the home-office because this would be where the main “Internet-edge” router would be located and you could have the switch co-located with that router.

As I have seen for an alarm-system installation, you may use the wall hidden by the laundry door when it is open as a central location for the network switch. Ideally you shouldn’t use a room which is used for any heat-generating systems like hot water tanks, boilers or furnaces.

Co-locating with your alarm system’s panel

Tight central-location layout for Ethernet network

What to avoid when co-locating the Ethernet switch with an alarm panel or other similar equipment

This same location idea also allows you to establish an installation point for any devices that provide “back-end” functionality for the home like network-attached-storage devices. It then means that you can service all these devices by going to one location.

You may also have to be sure that you have enough space near the system’s central box and room at the power outlet to plug in another “wall-wart” power supply so you can install the Ethernet switch without reliability problems for the network and the alarm system. You could achieve this by using a good-quality power board (power strip) that has many power outlets on it and mount this on the wall, thus plugging your Ethernet switch, alarm system and other devices in to it.

The network switch

WD MyNet 8-port Gigabit Switch

WD MyNet 8-Port Gigabit Switch – an example of an Ethernet switch that works as the hub for your Ethernet network

As for the switch, you should purchase a Gigabit unit with more ports than there are rooms to wire. This allows you to add extra network points at a later date or connect network devices like Ethernet-powerline bridges, wireless access points, network-attached storage or home-automation equipment directly to the switch.

The preference for the Gigabit switches is driven by the fact that most desktop and mainstream laptop computers that have an Ethernet socket have this socket as a Gigabit Ethernet socket. Similarly, it is an expected feature that a well-bred network-attached storage devices on the market have this kind of high-speed connectivity. This also future-proofs the network for 802.11ac “Gigabit Wi-Fi” access points and the next-generation broadband services that are coming on the scene.

It is also worth being aware of and considering switches that work as Power-Over-Ethernet power sources. These units use the Ethernet wiring to provide power to suitably equipped network devices thus eliminating the need to run a power wire to these devices. This feature would be a boon for wireless access points and network CCTV cameras because it removes the need to make sure that there is a power outlet near these devices or risk them being “down” due to accidental power disconnection.

A brand that is still worth looking when you want to purchase Ethernet switches that are value-for-money is NETGEAR. From my personal experience and observations, this company has been known to be the first to offer particularly-desirable functionalities for these devices at reasonable per-port prices with such things as cost-effective five-port and eight-port switches, including some affordable Power-Over-Ethernet power-source models.

Broadband Internet

You will usually have the network-Internet “edge” router, whether it is the typical ADSL modem-router or a broadband router connected to a cable modem or similar broadband-technology device, either in the study, the home office or the main lounge area and will most likely have Ethernet-enabled devices located close to it. Here, you would connect one of the router’s Ethernet ports to the Ethernet installation while having the other sockets available for the other Ethernet-enabled devices like a games console, network-attached storage or network printer.

An increasing number of newer mid-range and high-end routers are coming out with all of the Ethernet ports being Gigabit Ethernet ports rather than the typical 10/100Mbps Ethernet connections offered on this class of device. This will be of benefit when you wire your home for Ethenet and want to have this backbone work at best speeds with the currently-available cost-effective Gigabit Ethernet switches.

Wiring the network

Rooms to wire

When wiring up for Ethernet, it is a good idea to provide a point in each bedroom as well as the kitchen, living room, dining room / family room and the study or home office. This means that you have covered every primary activity area in your home, thus permitting you to install network devices in each of these areas.

You may not think of wiring the living room for Ethernet but this room is where you will end up using networked entertainment equipment. A key example of this are the new “smart TVs”, Blu-Ray players and set-top boxes which have access to online video content or Internet services. They will also be able to draw down media content that his held on hard disks that are available to the home network. <Sony BDP-S390>

If you use an open-plan shared-purpose room like the kitchen / family room or living room / dining room, it may be a good idea to have a network point in each logical “room”. This will avoid the untidy look and safety hazard (to person, machine and irreplaceable items) of running long cords across the floor of these rooms.

