EasyMesh R2 Will Intelligently Manage Your Home Wi-Fi (Press Release)

Wi-Fi defines a new standard for distributed wireless netowrks

Telstra is the first telco to supply home-network hardware that supports Wi-Fi EasyMesh

My Comments

The Wi-Fi EasyMesh standard that facilitates a distributed-Wi-Fi network without the need to have all equipment from the same equipment or chipset vendor has undergone a major revision. This revision, known as Release 2, is intended to improve network management, adaptability and security as well as supporting proper VLAN / multiple-ESSID operations that is especially required with guest, hotspot and community Wi-Fi applications.

What will Release 2 offer and how will it improve Wi-Fi EasyMesh?

Standardisation of diagnostic information sharing across the network

Wi-Fi EasyMesh Release 2 will make use of the Wi-Fi Data Elements to allow the Controller device to collect statistics and diagnostic information from each access point in a uniform manner. It doesn’t matter which vendors the different equipment in the EasyMesh-compliant Wi-Fi network come from.

Here, it will benefit companies like telcos, ISPs or IT support contractors in identifying where the weaknesses are in a Wi-Fi network that they provide support for. For those of us who support our own networks, we can use the tools provided with the main Wi-Fi router to identify what is going wrong with the setup.

Improved Wi-Fi radio channel management to assure service continuity

The second release of Wi-Fi EasyMesh will offer improved channel management and auto-tuning of the access point radio transceivers. This will make sure that the Wi-Fi network is able to adapt to new changes such as newer networks being setup nearby.

It wll also be about implementing DFS to make sure that Wi-Fi networks that use the 5 GHz bands are working as good neighbours to radar installations like weather radar located nearby and using those bands. This will happen not just on initial setup of any Wi-Fi EasyMesh node but continually which will be of concern when, for example, a local meteorological authority installs a new radar-based weather station in your neighbourhood.

Increased data security for the wireless backhaul

The wireless backhaul for a Wi-Fi EasyMesh R2 network will be more secure through the use of current Wi-Fi data-security protocols like Simultaneous Authentication Of Equals. There will even be the ability to support robust authentication mechanisms and newer stronger cryptographic protocols.

It is seen as necessary because the wireless backhaul is used as the main artery to convey all the network’s traffic between the access points and the main “edge” router. This can appeal to anyone who wishes to snoop on a user’s Internet traffic; and also conveys the fact that the Wi-Fi EasyMesh network is effectively a single LAN segment where all the data for Wi-Fi client devices moves around.

Secure wireless-backhaul support for VLAN-separated data traffic

Increasingly, home-network equipment is implementing VLAN technology for a range of reasons. One of these is to facilitate triple-play services and assure quality-of-service for IPTV and IP-based telephony services offered by the telco or ISP. The other is to facilitate guest/hotspot and community networks that use the same Internet service connection but are effectively isolated from the main home or small-business network.

This release of the Wi-Fi EasyMesh standard will support these setups by configuring each node to support the multiple virtual networks including their own separate extended-service-set configurations. The wireless backhaul will also be set up to create separate “traffic lanes” for each logical network that are securely isolated from each other.

Enhanced client steering

There will be the ability to steer client devices between access points, wavebands or channels to prevent one or more of these resources from being overloaded.

For example, it could be feasible to have dual-band client devices like most laptops, tablets and smartphones work on the 5GHz band if they are dealing with multimedia while keeping the 2.4GHz band for low-traffic needs and single-band devices. Similarly, if a client device “sees” two access points equally, it could be made to use whichever one isn’t being overloaded or has the batter throughput.

Of course, the enhanced client steering will provide a seamless roaming experience similar to what happens with the cellular-based mobile telephony/broadband networks that power our smartphones. This is a feature that is of importance with any device that is highly-portable in nature like a smartphone, tablet or laptop.

Key issues that may surface with Wi-Fi EasyMesh

A key issue that may crop up with Wi-Fi EasyMesh is supporting the use of multiple backhauls across the same network and offering “true-mesh” operation rather than hub-and-spoke operation. Here, it could be about opening up options for load-balancing and increased throughput for the backhaul or providing fault-tolerance for the network.

