Previous Coverage about Wi-Fi 7

What is Wi-Fi 7 to provide for yoThur Wi-Fi wireless network?

My Comments

This year (2024) is being seen as a year for Wi-Fi 7 to gain legitimacy as a Wi-Fi network technology for the home and small-business network space. It is because the Wi-Fi 7 (802.11be) standard was set in stone on January 8 2024.

This will be about leading wireless networks towards multiple-gigabit networking, something that will be facilitated by Gigabit fibre Internet-service networks that can be easily upgraded to this direction. There is expected to be reduced latency which will benefit online-multiplayer video games, videoconferencing and similar time-sensitive activity. There will also be time-sensitive network support at the media level that will benefit multichannel sound, multi-camera video production, robotics and the like.

But these networks still work on a “best case” approach but in a way that permits Wi-Fi 7 networks to support equipment that works to prior standards.

What is now happening is that more telcos and ISPs are being offered home-network routers that support Wi-Fi 7 and offer these kind of advantages. This is something to be expected of in a competitive market like France where Free is offering the Freebox Ultra (Product Page – French language / Langue française) which is the first “n-box” router to work Wi-Fi 7. along with 4 2.5 Gigabit Ethernet ports.

ZTE’s Wi-Fi 7 router lineup

ZTE is coming forth with a range if Wi-Fi 7 routers and access points – a range of 10 models covering every possible configuration with some routers supporting FTTP setups and DSL-copper setups as well as broadband Internet, Then Vantiva demonstrated their EasyMesh-compatible Wi-Fi 7 extenders alongside their 5G fixed-wireless modem routers at Mobile World Congress 2024. Here, most of this equipment will be made available to telcos and ISPs who are offering Gigabit Fibre Internet services. As well, Netgear and TP-Link are offering a range of Wi-Fi 7 compatible routers, distributed Wi-Fi systems and access points in their home-network product ranges, typically for high-performance users.

There is still a trickle of client-side equipment with Samsung S24 Series smartphones and the Google Pixel 8 Pro smartphone being the first recognised smartphone model to support this technology. But this year, Wi-Fi 7 will become part of product refreshes for smartphones, tablets and laptops at the premium end of the market.

The fact that network equipment manufacturers are offering Wi-Fi 7 routers ‘under contract” to telcos and ISPs for sale or lease to their end-users and that the next generation of smartphones is to have Wi-Fi 7 shows industry confidence in that standard. It would still be a valid upgrade for networks running Wi-Fi 5 or prior-technology equipment especially if the equipment is significantly old. Or as the equipment comes in to affordable mid-range territory, it could be seen as a long-term upgrade for your Wi-Fi network.

As well, it could encourage the sale of multi-Gigabit Ethernet switches due to a need to have at least 2.5 Gigabit as a wired backhaul option for distributed or many-access-point Wi-Fi 7 networks with 2.5 Gigabit unmanaged basic 5-port switches coming in to very affordable territory.

What do I mean by a “small logical network”

Through this Website, I often talk of a “small logical network” when describing the kind of networks that connected devices can use when there is the desire to work with each other.

What is a “Small logical network”

This is a network typical of one set up in your home or small business as a primary network primarily by people who live in your home or work in your business. Here, the network is intended to be used by people who effectively know each other.

Basic DLNA Media Network

Basic DLNA Media Network – an example of what the small logical network is about

It can use Wi-Fi wireless technology; Ethernet new-wire technology; or a “wired no-new-wires” technology like HomePlug / G.Hn HomeGrid powerline, or MoCA / G.Hn HomeGrid TV coaxial cable; or a combination of these physical-connection technologies. But this network is connected to the same router / Internet-gateway device and established as one network.

The router device will use DHCP to allocate the IP addresses to each device from a particular pool of addresses so that they are discoverable across this network. It is also configured without any isolation across this network so that the users’ devices can discover each other across the network. This is important for file transfer across the network, printing (including driver-free printing) to network-connected printers, and AV / multimedia protocols and setups like network-based multiroom setups, AirPlay, Chromecast or UPnP AV / DLNA, with this concept being highlighted in the diagram opposite.

Guest Network Functionality

An increasing number of routers are supporting the creation of “guest networks” which are another logical network that may be used for tenants or guests. These networks have a different set of IP addresses and can’t discover the devices associated with the main network, although they can gain access to the Internet service.

These can either be set up to be another small logical network with device discovery within that network or as a public-access Wi-Fi network of the kind outlined below that doesn’t support device discovery across that network.

Public-access Wi-Fi

A properly configured public-access or community network is set up for device isolation so that the devices which use that network cannot discover each other but can discover the Internet connection. This is because such networks are used by people who don’t really know each other. Such networks wouldn’t fit in to that term of a “small logical network” that I use on this site because of the emphasis on device-to-device discoverability.

Newer hospitality networks

But tech vendors courting the hospitality and allied trades are working on network setups where each room or apartment of the facility has its own logical network. This is provided by a Wi-Fi network name (SSID) and password that is peculiar to the room or apartment and will last for the duration of your tenure. You will either have a docket with that Wi-Fi network name and password when you rent the room or even scan a EasyConnect QR code to enrol your device.