Socket fittings

When choosing the socket type for the room sockets, it is best practice to use a standard wall-mount socket for each of these sockets. You may be tempted to use a side-entry socket, which is similar to some TV aerial points that have been commonly used in Australia or the older Telecom Australia telephone connector and these may work out for areas where space may be too tight due to furniture being placed against the wall. The only limitation with using a side-entry socket is that you may experience difficulty plugging and unplugging the device from the socket especially if the cable has the cheaper crimped-on connector.

If the job is aesthetically sensitive, you may be able to find outlet plates that work with the aesthetics of the room where the sockets are installed. This is easy due to the use of standard wall fitting designs that permit manufacturers to supply a large variety of trim-plates or socket modules. This can be of importance to anyone who owns a home that is styled to periods before the beginning of the “neat” 1960s and want to make the fittings reflect that style.

Multiple Points in one room

In some rooms like the kitchen or home office, you will need to be able to have more than one point in that room. This is because you will often end up with multiple devices in that same room.

Extra ports on the main switch

This method involves running extra wires from that room to where the main switch is located and using one of the vacant ports on that main switch. This may allow direct bandwidth being provided to the device that is connected to the port; and can therefore yield better performance for that device. This method also certainly comes in handy when the devices are spread around the room because the room has multiple activity locations such as open-plan living areas.

It would be more fault-tolerant due to the removal of another Ethernet switch that could be a point of failure for the network devices in that room.

Regional switch

This method requires all the network devices to be plugged in to a switch, which is uplinked to the network point that is in that room. This mainly works better for any setups where the devices exist in a cluster; such as a home entertainment centre or a home office / study room.

The only main problem is that if the switch is powered down, those devices lose network connectivity. This can be worsened by the way that “wall-wart” power supplies are often used for powering most switches, routers and other network-infrastructure devices. What this means is that these bulky power supplies can easily fall out of most power boards which have outlets that are spaced wide enough for ordinary plugs rather than these “wall-warts”.

This can be alleviated if there is use of Power Over Ethernet, which uses the same Ethernet cables to run low-voltage DC power to network devices. This avoids the need for power outlets to exist near Ethernet ports for devices like access points. The power is placed into the network via a powered switch or a midspan power injector and devices take the power off the network cables either via their own sockets or through a power splitter which connects to the device’s Ethernet socket and power socket.

The Power-Over-Ethernet setup has been assisted via the use of the IEEE 802.3af standard, which now means interoperability between different device manufacturers. As far as switches are concerned, this could mean that you could have a network-powered 5-port switch with “power forwarding”. This means that the switch can be powered via a network port from a Power Over Ethernet infrastructure rather than a “wall-wart”; and feeds power through at least one of its ports to a network device that is powered over the network.

It can also be alleviated if the switch is powered off its own outlet, which would be the case if it is hidden in a built-in cupboard. This also avoids the temptation for one to unplug the switch in order to run other appliances, which can lead to that part of the network being unexplainably down.

Expandable solution for built-in devices

Expansion Loop - current needs

An expansion loop satisfying current needs

One way to assure expandability for future network needs while saving costs on the current project is to create an “expansion loop” in areas where you may want to install built-in or concealed network devices or extra Ethernet sockets at a later date. One example may be the entertainment centre in the main living area where you may house your network-enabled home entertainment equipment in a cabinet. You may of course have an exposed Ethernet socket for the Internet-enabled HDTV or similar equipment.

By installing two Ethernet sockets in a cupboard such as the pantry, entertainment cabinet or built-in wardrobe, you would achieve this ability to cater for this situation. One of the sockets is wired to a visible point that is in the main area, such as at the breakfast bar. The other is wired to the main Ethernet switch for the home network.

These sockets could be installed in a “three-gang” or “four-gang” faceplate with blanking panels on the unused panels. Then, in the meantime, a straight-through Ethernet patch cable is plugged into both sockets. This then means that you are able to connect any computers or other network devices to this socket that is in the main area.

Expansion Loop - with extra devices or sockets

The expansion loop satisfying future needs at a later date

When the time comes to add a built-in Internet terminal or similar network device, or add extra network sockets in to that area; you or an installer, runs a short run of Ethernet cable from the new device’s or new socket’s location to where the two Ethernet sockets are. Then, a socket is installed at the device’s location and another Ethernet socket is inserted in to the abovementioned multi-gang faceplate and these sockets are connected to the Ethernet cable run. You then use a 5-port switch to connect this device and the existing network socket to the existing network backbone. Here, the switch is uplinked to the main Ethernet switch while the existing Ethernet point and the new device are connected to other ports on the switch.