As well, the idea of a wired backhaul implementing IEEE 1905.1 small-network management technology has to be kept in scope when designing Wi-Fi EasyMesh devices or promoting and implementing this standard. This is more so to encourage HomePlug AV2 or G.Hn powerline-network technology as a companion “wired no-new-wires” backhaul approach for deploying satellite nodes in areas where a wireless backhaul may not perform to expectation but it would be costly or unfeasible to pull Ethernet cable across the premises.

How can this be deployed with existing Wi-Fi EasyMesh networks

There are measures built in to the Release 2 specifications to permit backward compatibility with legacy Wi-Fi EasyMesh network-infrastructure devices like the Telstra Smart Modem Generation 2 that exist in the network.

As well, some vendors are taking the approach of implementing the Release 2 functionality as software form. This makes it feasible for them to bake this functionality in to a firmware update for an existing EasyMesh-compliant router or access point without the need to worry about the device’s underlying hardware.

Conclusion

I see Wi-Fi EasyMesh Release 2 as offering the chance for Wi-Fi EasyMesh to mature as a standard for distributed-Wi-Fi setups within the home and small-business user space. This release may even make it affordable for small businesses to dabble with a basic managed distributed-Wi-Fi setup due to not being required to stay with a particular vendor/

Linksys Expands MAX-STREAM Mesh Router Portfolio With Its Most Affordable WiFi 6 Solution (Press Release)

MAX-Stream Mesh Wi-Fi 6 Router (MR7350) – Product Page

My Comments

Two companies have pushed Wi-Fi routers which are about bringing Wi-Fi 6 (802.11ax) technology within the reach of everyone who is establishing a home network based around a fixed broadband Internet service. This is being drawn out of necessity thanks to smartphones, tahlets and laptops released through this year being equipped with Wi-Fi 6 connectivity.

The first of these is Deutsche Telekom who have poised to release in to the German market a unit that will be typically supplied to a household signing up for fixed broadband Internet offered by that telco. This unit, known as the Speedport Smart 4 Plus is equipped with Wi-Fi 6 and will be about providing this technology in a turnkey manner to a home Internet service customer. It is ready to be launched at the IFA 2020 trade fair at Berlin in September.

The other is Linksys who have offered the MR7350 broadband router through retail channels for USD$149. It is rated as an AX1800 unit which will provide an average throughput for a Wi-Fi 6 router. But it is able to be part of Linksys’s Intellignent Mesh distributed-Wi-Fi setup, thus allowing you to expand your network’s Wi-Fi range when teamed with a compatible Linksys Wi-Fi router.

Engadget’s review described the Linksys MR7350 router as being fit for starting a Wi-Fi 6 network to cover an average-sized apartment or townhome unit. It can also be seen as an affordable infill access point for a Linksys Intelligent Mesh distributed-Wi-Fi setup, especially if you decide to put a better router from that product range as the Internet edge of your home network.

But what I am pleased about these devices is that they are an effort to bring Wi-Fi 6 (802.11ax) technology in to most home networks. These efforts may be continued on by other carriers, and home-network equipment manufacturers.

Wi-Fi 6 is here for certain

My Comments

The Wi-Fi Alliance have started this week to certify devices as to whether they are compliant to the new Wi-Fi 6 (802.11ax) wireless-network standard. This effectively means that this technology will be ready for prime time.

But what will it offer?

NETGEAR Orbi with Wi-Fi 6 press picture courtesy of NETGEAR

NETGEAR Orbi Wi-Fi 6 – the first distributed Wi-Fi setup with Wi-Fi 6 technology

Wi-Fi 6 will offer a theoretical data throughput of 10Gbps which is 30% faster than Wi-Fi 5 setups. There will also be the ability for one access point or route to support many Wi-Fi client devices at once thus preventing that device from being “oversubscribed” and underperforming when many devices come on board. It answers a common situation where a small network that is typically served by one Wi-Fi router ends up having to support multiple Wi-Fi client devices like laptops, smartphones, smart speakers of the Amazon Echo kind, and set-top devices for streaming video. It is facilitated through the use of a higher-capacity MU-MIMO technology.

