Huawei pushes Wi-Fi to 10 GBps

Huawei recently demonstrated up to 10 GBps data rate over a Wi-Fi link on its campus in Shenzen, in China. It expects that this technology could be available in the market by 2018. Huawei is now chairing the IEEE 802.11ax task group working on developing the associated new standard.

This demonstration of leading edge Wi-Fi capability, complements recent Huawei investments (£374m) in developing 5G (cellular) technology - which also has potential to reach 10 Gbps, with commercial deployment possible by 2020 [depending on spectrum availability]. A key difference with the Wi-Fi connectivity is that likely smaller cell size means that few users will share the capacity and it will be easier to deliver a higher quality connection.

Together with investments in R&D on extending DSL technology (Gfast), it looks as though Huawei will be well positioned to offer a full suite of higher performance connecivity products to operators and consumers.

Poor digital connectivity imposes costs on public services

A recent report commissioned by O2 and the Centre for Economic and Business Research (CEBR) highlights the significant costs that poor connectivity imposes on public services. This issue is especially important for front-line staff, who could use mobile devices to make it easier to complete records etc. whilst in the field with their clients. With poor wireless network coverage in a number of the target areas, however, the workers have to follow a more time consuming process - with paper-based forms etc..

TV White Spaces in your new TV receiver ?

With TV white spaces having been given the green light to become a real commercial proposition in the UK this year - with many other countries at different stages of their regulatory journey, the technology may soon start to be incorporated in a range of consumer as well as professional devices.

Our founder, Andrew Stirling, was quoted in a recent article in Videonet by digital broadcasting columnist Barry Flynn, discussing the prospects for TV white spaces coming to a TV set near you. After all the UHF bands which are home to TV white spaces are already well catered for in terrestrial TV receivers and antenna systems.

Wi-Fi hotspots now at 44m and counting

The number of Wi-Fi hotspots continues to grow, worldwide. A recent report published by the largest commercial international Wi-Fi service provider, iPass, provides a current status for the availability of Wi-Fi hotspots in different countries and estimates future growth. Its live map shows how the over 44 million hotspots are distributed across the globe.  Three quarters of these are hosted by domestic access points. Half of the total number are available to iPass subscribers (mostly business people) to enable them to enjoy roaming connections.

The USA, France and the UK (which has with a hot-spot for every 11 people) occupy the three top places in terms of hot-spot density. By 2018, iPass estimates that there will be 340m hot-spots - one for every 20 people on the planet.

With the rapid expansion of demand for capacity, there has been great commercial interest in building networks of Wi-Fi hotspots – facilitated by at least the operating costs being picked up by end users. Internet service providers typically supply Wi-Fi access points as part of the broadband access service and now increasingly see these as an attractive means of supporting a comprehensive Wi-Fi coverage. This coverage can translate into revenues from mobile operators seeking to offload traffic from cellular hotspots as well as end users who explicitly need Wi-Fi access as they move around.

BT operates a service called Openzone – based on around 5m access points deployed in customer premises across the UK. In return for allowing their own access network to be partitioned (into private and public networks), these customers can enjoy BT Wi-Fi access when they are travelling around.

Larkhill recently presented at the World WiFi Summit, in Barcelona on 29th October 2014. Our talk introduced the topic of dynamic sharing of the white spaces spectrum (DSA) and its implications for the future of Wi-Fi - particularly noting the recent publication of the IEEE 802.11 af standard, which adds TV white spaces to the growing family of Wi-Fi bands (currently 2.4 GHz and 5 GHz).