Then, when you enrol each of your devices to that network, they see each other as though they are a member of a home network. Some of these “solutions” vendors are even integrating devices like connected entertainment endpoints (Chromecasts, Apple TVs, smart TVs, Internet radios, etc) that work with these networks and are discoverable using the usual suspects (AirPlay, UPnP AV / DLNA, Chromecast, Spotify Connect, etc).

But this is distinct from a simple property-wide network like the headline Wi-Fi network that is pitched for use by guests that would be properly set up to isolate each device that uses the network. It is also distinct from the premise’s back-of-house network that is used for the hotel’s business IT needs.

Enterprise networks

Larger enterprise networks are typically engineered in a more intricate manner so that data flows within particular segments of that large organisation. This will typically be about the use of multiple virtual networks or multiple logical networks and even authentication routines not associated with the typical small network such as certificates.

Dependent on the use case, each logical network within an enterprise setup would be set up so that devices logged in to that network can find each other or they can be set up with the abovementioned device isolation.

Similarly, they will implement the Enterprise variations of the Wi-Fi WPA2/3 security protocols that use advanced sign-in requirements like usernames and passwords or device-local certificates. Most devices typically used on a home network wouldn’t support networks that use these kind of advanced security protocols.

Mobile networks

Mobile wireless network for two or more mobile devices and mobile client devices – uses a router-class device like a “Mi-Fi” router

A small logical network can be created in a mobile environment through the use of a travel router or MiFi-type mobile broadband modem router. Some mobile NAS units also provide this kind of facility. Even a regular computer running recent versions of MacOS or Windows can create its own small logical network while connecting to a public-access Wi-Fi network thanks to “mobile hotspot” or “Internet Sharing” functionality.

Here, the Wi-Fi network that these devices create is essentially a small logical network as if it is acting as a home-network Wi-Fi router. This is typically used to connect a Chromecast, Apple TV or similar network-based multimedia device to your hotel’s Wi-Fi guest-access network in order for you to stream multimedia to that device.

Conclusion

The idea behind the small logical network is a network, independent of connection media, that exists behind a single router device and allows each device on that network to discover and connect to each other.

How can Starlink improve their end-user equipment?

Starlink could improve their satellite terminals further for advanced use cases

As I see Starlink build up its low-earth-orbit satellite Internet service, I would need to see them provide services that can answer particular user needs better.

But I would see Starlink offer these kinds of improvements as they refresh their consumer equipment or whenever there is competition afoot. This could be in the form of Amazon’s Project Kuiper constellation or the OneWeb constellation that will be offered through a variety of telcos and ISPs.

A satellite terminal that provides a WAN connection to the customer

At the moment, the Starlink terminals offered in the retail marketplace have a built-in Wi-Fi-only router. But I would like to see them offer terminals with a “WAN-level” Ethernet output that allows the terminal to work with an external broadband router.

Using Starlink with advanced routers like the TP-Link Archer AX6000 Wi-Fi 6 broadband router

This may suit a range of consumers who need a better router than what Starlink builds in to their own terminals. Firstly, there are business users who would prefer to use business-grade equipment that offers what they need for their Internet connection such as VPN endpoint functionality or business-grade Wi-Fi segments that implement “enterprise-level” features. It can also encompass the use of routers that are optimised for offering public-access Internet service or even the use of high-performance routers for activities like online games.

There is an increasing range of multi-WAN routers that have two or more WAN / Internet sources, whether that be through an integrated modem like a cellular modem or an Ethernet connection. These arrangements would come in to their own for fail-safe Internet connections or to provide load-balancing or increased throughput (“fat-pipe” operation) for the Internet connection.

Add to this the use of distributed Wi-Fi systems that have one of the modules working as a router while the other devices work akin to an access point. This would come in to its own with larger rural and remote properties where there is a desire to assure property-wide Internet and home-network access. Various standards like Wi-Fi EasyMesh and some newer Wi-Fi variants pitched for long-distance networks could lead to innovation when it comes to rural-property Wi-Fi coverage.

This could be facilitated with a modem-router satellite terminal that has at least one Ethernet port and supports a “modem” or similar operating mode. Such a mode would then support the use of an external router.

At least one Ethernet LAN connection on modem-router satellite terminals

QNAP 2-disk NAS

Having Ethernet on Starlink satellite terminals could allow them to work with NAS storage devices and similar devices

There are uses who would rather benefit from having a wired LAN segment as part of our home networks. This would require at least one Ethernet LAN port on the router. Some of the use cases would include NAS devices, smart TVs, desktop computers and the like or creating a multi-building home network which may appeal to a lot of farmers with barns and the like.

The pleasure-boat user class could also benefit from Ethernet LAN connectivity especially where there are marine electronics devices that handle large amounts of data like marine radar or electronic mapping systems. I would also extend to this network-connected AV equipment used on board a cabin cruiser, narrowboat or similar vessel where such vessels have at least one living area like a saloon where a TV with online-video services may be installed. Here, this user class can then benefit from a vessel-wide Ethernet network segment that answers all of these needs.