In addition, the Wi-Fi 6 routers and access points implement OFDMA technology to share channels and use them efficiently. It will mean that multiple Wi-Fi 6 networks can coexist without underperforming which will be of benefit for apartment dwellers or trade shows and conferences where multiple Wi-Fi networks are expected to coexist.

There is also the targeted wake time feature to “schedule” use of a Wi-Fi 6 network by battery-operated devices. This will allow them to know when to send data updates to the network especially if they don’t change status often, which will benefit “Internet-of-Things” devices where there is the desire to run them for a long time on commodity batteries.

A requirement that will be placed on Wi-Fi 6 devices is to support WPA3 security for their network security standard. It is to improve the expectation upon these devices for a secure Wi-Fi network.

At the moment, routers and access points based on Wi-Fi 6 will be positioned at the premium end of the market and be typically targeted towards “be first with the latest” early adopters. But over the next year or two, the market will settle out with devices at more affordable price points.

Premium smartphones, tablets and laptops that are being redesigned from the ground up with new silicon will end up with Wi-Fi 6 network interface chipsets. This will apply to the Samsung Galaxy S10 family, computers based on Intel Ice Lake CPUs and the Apple iPhone 11 family. As well, some network-hardware vendors are offering add-on Wi-Fi 6 network adaptors that plug in to your laptop computer’s USB port to enable it for the new technology.

At the moment, if you are running a network with a Wi-Fi 5 access point or router that is serving devices based on Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac) technology, you don’t need to upgrade the access point or router yet.

But if you have to replace that device due to the existing unit dying or you intend to set up a new Wi-Fi network, it may be worth investigating the purchase of network infrastructure equipment based on Wi-Fi 6.

You will also find that each device will be provided with “best case” performance based on its technology. This means that if you install a Wi-Fi 6 access point or router on your network then subsequently sign a subsidised-equipment post-paid service contract for a smartphone with Wi-Fi 6 technology built in, the smartphone will work to Wi-Fi 6 levels while your laptop that supports Wi-Fi 5 technology works to that prior technology without impeding your smartphone’s Wi-Fi 6 functionality.

If you bought one of the earlier Wi-Fi 6 routers or distributed Wi-Fi setups which works to pre-certification standards, check your manufacturer’s site for any new firmware that will have the device working to the current specifications and upload it to your device.

Wi-Fi 6 wireless networks will become a major boon for evolving local-area networks towards higher capacity and faster throughput on wireless segments.

6GHz Wi-Fi technology moving towards room-by-room Gigabit Wi-Fi

Distributed Wi-Fi setups like this NETGEAR Orbi will be heading towards the Gigabit Wi-Fi goal on the 6GHz waveband

ARRIS: How 6 GHz Wi-Fi will revolutionise the connected home | Wi-Fi Now

My Comments

ARRIS who make home-network equipment for the American market, are pushing the idea that the 6 GHz Wi-Fi network is a major evolution for the home network.

This is coming about due to various national government departments who have oversight over radiocommunications use within their jurisdiction working on regulatory instruments to open up unlicensed low-power indoor use of the 6 GHz radio waveband. Such regulation is expected to be passed by the FCC in the US by mid-year 2020 and OFCOM in the UK by 2021 with other jurisdictions to follow suit over the next few years.

It will open up seven new 160MHz channels for the Wi-Fi 6 technology with the feasibility to open up a Gigabit Wi-Fi network. This is expected to lead to the evolution of the self-configuring distributed Wi-Fi setup with a Gigabit Wi-Fi backbone plus each access point offering a 160MHz Wi-Fi 6 channel alongside support for low-power narrower-bandwidth 2.4GHz and 5GHz channels for legacy equipment.

There will be the implementation of Wi-Fi EasyMesh and Wi-Fi EasyConnect standards to permit secure setup and an open-frame heterogenous distributed-wireless network.

