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.

Recently, at this year’s Consumer Electronics Show in Las Vegas, some of the major home-network hardware providers offered distributed Wi-Fi network setups which provide a simplified method to improve your home network’s Wi-Fi wireless coverage.

These have been offered either in a mesh-based setup or as a “router and extender” setup with simplified setup and operation procedures. The mesh setup creates a wireless backbone mesh between each of the “nodes” in such a way that any node can obtain a strong high-throughput signal from two other nodes and there is a failover process where if one node is out-of-action, other nodes can keep the coverage going. On the other hand, a “router and extender” setup works like most of the wireless extenders on the market but implements a simplified setup and roaming experience between the router and extenders.

Some of the distributed Wi-Fi network setups also allow for the use of a wired backbone which can cater for difficult wireless-network situations, multiple building setups or even as a robust high-throughput option.

There has been a need for these setups thanks to increased streaming of video content like Netflix along with heavy use of highly-portable computer devices like laptops, tablets and smartphones. But the typical Wi-Fi setup ends up being compromised by many different situations such as routers being installed at one end of the premises, the use of dense or metallic building materials in our houses and apartments or even “white goods” or metallic furniture like filing cabinets installed in a cluster against interior walls. As well, the existence of multiple Wi-Fi networks in a neighbourhood can make things works.

But there are some telcos, cable-TV providers and Internet service providers are offering distributed wireless setups as an extra-cost option for all of their customers, and / or as “part of the package” for their top-shelf packages. This kind of service is also of interest to other ISPs who are wanting to offer that more value to their customers, and is in response to complaints that customers aren’t benefiting from the headline or contracted bandwidth at their devices especially when they are using the Wi-Fi wireless network.

Examples of this are Singtel in Singapore, and Midco (Midcontinent Communications) in the USA are offering a distributed Wi-FI system as their “premium Wi-Fi” option offered as an extra-cost option while Waoo in Denmark are offering it at no extra cost to subscribers who take up their premium Internet packages that they offer with it available for extra cost for people who subscribe to the cheaper packages.

Here, the distributed Wi-Fi setup would be part of the modem-router normally offered as customer-premises equipment with it being managed and serviced by the ISP.  Some of these setups also have TV set-top boxes that also work as access points or as part of the mesh ecosystem, typically using a wired (MoCA, HomePlug AV500) or wireless backhaul. There may also be the use of dedicated access-point nodes around the premises to provide the extra reach to the other areas.

The ISPs are, at the moment, seeing this as leading towards increased customer satisfaction due to the increased stability and throughput realised at the end devices. It is also seen as being equivalent to cable-TV services where customers rent a PVR-based set-top box, because such customers see this as being better value for money therefore less likely to walk away from the service.

Another router answers the needs for a secure home network

eero: A Mesh WiFi Router Built for Security (Product Review) | Krebs On Security

My Comments

A common issue raised in relation to home-network routers is that they aren’t really designed for security. It applies more to the equipment that is sold through the popular retail locations like the electronics chains.

This is due to issues like firmware that isn’t always kept up to date along with an insecure “out-of-box” management-console login experience. The latter situation manifests typically in the form of a default username and password that is common across a product range rather than unique to each device.

The eero router which is effectively a Wi-Fi mesh system has answered these issues courtesy of the following: firmware that is updated automatically and a secure-setup routine based around an enabling code sent to your phone. The former method has been practised by AVM with their latest firmware for the Fritz!Box routers with these devices automatically updating. The latter method has been practised through the use of a mobile-platform app where you enter your name, email address and mobile phone number. This requires you to receive a one-time password from your smartphone by SMS. You enter this to the mobile app before you determine your home network’s ESSID and passphrase.

This kind of login experience for the management Web page could be very similar to a well-bred two-factor authentication routine that comes in to play for some online services whenever you add another device or, in some cases, as you log in. Here, the FIDO U2F standard or support for Google Authenticator could be implemented in a router to permit secure login to the management page.

As for Wi-FI implementation, this router implements a proprietary mesh technology with each extender implementing separate radio transceivers for both the backhaul link and the client-side link. This allows for full bandwidth to be served to the Wi-Fi client devices. Each router device also has two Ethernet ports with one of those being configured for WAN (Internet) connection. Personally, I would like to see both ports switch to LAN mode on an eero router if it is serving as a repeater. This would earn its place with video peripherals, printers or desktop computers.

What I see of this is a step in the right direction for improved security for small networks and other manufacturers could learn from eero and AVM in working on a secure setup routine along with automatically-updated firmware.