This user class could be served by either a satellite terminal that provides a WAN-level Internet connection that is used with a broadband router that has at least one Ethernet LAN port. Or a satellite terminal that provides at least Ethernet LAN connection in addition to Wi-Fi as has been done with most modem-router products.

Factoring in mariners who only do limited sailing

Pleasure-boats at a marina in Melbourne

Starlink could offer better tariffs for people who use boats on inland waterways, on neighbouring islands or on their continent’s coast.

There are a significant number of mariners who sail only within inland waterways like lakes and rivers or sail along a small portion of their home continent’s coastline such as within a bay or estuary. It may also extend to people who sail a short distance between islands or from a continent to its neighbouring islands.

At the moment, such mariners who want to benefit from Starlink are asked to pay dearly for their service because it is assumed they intend to go to the oceans. This is even if they are just after a water-resistant marine-friendly modem for their craft while working within the inland waters or similar areas.

What could be looked at is a reasonably-priced service price tier for Starlink services used on small pleasure craft working within certain waterway classes like inland waterways, bays and estuaries, archipelagos of islands or close to the coastline. This factors in most pleasure-craft users who own reasonably-priced vessels with limited navigation abilities rather than those using more expensive craft like superyachts that have wider navigation abilities. As well, it could be about small-time fishing boats, scientific-research craft and the like being able to benefit from Starlink satellite broadband Internet. It could even factor in those of us who keep these boats tied up at a marina as a “holiday house” but take them out on the water on occasions.

Conclusion

These kind of options could come about as an increase in competition starts to exist between low-earth-orbit satellite operators. Here, it would manifest in a variety of hardware for these systems or an increase in the number of reasonably-priced consumer tariffs for these services.

They could also make satellite Internet appeal to an increased range of users who exist in regional, rural and remote areas including the waters.

Chromecast or Apple TV within a public-access Wi-Fi network

Chromecast and similar devices are being used as an alternative to smart TVs

How you can use a Chromecast or Apple TV in that hotel room

There are situations where you may want to use a device like a Chromecast, Apple TV box or a network printer in a place like a hotel that has that headline public-access Wi-Fi network facility. Or you may want to make use of a portable Internet radio to listen to that Internet-hosted radio station at the worksite you are working at which has a public-access Wi-Fi network.

But you will find it difficult to use these kinds of devices on these networks for many reasons.

One of these is that if a public-access Wi-Fi network is properly setup, each device that is on the network is to be logically isolated so that other devices on that network can’t discover your devices. This is more to assure user privacy and data security for all network users.

But this will interfere with arrangements where you need to discover another device that you own that is on the network in order to use it, such as to “cast” media to a Chromecast or Apple TV. It can also interfere with file sharing between two computers or the use of portable NAS devices.

Sony CMT-MX750Ni 3-piece music system – this has been used to try Internet-radio functionality via a public-access Wi-Fi network

As well, some of these networks are set up with a Web-based captive portal or implement Wi-Fi PassPoint / Hotspot 2.0 or other authentication approaches. This is even if it is about assenting to the terms and conditions of service for use of the public-access Wi-Fi network. Here, these kinds of login experiences don’t work at all with devices that have a limited user interface like a small display or a user interface based around a D-pad. In a lot of cases, you will deal with devices that don’t even have a Web browser at all to work with these captive portals.

I previously covered Wi-Fi mobile networks and how they work. This included the use of travel routers or Mi-Fi devices, or NAS and similar devices that support “Wi-Fi to Wi-Fi routing”.

Travel Routers and portable NAS devices

Mobile NAS as bridge setup

Wireless NAS as a bridge between mobile client devices and another Internet-providing network. This is a similar setup for travel routers that support “Wi-Fi to Wi-Fi” operation.

One approach is to use a travel router or Wi-Fi-capable portable NAS that supports “Wi-Fi to Wi-Fi routing”. This means that the device connects to the public access network while creating its own Wi-Fi network, acting as a router. With Wi-Fi-capable portable NAS devices, you have to enable this function through something like enabling “Share Wi-Fi Connection”. You have to set the NAS so that the data that it has is not shared to the Wi-Fi network it is connected to, something you do when you set up “secure” or “private” operation.

Newer multimedia-ready hotel-room networks

Be also aware that there is an increasing number of network solutions being pitched to hotels and similar lodging establishments that create small home-network-grade Wi-Fi networks unique to each room or apartment. Some companies are even pitching this as part of their public-access Wi-Fi solution or building-wide network / Internet solution for residential or accommodation places like hotels or build-to-rent apartment buildings.

This is achieved through a distinct room-specific network served by a router installed in the room or a VLAN specific to a room or account and operates for the user’s tenure that works like a small home network.

These setups may also be to support a TV or audio setup enabled for Google Chromecast, Apple AirPlay, DLNA, Spotify Connect or other common home-network media protocols. The TV or audio setup is something that a hotelier would like to provide as an amenity to their “switched-on” guests who make use of online services and smartphones for their multimedia consumption. Such networks will typically have a “small-network-standard” Wi-Fi network covering your room or suite and will have an SSID network name and password peculiar to that network.