One limitation I do see confronting this ideal that Arris put forward is the short-wavelength Wi-Fi backbone which can be a hindrance with certain building materials and construction approaches like double-brick walls. There will also be the requirement to run many access points to make sure the average home is covered properly. Here, the wired backbone whether “new wires”  like Ethernet or “no new wires” like HomePlug AV2 powerline or MoCA TV-antenna coaxial still has toe be considered for a multiple-access-point network.

ARRIS was even positioning for the evolution of the distributed Wi-Fi network to have each room with its own access-point node capable of yielding Gigabit bandwidth. They also put forward ideas like having these access points mounted on the ceiling. But I would also prefer the idea of a normally-sessile endpoint device like a network printer, Amazon-Echo-style smart speaker or a smart TV being its own access point that is part of the distributed Wi-Fi network. It then avoids the need to equip a room with an extra access point if you are intending to have this kind of device in that room.

The use of Wi-Fi 6 technologies will also be about working with environments that are congested as far as Wi-Fi wireless networking is concerned. These environments like multiple-premises buildings, airports or hotels are likely to have many Wi-Fi devices operating on many Wi-Fi networks which with prior technologies leads to poor performance especially on the throughput and latency side.

It may have to take a few years for the Wi-Fi wireless network to hit the Gigabit throughput mark as the 6 GHz band opens up and more access-point and client devices come on the market.

20 Years of Wi-Fi wireless

20 Years of Wi-Fi (Press Release)

My Comments

“Hey, what’s the Wi-Fi password here?”. This is a very common question around the home as guests want to come on to your home network during their long-term visit to your home. Or one asks the barista or waiter at the cafe “Do you have Wi-Fi here?” with a view to some free Internet use in mind.

“What’s the Wi-Fi password?”

It is brought about by Wi-Fi wireless-network technology that has become a major lifestyle changer over the last 20 years. This has been propelled in the early 2000s with Intel advancing their Centrino Wi-Fi network-interface chipset which put forward the idea of highly-portable computing.

The laptop like this Dell XPS 13 – part of the Wi-Fi lifestyle

The laptop computer, mobile-platform tablet and smartphone benefited from Wi-Fi due to their inherently-portable nature. This effectively allowed for “anywhere anytime” online work and play lifestyle including using that iPad or smartphone as a second screen while watching TV. Let’s not forget the use of Internet radios, network-based multiroom audio setups and those smart speakers answering you when you speak to them.

“Do you have free Wi-Fi here?”

Over the years there has been incremental improvements in bandwidth, security and quality-of-service for Wi-Fi networks both in the home and the office. Just lately, we are seeing home networks equipped with distributed Wi-Fi setups where there are multiple access-point devices working with a wired or wireless backhaul. This is to assure full coverage of our homes with Wi-Fi wireless signals, especially as we face different floorplans and building-material types that may not assure this kind of coverage.

But from this year onwards, the new Wi-Fi network will be based on WI-Fi 6 (802.11ax) technology and implement WPA3-grade security. There will also be the idea of opening up the 6GHz wavebands around the world to Wi-Fi wireless-network traffic, along with having support for Internet-of-Things applications.

The Wi-Fi router – part of every household

The public-access Wi-Fi networks will be more about simple but secure login and usage experiences thanks to Wi-Fi Passpoint. This will include simplified roaming between multiple Wi-Fi public-access hotspot networks, whether this is based on business relationships or not. It will also lead to telcos using Wi-Fi networks as a method to facilitate complementary coverage for their mobile-broadband networks whether they use current technology or the new 5G technology.

What needs to happen for Wi-Fi is to see work take place regarding high-efficiency chipsets for Internet-of-Things applications where such devices will be required to run on a small number of commodity batteries for a long time. One requirement I would like to see for public-access Wi-Fi is the ability to create user-defined “secure device clusters” that allow devices in that cluster to discover each other across the same public-access network but other devices outside of the cluster can’t discover them.

So happy 20th Anniversary to the network technology that has effectively changed our online lifestyle – the Wi-Fi wireless network.