This solution, which is illustrated in the two images here can also permit other “back-end” network devices such as security and home-automation “hubs” to be installed in this cupboard. As well, other network devices such as network hard drives and Ethernet-“no-new-wires” bridges can he installed in this location. It could even allow one to run extra Ethernet points in this same area at a later date.

Conclusion

Once you consider the idea of wiring for Ethernet, you would certainly have prepared your house for the connected home future. As mentioned before, this act of wiring for Ethernet will be even considered as a capital improvement, which may add value to your house in the Internet age.

You will also avoid the need to think about extra wiring chores should you think of implementing network-based home automation in the future, especially when most “connected-home” equipment will use a standard Ethernet connection on it.

My comments

The concept of VLANs and quality-of-service functionality is now become increasingly relevant to the home and small-business network now that the “single-pipe triple-play” and “next-generation” broadband Internet services are either here in your market or are coming around the corner to your market.

What are VLANs

The VLAN is a separate logical network path within a physical network medium, such as multiple SSIDs from one Wi-Fi access point serving different networks or a HomePlug setup with multiple Network Passwords for different networks. Most business-grade Ethernet switches offer this functionality in order to have particular Ethernet sockets associated with particular logical networks. It is used in many network applications such as interlinking a business with multiple premises through one multi-tenant building or providing Internet-only “guest access” service to business networks.

Now the VLAN is becoming common in small networks as part of either providing “guest access” or “hotspot service” to the Internet without encroaching on the security of the resident network; or providing dedicated “fast-lanes” for quality of service when it comes to A/V streaming or VoIP service.

NETGEAR’s role in this equation

Now NETGEAR have provided the GS110TP Gigabit Power-Over-Ethernet Smart Switch which is an 8-port switch which offers this functionality and Power-Over-Ethernet to all the ports for US$260. This is similar to how this company offered 5-port and 8-port 10/100Mbps Cat5 Ethernet hubs and switches at prices affordable for most people when the idea of home networking and broadband Internet came on the horizon in the early 2000s. Then a few years later, they offered 8-port 10/100Mbps switches with that had 802.3af standards-based Power-Over-Ethernet supply functionality on four of the ports, again at a price that most users can afford.

It may be easy to think of this unit being a candidate “central” switch when you wire your premises for Ethernet and want to make it future-proof for these new requirements. There have been some concessions to allow it to work properly with “triple-play” by the use of a default VLAN matrix with one VLAN for regular traffic, one for VoIP and one for video traffic. There is some “automatic-transmission” logic that shifts data to the different VLANs based on whether the data was primarily multicast in the case of video or one of a few VoIP protocols in the case of VoIP.

The main problem with this is that this switch wouldn’t work in a “plug-and-play” manner with “edge” devices that use certain VLAN setups or QoS methods to assure video and VoIP quality-of-service. For example, most of the “n-boxes” (Livebox, Neufbox, Freebox, Bbox, etc) used by French “triple-play” service providers as network-Internet edges have one Ethernet port for video traffic and three Ethernet ports for regular traffic. These units would expect you to connect the IPTV box to the “video” Ethernet port and you may end up with QoS or installation difficulties if you used this switch with them.

Limitations with this class of switch

For these switches to become easier to implement in a home or small-business network, there would have to be standards that allow an “edge” device to communicate its QoS and VLAN needs to these switches. This may be important if the “edge” device is managed by the service provider or is part of the provisioning chain that a service provider uses.

This may also include the flexible installation and “at-will” relocation of devices like VoIP handsets or IPTV devices as well as the support for multiple devices of this type across an Ethernet backbone. It also includes the support of multiple cascaded switches such as “regional” switches in other parts of the building or other buildings.