Most likely, if you do bring along your equipment and have it work with the room-specific multimedia network, you will be able to discover it as long as your computer or mobile devices are linked to that particular network. This could mean that your Spotify-Connect-capable wireless speaker could work with Spotify on your smartphone like it does at home if all these devices are connected to the room-specific network.

You may find that the hotel you are staying in may be set up this way and there could be printed material in your room about this kind of network existing and how to “get on board”. Typically this requires you to connect your smartphone and your devices to the room-specific network once you have activated that network connection.

Your regular laptop computer as a travel router

Your laptop that runs Windows 10 or MacOS 13 Ventura or newer operating systems also offers this same functionality

Laptops that run Windows 10 or MacOS 13 Ventura onwards can offer this same functionality natively. This is infact an approach that I used to run my Chromecast with Google Play as an audio-video output device for my Samsung Galaxy A52s smartphone at the Elsinor Motor Lodge in order to play my music through the motel room’s TV speakers.

Windows 10 onwards

Enable the Mobile Hotspot option in Windows 10 or 11 so your laptop becomes a travel router or mobile hotspot

  1. Select “Settings” which is the gear-shaped icon to open the Settings menu
  2. Select “Network and Internet” on the left of the Settings screen to open the Network and Internet window.
  3. Enable Mobile Hotspot whereupon you will see the setup for sharing your computer’s Wi-Fi connection.
  4. To see your hotspot properties, click the “ > “ next to the “Enable Mobile Hotspot” toggle. Note down the Network Properties on this screen which correspond to the SSID (Network Name) and Password for the Wi-Fi hotspot created by your Windows computer.

    Windows 11 - Network And Internet - Mobile Hotspot Settings

    These are the settings you need to go over to make sure your mobile hotspot works. The network details refer to what your devices need to be connected to.

MacOS 13 Ventura onwards

  1. Click the Apple icon at the top left of the screen and select “System Settings
  2. Select “General” then select “Sharing
  3. Look for “Internet Sharing” and click the i nearby that option
  4. Select the network connection that has the Internet service – this could be Wi-Fi or Thunderbolt Bridge.
  5. Select the network connection the other devices will connect to using the “To Computers Using”, which will be Wi-Fi
  6. You then have the option to create a Network Name (SSID) and Password for the hotspot network. Note down the SSID and Password you created for the hotspot,
  7. Once everything looks OK, click Done and toggle Internet Sharing on.
  8. Click Start in the pop-up message to confirm Internet Sharing.

Setting up your devices

Then, set up your devices like your network media player or network printer to link to the hotspot network you created in the above steps. Most network media devices will require you to go through the “manual Wi-Fi setup” process with some devices, especially speakers, requiring you to link to a “setup” Wi-Fi access point integrated in the device and running a setup Website hosted by that device.

That also means that your smartphone or tablet has to connect to the hotspot network if it is to benefit from the devices that you connected to that network. This would be important for media-sharing protocols like Chromecast or DLNA, or network-printing protocols like AirPrint or Mopria.

When you are finished

If you are using Windows or MacOS as a travel router, turn off the “Mobile Hotspot” or “Internet Sharing” functionality before you pack up your equipment. This is to assure secure operation and also saves on battery power for your laptop computer. With a travel router or portable NAS, you just simply disable the network-sharing functionality when you pack the equipment up.

Remember that the settings will stay the same for your Mobile Hotspot or Internet Sharing functionality so you don’t need to connect to a new Wi-Fi network if you use the same method again. This also holds true for travel routers or portable NAS units that implement network sharing.

In the case of that multimedia-ready hotel room network, you will still have to connect your equipment including your computer or mobile devices to these networks when you set yourself up in your room. This is because the guest credentials are likely to change as a means of protecting guests’ own equipment and experience.

Wi-Fi Sensing is now given some real use cases

In-vehicle presence detection

From the horse’s mouth

Wi-Fi Alliance

Lisbon demonstration showcases how Wi-Fi Sensing can assist in a critical scenario | Wi-Fi Alliance

My Comments

The Wi-Fi Alliance is extending the Wi-Fi network technology beyond a local data network technology towards a presence and movement sensing technology.

This can exploit newer Wi-Fi technologies like Wi-Fi 5 onwards which implement MIMO multiple-RF-frontend technologies; or the increasingly-common multiple-access-point Wi-Fi networks. Here, it is about sensing disturbance in electromagnetic wave patterns that are the basis of radio technology whenever people or things move about.

A viable use case that has been demonstrated is a “child presence detection” setup for motor vehicles. Here, this detects the presence of a baby, small child or dog within a motor vehicle’s interior and alerts the driver to the child’s or animal’s presence. This is to avoid incidents like the toddler who was “forgotten” in a childcare facility’s minibus where the child was at risk of overheating for example due to it being asleep and out of sight in the vehicle.