WPA3-Personal security–What does this mean for your Wi-Fi network

Article

Telstra Gateway Frontier modem router press picture courtesy of Telstra

Expect the next-generation Wi-Fi network to have WPA3 security

What is WPA3? And some gotchas to watch out for in this Wi-Fi security upgrade | Network World

My Comments

Over the next few years, Wi-Fi routers, access points and client devices like computers and smartphones will be supporting WPA3 as a media-specific network security protocol.

At the moment, I will be focusing on the WPA3-Personal variant which is relevant to small networks like the typical home or small-business network. This kind of network security is also implemented in an increasing number of venue-based public-access networks in order to allow the venue owner to protect and authenticate the network and preserve its role as an amenity for the venue’s customers.

The WPA3-Personal network security protocol has the same method of operation as for a WPA2-Personal network. This is using a “Wi-Fi password” commonly known across all access points and client devices that use the network segment.

But it describes this “Wi-Fi password” as Simultaneous Authentication Of Equals rather than the previous Pre-Shared Key used in previous WPA-Personal implementations. It also affects how this “Wi-Fi password” is represented and encrypted in order to protect it against an off-site brute-force cracking attempt.

As well, each connection between the client device and the access point is encrypted in a manner unique to that connection.

The initial onboarding process will be typically based on the traditional password-entry method. But it will also implement Wi-Fi EasyConnect which uses a QR code or WPS-based push-button setup.

The Wi-Fi WPA3 security protocol may take years to become mature while a secure surefire codebase for client-side and access-point-side implementations is worked out. The initial codebase was found to have software weaknesses in the early Personal-setup implementation and is being debugged now.

A question that will be raised is whether an upgrade to WPA3 security will require new hardware for either the client device or the access point or if this can be performed using revised firmware that has the necessary software code. This may depend on whether the hardware uses a purely software-defined approach for managing its functionality.

There will be situations that will take place regarding existing equipment and WPA3-capable equipment. Here, a WPA3 client like a smartphone can work with an existing WPA2-compliant Wi-Fi network segment but not have the full benefits. Similarly, a WPA3-capable Wi-Fi network segment will need to be operated in a “transition mode” to allow existing WPA2-compliant client devices to connect. Again, this doesn’t provide all the benefits of a Wi-Fi network segment secure to WPA3 standards.

You can also work around this limitation by implementing two Wi-Fi network segments that have separate ESSIDs. One of these could be configured to work the current WPA2-Personal standard while the other is set up purely for WPA3-Personal. This practice may come in to its own if you have a Wi-Fi network using the latest standards while you maintain another using tried-and-trusted standards.

LEADING A NEW ERA OF WI-FI, NETGEAR ANNOUNCES ORBI MESH WI-FI SYSTEM USING WI-FI 6 SPECIFICALLY DESIGNED FOR THE GIGABIT INTERNET HOME (Press Release)

Product Page

My Comments

As Wi-Fi 6 (802.11ax) wireless networking comes to the fore, there will be a desire to see distributed-wireless-network systems that support this technology. Here it’s about being able to support many Wi-Fi client devices like laptops, tablets and smartphones along with devices that are designed “Wi-Fi first” including smart-home devices.

NETGEAR have started to refresh the Orbi distributed Wi-Fi system by making a new version that supports this new technology as part of the product lineup they are premiering in Las Vegas at this year’s Consumer Electronics Show. It uses the separate radio backhaul that their Orbi system is know for, thus avoiding a dent in performance that can be brought about with systems that use the main “fronthaul” Wi-Fi segment for their backbone data transfer.

But it uses four data streams across the dedicated Wi-Fi 6 backhaul to allow high-speed high-capacity data transfer. It is in addition to four concurrent data streams on the 2.4GHz band and four concurrent data streams on the 5GHZ band for the client devices to use. The system is powered by Qualcomn networking system-on-chip silicon that allows for the higher data throughput.