Other benefits to take note of

One bonus that I like about this switch is that it has offered 802.3af-compliant Power-Over-Ethernet across all Ethernet ports which allows the Ethernet cable to be a power cable as well as a data cable.This technology, which I will cover in a separate article on this site, has been pitched at business networks as being suitable for powering Wi-Fi access points, VoIP telephone handsets and IP-based surveillance cameras with one cable and from one point. Infact, NETGEAR have released an 8-port “regional” smart switch that has similar QoS and VLAN functionality but can be powered from this switch or other standards-based Power-Over-Ethernet networks.

Another feature that also appealed to me about this switch is that a unit of this price was equipped with optical-fibre LAN connectivity which can reduce the cost of using optical-fibre as a high-reliability long-distance link between buildings, especially on large properties. 

Conclusion

This is another example of NETGEAR offering technology that is deemed “large business” at prices that home users and small business can afford.

Feature Article – Wiring a house for Ethernet

Introduction

There may be a question that may come up when you build your new home or do renovations on an existing home. This question is whether to wire you premises for Ethernet or not and how to go about it?

What is involved when you wire for Ethernet

When you wire a house for Ethernet, you are providing a high-speed data backbone for your premises. This is achieved by laying Category 5 or Category 6 wiring from most rooms to a central location where there is a “switch” that moves data around the network at the appropriate speeds for the network devices.

The reason that it makes sense to consider the home-network issue, especially wired-in Ethernet, is because an increasing number of households are using two or more computers. Infact, there is an increasing trend for households to have more computers than TV sets. As well, computers can and have now become entertainment centres for bedrooms and other small areas thanks to DVD drives, sound-card setups and radio and TV-tuner kits that install in or connect to PCs. There is also an increasing common practice to copy CDs to the computer’s hard drive so that these computers double as personal jukeboxes, which is an asset with small areas. This means that there is a desire to have access to resources like the Internet and printers from all the computers that are in the house.

Similarly, there is new interest in the so-called “home theatre PC” where a computer is being used as a primary media center for the household. This is being achieved through the computer being housed in a case that is optimised for living-room use by having reduced operating-noise output and looking like a piece of home-entertainment equipment. These computers run an operating system that is optimised for viewing from a distance and optimised to do home-entertainment duties, plus being hooked up to the main living-room TV and sound system. This concept permits activities like the use of network media receivers as “media extenders” where one can “take” audio or video content to be viewed or listened to in other rooms.

If you have networked your computer equipment by using a “no-new-wires” method like wireless or HomePlug powerline; you may be dealing with a network that isn’t working at its best. This is because the “no-new-wires” technologies work on having the “no-new-wires” segment’s bandwidth shared by all the devices that connect to the segment. This is exemplified by poor response time during a network multiplayer game hosted across the “no-new-wires” segment or slow transfer speed whenever a file is being transferred between two nodes on the same segment.

Typically, when you implement a “no-new-wires” network, you would use a broadband router that connects to an Ethernet segment and the “no-new-wires” segment on the LAN side, like one of the many wireless Internet gateway devices. Also, if you decide to add on extra network devices, you would have to buy extra network bridges so these devices can work as part of the network.The possibility of high-speed Ethernet being available for home-computer users is made real through high-performance Ethernet network-connectivity devices being made affordable and ubiquitous for most users.

For example, there are Ethernet adaptors available for installation in PCI or ISA-based computers, or for quick connection to “sealed-box” computers via the USB port, or the PCMCIA or CompactFlash card slot. As well, allof the game consoles that are capable of online gaming have an Ethernet socket either built-in or as an extra-cost user-installed system accessory. Let’s not forget that most devices that connect to a network for some part of their functionality would have an Ethernet connector on board or on a supplied network adaptor module. Also, most newer computers are being supplied with built-in Ethernet connection abilities as a standard feature and people who build their own computers are now able to base their projects on Ethernet-equipped motherboards.

As well, the switches that are required as part of an Ethernet network are now available at very cheap prices. This all ends up with the Category 5 Ethernet medium being considered as a lowest-common-denominator for network connectivity.

Why wire a house for Ethernet?

You will benefit from the high data throughput that Ethernet provides in its current form – 100 Mbps, with 1 Gbps (1000 Mbps) being available now at a slight premium for new and existing small Ethernet networks. This will benefit applications like Internet gaming, network media streaming such as Internet radio; as well as graphics-rich printing.