This approach doesn’t just sense the presence of the child in a closed vehicle but also monitors biometric signs like breathing so it is a live person or animal. As well, it is based around two Wi-Fi access points within the vehicle – one on the driver’s side of the dashboard and one under the front passenger seat to create the sensing envelope. This is typical for most passenger cars with the front seat row and the back seat row but could be reworked for larger vehicles like station wagons or minibuses.

Once proven in a real world situation, this use case could be about a feature that is mandated by motor-vehicle safety standards bodies as part of a vehicle’s safety rating or as a mandatory feature for vehicles to have before they are on the market.

It is also being seen as a technology to identify whether someone in the house has breathing issues along with simple use cases like presence and motion sensing within the house for energy efficiency, security and convenience functionality in the smart home. I would also see it as a boon towards independent ageing at home by detecting falls for example.

What is happening is that Wi-Fi technology will come in to play for more than just a backbone for a home network. Here, it would be about safety or in-home healthcare that assures some form of independence. This is while it can still serve that role of a data network backbone.

Wi-Fi to become strong as a location and range-finding technology

Wi-Fi Location™: Performance drivers for Wi-Fi® ranging technologies and its achievable accuracies

My Comments

Qualcomm is driving Wi-Fi further as a location and ranging tool through the use of its own silicon. This is in addition to the Ekahau effort to use Wi-Fi as a real-time location system for business.

But it’s more about making sure that the Wi-Fi network is capable to answer Bluetooth and UWB wireless technologies in this space. This is being facilitated by Wi-Fi devices having multiple antennas and operating on multiple bands, That can exploit different bands’ radio-frequency characteristics like transmission / reception range.

In the business world, this may be about staff or asset tracking, indoor navigation amongst other uses. It may even be about “pointing” a laptop, tablet or smartphone to the closest printer or similar peripheral so you cut down on the amount of time it takes to select that peripheral. Airports, shopping centres and similar places will benefit in the form of enhanced indoor navigation for staff and end-users.

But as far as the Wi-Fi home network is concerned, this could come in to its own in a strong way.

This would be facilitated by the use of most recent-issue value-priced and premium Wi-Fi routers having multiple antennas thanks to newer Wi-Fi iterations like Wi-Fi 5, Wi-Fi 6 and Wi-Fi 7 that implement various MIMO techniques; along with the ability to work on multiple wavebands.

Then there is an increased interest in multiple-access-point Wi-Fi networks thanks to Wi-Fi repeaters, distributed Wi-Fi (mesh) networks and access points that use Ethernet or wired “no-new-wires” networking technology like powerline networks as a backhaul. This is often implemented to fill in Wi-Fi dark spots within your home caused by things like highly-dense building materials or metal used as part of building materials or insulation.

Even distributed Wi-Fi setups like this NETGEAR Orbi with WI-Fi 6 system will serve the same purpose

One key use case for the home is the smart-home technology based on “Internet of Things” devices. The classic use cases would be the robot vacuum cleaners that move around your house, keeping the floors clean or the robot lawnmowers that keep your lawn mown down.

In the context of home and automotive security, it could be about geofencing and similar algorithms that limit the operation of smart locks or vehicle locking systems. It could even extend to preemptive control of heating / air-conditioning and lighting so when you are near home, the heating or lights come on.

To some extent, this could extent to healthcare at home including ageing at home. For example, this may be about fall detection or wandering detection for dementia sufferers. Or it could be about proof-of-presence and time/attendance records for paid carers.

The “nearest peripheral” location will come in to its own with the home network if you have multiple network-capable TVs or printers on your premises. Here, it could be about having the default printer being the one that is closest to you even if you take your laptop to the kitchen for example. It could also extend to use of Wi-Fi Aware for “across-the-room” use cases like transferring data between devices or user discovery with social media and online games.

Therefore in a lot of use cases, Wi-Fi will be valued as a location and ranging technology even if the network of concern is a small network that covers a house or small business.

Why I still see wired network backhauls relevant even with newer Wi-Fi versions

D-Link DIR-X5460 Wi-Fi 6 router press picture courtesy of D-Link USA

Some building setups may not allow a Wi-Fi router like this D-Link Wi-Fi 6 unit to work at its best in covering the house

With Wi-Fi 7 around the corner, a company who is designing silicon for that new Wi-Fi standard is running a line that wired networks will be obsolete.

But it is a bit too hasty to state that because there are situations where the wired network will still be relevant as a backhaul for that Wi-Fi 7 wireless network. Here, I encompass both the Ethernet networks built on Category-5 or Category-6 cable along with “wired no-new-wires” networks like HomePlug powerline or G.Hn networks based on powerline, telephone wire or TV coaxial cable.

How are your premises built?

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

That thick wall may cause Wi-Fi not to work properly

If you find that your premises is built of dense building materials like brick, masonry or cinder-block / concrete block, you may find that you have trouble with your Wi-Fi network’s coverage. This is more so where any of the interior walls uses those kind of materials.