It is expected to appear during the second half of 2019, primarily as an updated take of the RBK50 wide-coverage devices. A question that will perplex those of us who have an Orbi distributed-Wi-Fi setup is whether the existing Orbi equipment will work with the newer Wi-Fi 6 Orbi devices.

This is more so where smaller or specialised Orbi satellite modules like the RBS50 Orbi Outdoor Satellite unit or the Orbi Voice which is a combination of a satellite unit and Amazon-Alexa-driven smart speaker are part of your Orbi setup. Or you like the idea of “pushing down” existing equipment to secondary purposes so you get more value out of the equipment you own.

What is being highlighted is the idea of using Wi-Fi 6 as a future-proof approach for wireless local networking, including distributed- Wi-FI setups.

Staff panic buttons to drive networks to handle the Internet of Things

Article

Ekahau Wi-Fi Pager Tag panic button

Emergency-alert buttons like this Ekahau Wi-Fi name-tag panic-button setup will be influencing network architecture for the Internet Of Things

The Hotel Panic Button Could Redefine Hospitality Networking | IoT World Today

My Comments

In some workplaces where staff work alone at night or other times where they are in danger, portable emergency-call buttons are often used. Initially they were the same size as an older garage-door opener but they are becoming the size of a pendant, badge or fob. As well, rather than these devices lighting up a separate alert panel, they light up a message or “throw up” a map with an indicator on a regular computer running building-security software to show where the danger is.

Initially, they were being positioned for very-high-risk workplaces like psychiatric care or the justice and allied settings. But other workplaces where staff work alone are seeing these devices as an important safety measure, usually due to various occupational health-and-safety requirements.

For example, hotels in the USA are moving towards having Housekeeping staff use these devices in response to workplace agreements, industry safe-work safe-premises initiatives or city-based legal requirements. But these systems are being required to work in conjunction with the Wi-Fi networks used by staff and guests for business and personal data transfer.

A device of the kind that I had covered previously on HomeNetworking01.info was the Ekahau Real Time Location System. This was a pendant-style “panic-button” device, known as the T301BD Pager Tag which had an integrated display and call button. It also had a setup that if the tag was pulled at the nexkstrap, it would initiate an emergency response.  I also wrote an article about these Ekahau devices being deployed in a psychiatric hospital as a staff emergency-alert setup in order to describe Wi-Fi serving a security/safety use case with the home network.

This application is being seen as a driver for other “Internet-of-Things” and smart-building technologies in this usage case, such as online access-control systems, energy management or custom experiences for guests. As I have said before when talking about what the smart lock will offer, the hotel may be seen as a place where most of us may deal with or experience one or more of the smart-building technologies. Also I see these places existing as a proving ground for these technologies in front of many householders or small-business owners who will be managing their own IT setups.

One of the issues being drummed up in this article is quality-of-service for the Internet Of Things whereupon the device must be able to send a signal from anywhere on the premises with receiving endpoints receiving this signal with no delay. It will become an issue as the packet-driven technologies like the Internet replace traditional circuit-based technologies like telephone or 2-way radio for signalling or machine-to-machine communication.

The hotel application is based around the use of multiple access points, typically to provide consistent Wi-Fi service for staff and guests. Such a setup is about making sure that staff and guests aren’t out of range of the property’s Wi-Fi network and the same quality of service for all network and Internet use cases is consistent throughout the building. Here, concepts like mesh-driven Wi-Fi, adaptive-antenna approaches, load-balancing and smart smooth roaming are effectively rolled in to the design of these networks.

Wi-Fi access points in the smart-building network will also be expected to serve as bridges between IP-based networks and non-IP “Internet-of-Things” networks like Bluetooth Low Energy (Bluetooth Smart), Zigbee, Z-Wave or DECT-ULE. These latter networks are pushed towards this application class due to the fact that they are designed to support very long battery runtimes on commodity batteries like AA Duracells or coin-style watch batteries. There will be an emphasis on localised bridging and the IP-network-as-backbone to provide better localisation and efficient operation.

These systems are being driven towards single-screen property-specific dashboards where you can see the information regarding the premises “at a glance”. I would reckon that operating-system-native applications and, perhaps, Progressive Web App versions will also be required to use operating-system-specific features like notification-panels to improve their utility factor in this context.