You also gain the advantage of reliable network behaviour because you are not regularly sharing data transports that are prone to interference. This is due to the way the common Ethernet network switches provide dedicated bandwidth to each port on them. They also scale data throughput to the highest speed available between the client and the network switch that the client is connected to. If different clients are moving data at different speeds, the switch implements a buffer so slower clients can benefit from the data while the data is off the faster clients’ minds very quickly.

As you may have known before when you have worked with the computer network at work, or with your Internet experience, the Ethernet infrastructure can carry lots of different data.

This wiring practice will get the best out of the killer applications for these home networks i.e.

  • Internet access from everywhere in the house;
  • PC or console-based network / Internet gaming;
  • Streamed media around the house using DLNA-compliant network-media equipment
  • Voice-over-Internet-Protocol telephony which is either being provided as part of a “triple-play” service or an alternative low-cost telephony service

amongst other activities as outlined below.

IP-TV / Video-on-demand and the “Triple-Play” goal

There is increased interest in delivering video content over the Internet and being able to view it on the large-screen lounge-room TV.

This is being facilitated on two different grounds – one being to provide content complementary to or an extension of what is offered by broadcast TV providers and the other is for telecommunications companies and Internet providers to distribute multi-channel pay-TV via the same Internet “pipe” as the telephone service and broadband Internet service.

The first situation is to provide “over-the-top” video service where the Internet “pipe” is used by another operator to distribute streamed or downloaded video content independent of the broadcasters. It manifests in the form of “download-to-view” video-content services like Netflix, CASPA and Hulu or “complementary cable services” which provide channel groups that may not interest the main cable-TV providers, such as wholesome family entertainment or overseas / expat content in the US.  Increasingly, network-enabled video products like games consoles, TVs and BD-Live Blu-Ray players are now using apps or extensions that support broadcaster “catch-up TV”, complementary-TV or video-on-demand platforms.

The second situation comes to  “IP-TV” where TV signals are transmitted via an IP-based Internet-capable network. This method is being pitched as a way of using DSL or fibre-optic-based next-generation-broadband to distribute Pay-TV signals to subscribers. This has become more so with the ISPs and telcos moving towards offering “single-pipe triple-play” services with regular telephony, Internet service and multi-channel pay-TV from the same entry point. It involves the provision of a set-top box (STB) or personal video recorder which plugs in to the router via an Ethernet cable.

As far as this application is concerned, a house that is wired for Ethernet is at an advantage for the “IP-TV” service. It benefits security of the conditional-access system because it is harder to unnoticeably “sniff” out conditional-access key values before they reach the STB; and there is high quality of service due to the nature of “switched Ethernet” where high bandwidth and low-latency is assured for full-screen video. Also there is the ability to extend the service either through a “portable” setup where the STB is relocated at will or through having extra STBs connected to secondary TV sets, this being a feature increasingly offered as a value-added option.

Extending or improving the wireless network

Two access points used to extend wireless-network coverage in older house

Improving wireless-network coverage in older house

By wiring your house for Ethernet, you are also laying an infrastructure that can definitely work “hand-in-glove” with wireless networking.

This is whether you have your home network based on a wireless backbone provisioned by a wireless router or you are starting from scratch with a wired backbone. If you were on an existing wireless network, you could set up your “fixed” nodes like desktop PCs to work on the Ethernet system.

This then leads to the wireless network being primarily of benefit to those devices that gain the most benefit from it i.e. portable or transportable nodes like laptops, PDAs and Web tablets.

You are also in a better position to improve your wireless network’s performance by implementing a practice that is performed in corporate, education or public wireless networks. This is to install one or more extra access points in areas where it is not possible to gain optimum reception from your primary wireless access point or wireless router using your existing portable nodes. All these access points are connected to the one wired-Ethernet infrastructure and set to similar network parameters so that the wireless client devices can seamlessly move between these access points depending on which one has the best signal strength. This is illustrated in the diagram above this text and discussed further in my article on improving your wireless network’s coverage.