Examples of this may include a double-brick house that had an extension built on to it or a house that has one or more brick interior chimneys. Similarly, apartment dwellers may run in to this problem if two or more of their apartment’s interior walls touch their building’s “service core” plenums used for the elevators, garbage chutes or as “risers” for plumbing and wiring. Such a plenum is typically made of thick or reinforced concrete to satisfy noise-level or fire-safety expectations.

Another building material to watch for is metal. This may be used for reinforcement like with reinforced concrete, or it could be used as a mesh or for decorative effect like with corrugated iron used to give that rustic look. Add to this insulation material that is augmented with foil to improve its effect. This material has that “Faraday cage” effect where it reflects radio waves rather than passes them.

As well, the radio frequencies that are more affected are those at the higher end of the spectrum due to their short wavelength. This will be more so as wireless networks extend in to the 6GHz territory.

These situations will call for a wired network backhaul in order to create building-wide coverage for your Wi-Fi network.

Multiple-building setups

Methods to link buildings in a multiple-building home network

Another situation that will be of relevance to suburban and country living is the want to connect secondary buildings like a barn, cabin or granny flat to your primary house. This would also apply to the use of a caravan or campervan as secondary living quarters.

It would be more so as you think that bringing your home network and Internet to these buildings that you expect to have as part of your living or  space and is something I have covered in a feature article and infographic. Here, a wired link can earn its keep in these kind of setups and may allow you to be more flexible with building materials for the secondary buildings or main bouse.

A new-wire approach can be in the form of Cat5e cable could give up to 2.5 Gigabits per second bandwidth over 100 metres, something that would be affordable for most. If Cat6a cable was used, this could go to 10 Gigabits per second for the same length. The more premium fibre-optic technology would be able to achieve 300 metres for stability and 10 Gigabit throughput. The Cat5e setup would come in to its own with fixed outbuildings built relatively close to the main house like in most low-density living areas including most smallholdings.

Use of powerline-based “wired no-new-wires”  like HomePlug AV2 or, especially G.Hn HomeGrid, would come in to its own here. This is more so if you are renting your home or are dealing with caravans or campervans being purposed as sleepouts for example and you have them connected to your home’s mains supply.

Other factors to consider

Some devices may also cause issues when it comes to Wi-Fi coverage due to their design.

For example, a flat-screen TV will use a significant amount of metal as part of its chassis and this can act as an RF barrier. Similarly furniture made out of sheet metal like the traditional office filing cabinet can also be an RF barrier.

These “RF barriers” can effectively create an “RF shadow” if the client device is located close to them and such items are located close to each other.

It is also worth considering that wired network technologies, especially those based on Category 5 or Category 6 twisted pair copper cable or fibre-optic cable will be developed in a way to have more bandwidth than Wi-Fi-based wireless technologies. Here, it takes advantage of “pure-play” wiring infrastructure that is predictable in signal quality and reliability. This will underscore the role of these technologies as a reliable high-speed backhaul option between devices or Wi-Fi access points.

Conclusion

Due to facts like dense or metallic building materials, multiple buildings on a property or metallic objects, wired networks will still be considered relevant in the era of Wi-Fi 7. Add to this that wired networks, especially those using dedicated wiring infrastructure, will still be worked on as something that offers higher data speeds than equivalent Wi-Fi technologies.

G.Hn HomeGrid to be the direction for wired no-new-wires networks

The International Telecommunication Union’s G.Hn HomeGrid standard is expected to become a significant new direction in “wired no-new-wires” network technology. Such technology makes use of wiring infrastructure that is in place within a premises for purposes such as providing AC mains power, providing a telephone service or connecting a TV to an outdoor TV antenna or cable / satellite TV setup.

This is for both the in-premises local-area network and for the Internet / WLAN “access” network that brings your Internet service to your home-network router.

This technology primarily works as an alternate powerline / AC-wire network technology to the established HomePlug family of powerline-network technologies. But it is also competing with MoCA for the TV coaxial-cable medium and the G.Hn HomeGrid Forum took over the HomePNA standard for phone-line-based on-premises networks.

Media types

Powerline

Use of a building’s AC wiring infrastructure is considered more credible due to the fact that there are many power outlets across a typical home. I have even had good experiences with this kind of network especially for extending Wi-Fi coverage or even extending a home network out to a detached garage that served as a “man-cave”.

The HomePlug Alliance had effectively abandoned continual development of the HomePlug series of powerline-network standards. At the moment, the latest standard is the HomePlug AV2 MIMO which can go to 2000Mbps,  That is although a significant number of device manufacturers and IT retailers are continuing to make devices that work to the 1200Mbps bandwidth.

G.Hn HomeGrid has taken the powerline network further by offering the HomeGrid MIMO variant that cam move at least 2000Mbps of data. Like the HomePlug AV2 MIMO standards, this uses the active / phase / line, neutral and earth / ground wires of the mains-power plug to carry the data, thus assuring users of robust data transmission across a building’s general AC wiring infrastructure better.

G.Hn HomeGrid powerline technology could appeal to apartment blocks where multiple powerline-based “wired no new wires” networks could exist

The G.Hn HomeGrid powerline network standards have been refined also to increase data transmission robustness where there are many powerline networks operated together. This would be, perhaps, a situation that takes place within a large multiple-premises building like an apartment block, shopping centre or office block and would suit today’s urban-design expectations of mixed-use multi-premises developments. Some people would also hold this true for a dense neighbourhood of terrace / townhouse, semi-detached or similar homes.