As far as the home network is concerned, I do see most of these technological concepts being rolled out to the smart home with an expectation to provide a similar service for householders and small businesses. This is more important as ISPs in competitive markets see the “Internet of Things” and improved Wi-Fi as a product differentiator.

The use of multiple Wi-Fi access points to cover an average home being made real for a home network thanks to HomePlug wireless access points, Wi-Fi range extenders and distributed-Wi-Fi systems that will bring this kind of localised Wi-Fi to the smart home. Typically this is to rectify Wi-Fi coverage shortcomings that crop up in particular architecture scenarios like multi-storey / split-level premises and use of building materials and furniture that limit RF throughput. It is also brought about thanks to the use of higher-frequency wavebands like 5GHz as Wi-Fi network wavebands.

There will be an industry expectation to require access points and similar devices to provide this kind of “open-bridging” for Internet-of-Things networks. This is more so where battery-operated sensor or controller devices like thermostatic radiator valves and smart locks will rely on “low-power” approaches including the use of Zigbee, Z-Wave or similar network technology.

It will also be driven typically by carrier-supplied routers that have home-automation controller functionality which would work with the carrier’s or ISP’s home-automation and security services.

To the same extent, it may require “smart-home / building-automation” networks to support the use of IP-based transports like Wi-Fi, HomePlug and Ethernet as an alternative backhaul in addition to their meshing or similar approaches these technologies offer to extend their coverage.

In some cases, it may be about Zigbee / Z-Wave setups with very few devices located at each end of the house or with devices that can’t always be “in the mesh” for these systems due to them entering a “sleep mode” due to inactivity, or there could be the usual RF difficulties that can plague Wi-Fi networks affecting these technologies.

DECT-ULE, based on the DECT cordless-phone technology and is being championed by some European technology names, doesn’t support meshing at all and IP-based bridging and backhauls could work as a way to extend its coverage.

Such situation may be rectified by access points that use a wired backbone like Ethernet or HomePlug powerline.

In the context of the staff panic button use-case, it will roll out to the home network as part of a variety of applications. The common application that will come about will be to allow the elderly, disabled people, convalescents and the like who need continual medical care to live at home independently or with support from people assuming a carer role.

This will be driven by the “ageing at home” principle and similar agendas that are being driven by the fact that people born during the post-war baby boom are becoming older as well as the rise of increased personal lifespans.

Similarly, this application may also be underscored as a security measure for those of us who are concerned about our loved ones being home alone in a high-risk environment. This is more so in neighbourhoods where the risk of a violent crime being committed is very strong.

But I would see this concept work beyond these use cases. For example, a UK / European central-heating system that is set up with each radiator equipped with a “smart” thermostatic radiator valve that is tied in with the smart-home system. Or the use of many different control surfaces to manage lighting, comfort and home-entertainment through the connected home. This is something that will rise up as most of us take on the concept of the smart home as the technology standardises and becomes more affordable.

What is being highlighted is the requirement for high quality-of-service when it comes to sending “Internet-of-Things” signalling or control data as our networks become more congested with more gadgets. Similarly, it is about being able to use IP-based network technology as a backhaul for non-IP network data that is part of the Internet-of-Things but providing the right kind of routing to assure proper coverage and quality-of-service.

My Comments

There is some hype being driven by organisations defending the 5G mobile broadband and Wi-Fi wireless LAN technologies about their technology being the only one for our connected lives.

Some existing devices use 5G mobile-broadband technology but connect to endpoint devices like mobile phones using Wi-Fi. Initially they are routers being deployed by mobile carriers as a proof of concept or for network trials while AT&T were offering a “Mi-Fi” for retail sale in the USA that implements 5G technology. At the moment, 5G hasn’t been rolled out in the form of a smartphone or a mobile-broadband modem that is integrated in or connected by USB to a host computer.