This situation would mainly affect most pre-1950s brick houses with thick brick walls because such walls can easily attenuate the short-wavelength radio signal that wireless networks use. In some of these houses that have been recently extended, the wall that joins the extension to the main house is often a very thick one because it used to be the outside wall, and therefore becomes the point of attenuation for the short-wavelength wireless-network radio signals. The same situation can affect houses with chimneys that are on interior walls that adjoin rooms. In these houses, especially where there is a fireplace or the remnants thereof in both adjoining rooms, these walls are noticeably thick in order to accommodate the chimney and this situation can lead to poor wireless-network performance. It can also affect buildings that are insulated with foil-reflective

This practice of using two or more access points would also permit optimum coverage of large houses by allowing one to deploy an access point close to each end of the house.

In the same manner, you can use HomePlug powerline  networking to complement the Ethernet network by catering to those devices that can only use this technology. This is done using a HomePlug-Ethernet bridge. This functionality may be built in to those routers that support HomePlug, as well as Ethernet and/or wireless as a LAN medium.

The reason this is going to be necessary in the long term because some manufacturers may decide to make network-capable devices that use an “existing-connection” method of providing network connectivity in order to save on design and manufacture costs. This is because they don’t have to add extra sockets on the device’s PCB for Ethernet or write in Ethernet-adaptor support into the device’s firmware. As far as the user or installer is concerned, there is no need to worry about making sure that there is an Ethernet connection accessible to the device or even connect another cable to that device.

Whether you have one computer or many on your premises; or whether you have broadband Internet or dial-up, the improvement brought about by wiring for Ethernet will be seen as enhancing capital value for your premises. This may certainly pay dividends whenever you sell the house or rent it out at a later date, because of the concept of pervasive broadband Internet becoming a reality. This brings with it a desire to wire up multiple computers to a network in order to share the high-speed Internet connection.

The Ethernet infrastructure has now existed on the same feature level as an intruder-alarm system as far as most customers are concerned when considering their next home.

The best time to wire for Ethernet

The best time to do this kind of work is whenever you are doing works that are involving the house’s electrical system. This would involve rebuilding; refurbishing or extending the building or rewiring the building to comply with modern electrical-safety codes.

This will mean that you may prefer to employ electrical contractors who are competent with telecom and data wiring. These tradesmen will advertise their competence by listing job types like telephones, networks, security and similar work in their advertisements and on their vehicles.

If you have a regular maintenance “sparkie” who does your repairs or other ad-hoc work, he may be able to do this kind of work or know of tradesmen who can do this kind of work on an ad-hoc basis.The reason is that this wiring can be done at the same time as the electrical wiring that is involved in the project.

It comes in to its own if there is “rough-wiring” being done before the walls are plastered or panelled; which is common during building work. Then you just need to have any fitting-off of sockets done when the walls have been covered and decorated.

If the job is essentially a re-wire job, the same electricians who do that job can pull the Ethernet cable through the walls while they lay the new AC wiring. By having the work done at the same time as any other major electrical work, you are in a position to gain maximum value out of your tradesmen who charge by the man-hour.

If you are installing an alarm system or doing similar work where new electrical infrastructure is being laid, you could have the Ethernet wiring laid at this point. This works best if the tradesman that you engage is competent at all facets of infrastructure work and will do this as part of the job.How to go about it

Central location

You will need to choose a location for the network switch, which is where all the data that passes the network goes through. It should be out of the way but easily accessible and shouldn’t be too hot.

The places that would come to mind are any built-in storage cupboards like the broom cupboard, the linen press or a built-in wardrobe in one of the bedrooms. You may use a place like the attic or basement. As I have seen for an alarm-system installation, you may use the wall hidden by the laundry door when it is open as a central location for the network switch. Ideally you shouldn’t use a room which is used for any heat-generating systems like hot water tanks, boilers or furnaces.

Tight central location layout for Ethernet switch

What to avoid when working out the Ethernet-switch location

If you are wiring an existing house for Ethernet and the premises is equipped with a security system, it is a good idea to locate this switch in the same area as this system’s central box. This means that if you decide to upgrade the alarm system to a more sophisticated security / home-automation “hub” that has a network interface, you can connect this unit to the home network cheaply and easily. In most cases, this kind of upgrade can be done with the same system peripherals (PIR and other sensors, siren, strobe light) all intact and able to work with the new system. You may also have to be sure that you have enough space near the system’s central box and room at the power outlet to plug in another “wall-wart” power supply so you can install the Ethernet switch without reliability problems for the network and the alarm system.