A G.Hn HomeGrid powerline network can co-exist with a HomePlug AV2 powerline network in the same building but isn’t directly compatible with each other. This is similar to first-generation HomePlug powerline networks operating alongside second-generation HomePlug AV / AV2 powerline networks.

Personally I see G.Hn HomeGrid being used to “take the powerline network further” to higher bandwidths, increased robustness, further distances (500 metres compared to 400 metres for HomePlug AV2 MIMO) and other future needs.

At the moment, Devolo are investing in this technology with their Magic series of powerline network products including some Wi-Fi access points and offering some of these devices to consumers.

But some other network-equipment vendors who have retail-market presence are offering at least a powerline-Ethernet adaptor that works to G.Hn HomeGrid standards as part of their powerline-network product ranges. It is a way for them to put a foot in the door for higher-bandwidth powerline network segments.

TV coaxial cable

Another medium type that is supported by G.Hn HomeGrid is the TV coaxial-cable infrastructure. This would be associated with cable TV, an outdoor TV antenna (aerial) or a satellite dish and there may be extra TV coaxial-cable sockets installed around the house so you can have additional TV sets or use an easily-moveable TV in other rooms.

The Multimedia Over Coax Alliance have created a standard for using TV coaxial-cable infrastructure. But G.Hn HomeGrid have seen intention in using this same medium for the same purpose and could be working it to higher capacities or increased robustness.

Phone line

Yet another medium type that is supported by this same standard is traditional telephone cabling. This was worked on by HomePNA but the HomeGrid Alliance took over that concern and embodied it in to the G.Hn HomeGrid standard.

This infrastructure would have come about for established homes where there are multiple phone sockets installed through the house’s lifetime. This would be due to the installation of extension phones or to allow one to move a corded phone between different locations easily before cordless phones became a cost-effective approach to flexible landline telephony.

Use profiles

The G.Hn standards implement two relevant use profile cases.

One is called HomeGrid which describes connecting network devices within the premises as part of a local area network.

The other is called Gigawire and is described as being for “access” connectivity. This is to connect between the network’s router WAN (Internet) connection and a modem that is used for providing Internet service. This use case encompasses fibre-copper setups within extant multiple-premises buildings used to provide Internet to each premises with the building. Or it can encompass a single-premises building where the modem associated with the Internet service is installed in an inconvenient location but the Wi-Fi router has to be installed in the centre of the premises for best results.

All of the media connectivity types such as powerline, phone line or TV coaxial cable are able to work in these different use profiles. But there is a question about whether the same medium type could be used for access or in-home connectivity at the same time.

Media-type agnostic approach

The G.Hn HomeGrid standard is being underscored as a media-layer-level standard for the “wired no-new-wires” networks with the goal to make it easier to bridge between different media types.

This could be about the arrival of lower-level bridge devices that link between the different media types with these devices not needing higher-level processing to do so. Most likely such devices will have the bridge functionality but also have a Cat5 Ethernet connection of some sort.

Further evolution of this standard

Currently this standard is being implemented as a “wired no-new-wires” approach to creating a multi-gigabit home network that has a bandwidth of 2.5Gbps or greater. It is to complement multi-Gigabit Ethernet and Wi-Fi 6/6E wireless network technology in raising your home network’s bandwidth making it fit for multi-gigabit broadband Internet services.

But there is further work needed to come about from G.Hn HomeGrid Forum for certain issues. For example, there will be a need to support VLAN network setups using the “wired no-new-wires” technologies. This would come in to play with routers that support a “guest network” or “community network” in addition to a primary network; or for VLANs that are used as a quality-of-service measure for VoIP or IPTV setups.

They would also have to examine the use of an access network and an in-premises network working on the same media bearer.

This could work with a fibre-optic extension setup that would normally use a G.Hn HomeGrid access network on a particular media type like phone line, power line or TV coaxial cable to bring the WAN (Internet) link from a garage or basement where the fibre-to-the-premises optical-network-terminal is installed to the living area where the home network router is installed. But the situation would change where that same basement or garage is purposed as a living space of some sort and a G.Hn HomeGrid in-premises LAN segment is to be created to make that space part of your home network.

Or there is the idea with a multiple-premises building where G.Hn HomeGrid technology is used for the in-building access network to each premises but there is a desire to extend a premise’s LAN or Wi-Fi to a common living area within the building.

Conclusion

The G.Hn HomeGrid and GigaWire standards are something that we have to watch and consider when it comes to “wired no-new-wires” network links for our home networks. In some cases, this technology may be about a “clean-slate” approach to your “wired no-new-wires” network segments.

My Comments

Devolo have become the first manufacture to exploit G.Hn HomeGrid “no-new-wires” technology in a retail setting. Here, they have exploited this in their Magic range of powerline-network devices that use this technology rather than HomePlug AV2 technology which their dLAN range of powerline network devices support.