Both Wi-Fi 5 (802.11ac and prior technologies) and 4G LTE mobile broadband have seen widespread deployment with each technology being seen by mobile users as offering a complementary role. Networks and equipment running the newer technologies (5G and Wi-Fi 6) will be backward compatible and offer a best-case approach to this compatibility. That is if both the network and end-user equipment run the same technology, the user gains the most benefit from what the new technology offers.

It has been identified that both technologies at their latest specification can complement each other. Here, 5G will earn its keep in the outdoors and in a mobile context while the Wi-Fi 6 (802.11ax) technology will earn its keep indoors. This is although public-access Wi-Fi networks will be seen by mobile carriers as a cost-effective data-offload tool.

Wi-Fi also has supporting technologies like WiGig and Wi-Fi HaLow. The former one will match 5G for speed but uses a short range equivalent to an ordinary room in the house, while the latter benefits from long range and power efficiency but doesn’t have the speed. Wi-Fi HaLow will then end up in the smart-home, smart-building, connected-car and smart-city application spaces where data throughput isn’t all that necessary. This is while WiGig will end up with virtual reality, augmented reality, 4G video and other bandwidth-intensive applications.

Then there is also the kind of spectrum available for each technology. Wi-Fi technologies primarily rely on unlicensed radio spectrum which makes them popular for households and businesses to deploy. It is in contrast to 5G which, like other cellular mobile telecommunications technologies, relies on licensed radio spectrum which the mobile carrier has to deal with the national radiocommunications authority organise and purchase a license to use.

There is also a trend regarding wireless-network equipment design where there is a software-defined approach towards the media-level components. This is facilitated with small-footprint high-capability computing power and can allow the same piece of equipment to honour newer standards.

Another factor that is never raised is the concept of the local network where data can be transferred between co-located devices at the same premises. 5G is really positioned as a wireless “last mile” setup for providing telecommunications and Internet service to the end-user. This is while Wi-Fi is intended primarily to work as a local network but is used to distribute a single broadband service to multiple endpoint devices.

What really is now seen is that the new 5G mobile broadband and Wi-Fi 6 (802.11ax) LAN technologies can complement each other in a horses-for-courses manner.

My Comments

The Wi-Fi Alliance have decided to adopt a new nonenclature for the different main standards that Wi-Fi networks support. This  is in stark contrast to referring to each standard by its IEEE reference which can sound confusing.

It will be used in product marketing material and specifications sheets to refer to the effective “generation” that the router / access point or client device will support so one can know what is the expected “best” capability offered by that device.

But the device’s operating system or firmware will be able to indicate on devices with some sort of dynamic visual user interface the “generation number” the network connection will support. In the case of client devices like computers or smartphones, this will be to indicate the “best available” network expectation for the current connection.

Similarly, people and companies who provide a public-access Wi-Fi network can reference the kind of performance expected out of this network by using the “generation number” indicating what technology it would support. It could be use as a means to gauge the network’s suitability for handling peak loads such as, for example, a transit station during peak hours or a fully-occupied hotel.

A question that will come up will be is what way will the device indicate whether it is a simultaneous multi-band device or how many MIMO streams it concurrently runs. This will be of importance with Wi-Fi 4 / 5 / 6 (802.11n/ac/ax) devices that can work on two or more bands and have MIMO abilities but at differing levels of capability and performance.

Classic examples of this could be some low-cost access points and Wi-Fi extenders capable of working to dual-stream 802.11n on the 2.4GHz band known as N300 devices or mobile devices working on single-stream or dual-stream MIMO chipsets as part of battery conservation.

On this site going forward, I will be using the new “Wi-Fi generation number” along with the IEEE standard reference for describing the Wi-Fi network technology offered by a network device. It will also apply to describing minimum Wi-Fi standards particular to a networking situation that I write about.

For example, I may describe the Dell XPS 13’s Wi-Fi abilities as Wi-Fi 5 (802.11ac) dual-stream to reflect the effective generation Wi-Fi supported by that Ultrabook.

At least this new nonenclature will be a barometer to indicate whether a Wi-Fi network is running new technology to allow it to perform properly.