It also allows you to establish an installation point for any devices that provide “back-end” functionality for the home like network-attached-storage devices. It then means that you can service all these devices by going to one location.

The network switch

As for the switch, you should purchase a dual-speed (10/100 Mbps) unit with more ports than there are rooms to wire. This allows you to add extra network points at a later date or connect network devices like Ethernet-powerline bridges, wireless access points, network-attached storage or home-automation equipment directly to the switch.

There are many three-speed Gigabit Ethernet switches that are being sold at an extra per-port premium over the common 10/100 Ethernet switches. These would mainly appeal to those users who intend to work with high-bandwidth video or similar applications. They also have to work with network adaptors that are capable of working at the Gigabit speed, some of which are now under the $100 mark for a basic PCI unit. They are still worth considering if you want to have a future-proof high-speed Ethernet infrastructure.

It is also worth being aware of and considering switches that work as Power-Over-Ethernet power sources. These units use the Ethernet wiring to provide power to suitably equipped network devices thus eliminating the need to run a power wire to these devices. This feature would be a boon for wireless access points and network CCTV cameras because it removes the need to make sure that there is a power outlet near these devices or risk them being “down” due to accidental power disconnection.

Rooms to wire

When wiring up for Ethernet, it is a good idea to provide a point in each bedroom as well as the kitchen, living room, dining room / family room and the study or home office. This means that you have covered every primary activity area in your home, thus permitting you to install network devices in each of these areas.

You may not think of wiring the living room for Ethernet but this room is where you will end up using networked entertainment equipment. Such equipment could range from network media clients that either are connected to or are part of the TV and stereo to present digital photos, digital video clips and music files through these devices; through the popular online-ready games consoles like the PlayStation 3 and the Xbox 360, to dedicated media servers that present media that is stored on them over the home network. As mentioned earlier, an increasing number of affordably-priced desktop computers that are being sold by main-street computer stores are being designed to look like and behave like home-entertainment equipment, in order to be considered acceptable in rooms other than the study or kid’s bedroom. For example, you could easily think that a few of the newer home computers like the MSI MegaPC systems (Figure 2) resemble some of those bookshelf music systems that are sold at department stores and discount electrical stores.

Another reason would be that one may want to use a laptop computer in the living room during winter if there is an open fire, pot-belly stove or a radiant-style heater. This is because when these heat sources are in use, they become the focal point of the house.

If you use an open-plan shared-purpose room like the kitchen / family room or living room / dining room, it may be a good idea to have a network point in each logical “room”. This will avoid the untidy look and safety hazard (to person, machine and irreplaceable items) of running long cords across the floor of these rooms.

When choosing the socket type for the room sockets, it is best practice to use a standard wall-mount socket for each of these sockets. You may be tempted to use a side-entry socket, which is similar to some TV aerial points that are commonly used in Australia or the older Telecom Australia telephone connector. The problem with using a side-entry socket is that you may experience difficulty plugging and unplugging the device from the socket especially if the cable has the cheaper crimped-on connector.

If the job is aesthetically sensitive, you may be able to find outlet plates that work with the aesthetics of the room where the sockets are installed. This is easy due to the use of standard wall fitting designs that permit manufacturers to supply a large variety of trim-plates or socket modules. This can be of importance to anyone who owns a period home and wants to keep the fittings in tune with the home’s period.

Broadband Internet

You will usually the network-Internet “edge” router, whether it is an ADSL router or a broadband router connected to a cable modem or similar broadband-technology device, either in the study, the home office or the main lounge area and will most likely have Ethernet-enabled devices located close to it. Here, you would connect one of the router’s Ethernet ports to the Ethernet installation while having the other sockets available for the other Ethernet-enabled devices like a games console, network-attached storage or network printer.

Multiple Points in one room

In some rooms like the kitchen or home office, you will need to be able to have more than one point in that room. This is because you will often end up with multiple devices in that same room.

Extra ports on the main switch

This method involves running extra wires from that room to where the main switch is located and using one of the vacant ports on that main switch. This may allow direct bandwidth being provided to the device that is connected to the port; and can therefore yield better performance for that device. This method also certainly comes in handy when the devices are spread around the room because the room has multiple activity locations such as open-plan living areas.