Why is this so? There is continued development of G.Hn HomeGrid technology with on-premises powerline technology moving towards 2.4GHz bandwidth as well as improved operation for “simple yet secure” network setup. This includes improved performance for powerline-network setups within apartments and similar single-building many-premises developments. Another factor is that G.Hn HomeGrid technology isn’t dependent on a particular wired physical connection medium – it can work with traditional phone-line cabling or TV coaxial cabling.

This was thanks to the HomePNA phone-line-based home-network technology being absorbed by the HomeGrid Alliance and brought in to the ITU G.Hn standards.

But Devolo are taking this further by offering a G.Hn HomeGrid kit that uses either TV coaxial cabling or phone-line cabling to establish a Gigabit point-to-point link using no new wires. But who are they pitching this kit to?

In Germany at least, a significant number of fibre-to-the-premises installations for single-family homes or terrace-style (townhouse-style) homes have the optical-network terminal installed in the house’s basement. The householders then end up installing the home-network Wi-Fi broadband router downstairs in that basement. But they lose out on Wi-Fi performance thanks to the ground floor being made of dense materials that absorb radio waves associated with the Wi-Fi network segment.

A very similar installation scenario affecting some single-family houses with an attached garage is to have the optical network terminal for a fibre-to-the-premises setup installed in that garage. Some of these dwellings may have the wall between the garage and the house proper heavily insulated or thickened because the garage isn’t seen as living space and that wall may be built out of or insulated with material that attenuates radio waves.

The household then has to consider using a Wi-Fi range extender, a powerline-based Wi-Fi access point kit or a mesh network setup to improve the Wi-Fi reception in their living spaces upstairs. This may be good enough if the basement is being purposed as some form of living space like a games room or young adult child’s bedroom.

But this device is designed to connect to the Ethernet WAN connection between the ONT and the Wi-Fi broadband router and “extend” that so the router is installed in the living areas. As well, it is meant to use the telephone cabling or the coaxial cabling associated with a TV aerial, cable TV service or satellite dish.

Here, it is built on the assumption that a lot of the telephone wiring or the TV-aerial wiring is consolidated and exposed within the basement or garage, typically for the convenience of the installers. This will usually be the sign of a properly-installed TV or telephony setup where these spaces were taken advantage of rather than a series of splitters or junction boxes installed downstream to cater for ad-hoc installation of extra phone or TV points.

They offer a similar device that uses G.Hn HomeGrid powerline connectivity for this same purpose. This device, known as the Fiber Connect, isn’t compatible with the HomePlug powerline connectivity standards and is focused as a point-to-point device

At the moment, the Devolo Giga Bridge device is focused on a point-to-point setup primarily for extending the Ethernet (WAN) connection further out. As Devolo works on implementing the G.Hn HomeGrid standard further for home networks, it could be about developing it to work with their Magic G.Hn powerline implementation or implementing it as a multipoint setup for phone-line or TV coaxial setups.

What is showing up here is that Devolo are putting their faith in the G.Hn HomeGrid home-network approach especially in the retail and direct-to-consumer marketspace. This is compared to only marketing devices based on that technology to ISPs, telco and professional installers who supply and install these devices.

Wi-Fi 7 is coming, and Intel makes it sound great | Network World

My Comments

Wi-Fi 6 is already established as a wireless network standard and this is being taken to  Wave 2 with some incremental improvements.

But Wi-Fi 7, is to be coming soon and is actually the IEEE 802.11be wireless-network standard which is expected to be the follow-on to Wi-Fi 6.

It is expected to offer 320MHz bandwidth for each RF channel and provide a theoretical link-layer throughput of 96.1Gbps. As well, a Wi-Fi 7 wireless network segment is expected to be able to work on the 2.4 GHz, 5GHz and 6GHz radio bands.

This will support multi-link operation where network devices can work on multiple channels across multiple wavebands at once. This allows for a “fat pipe” that carries more data along with reduced latency (important for games or videocalls) and increased operational robustness. This latter benefit is provided by allowing particular data to use particular channels.

Wi-Fi 7 is to lead wireless network segments towards multiple-gigabit networking. As well, Wi-Fi 7 will have integrated support for Wireless Time-Sensitive Networking which assures synchronous delivery of data to multiple endpoints with use cases being multichannel sound, multi-camera setups or robotics and industrial automation.

This technology will take time to come to fruition even if it is “cemented in stone” by the IEEE now. There will be the need to see the necessary silicon being made available to client-device and network-infrastructure manufacturers so they cam implement it in their own products. This will also include the requirement to to see power-efficient Wi-Fi 7 client-device silicon implementations before a significant number of portable devices come with this technology.

Then the client and network infrastructure devices will appear but be at that price point and marketing position that only appeals to early-adopters who will pay a premium to have the latest and the greatest. But a few years later will see Wi-Fi 7 be a mature wireless-network technology.

But this will come in to its own with ubiquitous ultra-high-definition TV, augmented and virtual reality along with computing environments pitched towards gamers, creators and mobile-workstation users.