It would be more fault-tolerant due to the removal of another Ethernet switch that could be a point of failure for the network devices in that room.

Regional switch

This method requires all the network devices to be plugged in to a switch, which is uplinked to the network point that is in that room. This mainly works better for any setups where the devices exist in a cluster; such as a home entertainment centre or a home office / study room.

The only main problem is that if the switch is powered down, those devices lose network connectivity. This can be worsened by the way that “wall-wart” power supplies are often used for powering most switches, routers and other network-infrastructure devices. What this means is that these bulky power supplies can easily fall out of most power boards which have outlets that are spaced wide enough for ordinary plugs rather than these “wall-warts”.

This can be alleviated if there is use of Power Over Ethernet, which uses the same Ethernet cables to run low-voltage DC power to network devices. This avoids the need for power outlets to exist near Ethernet ports for devices like access points. The power is placed into the network via a powered switch or a midspan power injector and devices take the power off the network cables either via their own sockets or through a power splitter which connects to the device’s Ethernet socket and power socket.

The Power-Over-Ethernet setup has been assisted via the use of the IEEE 802.3af standard, which now means interoperability between different device manufacturers. As far as switches are concerned, this could mean that you could have a network-powered 5-port switch with “power forwarding”. This means that the switch can be powered via a network port from a Power Over Ethernet infrastructure rather than a “wall-wart”; and feeds power through at least one of its ports to a network device that is powered over the network.

It can also be alleviated if the switch is powered off its own outlet, which would be the case if it is hidden in a built-in cupboard. This also avoids the temptation for one to unplug the switch in order to run other appliances, which can lead to that part of the network being unexplainably down.

Expandable solution for built-in devices

Expansion loop - current situation

Expansion loop - current needs

One way to assure expandability for future network needs while saving costs on the current project is to create an “expansion loop” in areas where you may want to install built-in network devices. This could be easily done for an Ethernet point that covers the kitchen where you want to be able to install a built-in Internet terminal like the IceBox FlipScreen kitchen entertainment centre at a later date; while catering for existing needs. At the moment, these devices are equipped with an Ethernet socket as their broadband / network connection method. The same practice can also be done for rooms like the master bedroom or the living room where you think that you may add extra built-in network devices or network points at a later date.

By installing two Ethernet sockets in a cupboard such as the pantry or built-in wardrobe, you would achieve this ability to cater for this situation. One of the sockets is wired to a point that is in the main area, such as at the breakfast bar. The other is wired to the main Ethernet switch for the home network.

These sockets could be installed in a “three-gang” or “four-gang” faceplate with blanking panels on the unused panels. Then, in the meantime, a straight-through Ethernet patch cable is plugged into both sockets. This then means that you are able to connect any computers or other network devices to this socket that is in the main area.

When the time comes to add a built-in Internet terminal or similar network device, or add extra network sockets; you or an installer, runs a short run of Ethernet cable from the new device’s or new socket’s location to where the two Ethernet sockets are. Then, a socket is installed at the device’s location and another Ethernet socket is inserted in to the abovementioned multi-gang faceplate and these sockets are connected to the Ethernet cable run. You then use a 5-port switch to connect this device and the existing network socket to the existing network backbone. Here, the switch is uplinked to the main Ethernet switch while the existing Ethernet point and the new device are connected to other ports on the switch.

Expansion loop - satisfying a future networking need

Expansion loop - satisfying a future networking need

This solution, which is illustrated in the two images here can also permit other “back-end” network devices such as security and home-automation “hubs” to be installed in this cupboard. As well, other network devices such as network hard drives and Ethernet-“no-new-wires” bridges can he installed in this location. It could even allow one to run extra Ethernet points in this same area at a later date.

Conclusion

Once you consider the idea of wiring for Ethernet, you would certainly have prepared your house for the connected home future. As mentioned before, this act of wiring for Ethernet will be even considered as a capital improvement, which may add value to your house in the Internet age.

You will also avoid the need to think about extra wiring chores should you think of implementing network-based home automation in the future, especially when most “connected-home” equipment will use a standard Ethernet connection on it.
