3 questions about the future of Wi-Fi and its promise of colossal speeds

There is a change for Wi-Fi. The next major evolution of the famous wireless communication technology is coming. Called Wi-Fi 7, it will further increase speeds and further decrease latency.

A small revolution should soon shake the telecoms world. Indeed, a new stage in the development of Wi-Fi is about to be reached within a few months, with the arrival of a whole new generation of wireless network. It is Wi-Fi 7. Behind this name, which will end up responding in the press and on product labels, hides the future IEEE 802.11be standard.

What is Wi-Fi 7?

The IEEE 802.11be standard, currently under development, is part of the successive progress that has been made in telecommunications. They range from Wi-Fi 1 (released in 1999) to 6 (certified in 2019), passing through four intermediate generations. In the past, they were designated by undrinkable codes (802.11b, 802.11n, 802.11ac, etc.). Since 2018, a new naming convention has been respected.

A new generation of Wi-Fi is coming.

Wi-Fi 7 will use the three segments of the spectrum allocated to Wi-Fi, namely the 2.4 GHz bands (which in fact extends from 2400 to 2483.5 MHz), 5 GHz (from 5 150 to 5 MHz). 350 MHz, as well as 5,470-5,725 MHz) and 6 GHz (5,945-6,425 MHz), with support to work with existing devices. The use of the 6 GHz band in Wi-Fi is recent: it is permitted with the Wi-Fi 6E standard.

What strengths for Wi-Fi 7?

The Wi-Fi Alliance, a body that brings together manufacturers of wireless systems, in fact a brief description on his site. It is suggested speeds that can exceed 30 Gbit / s ” to increase performance, enable Wi-Fi innovations and expand use cases With improvements in the physical layer and in the link layer, at the level of the access controls to the media (MAC).

« Other Wi-Fi 7 enhancements will support reduced latency and jitter for delay-sensitive applications including virtual reality and augmented reality, 4K and 8K video streaming, automotive, cloud computing , games and video applications, as well as critical and industrial applications Like the Wi-Fi Alliance.

Overall, the stated objective of Wi-Fi 7 is to provide speeds up to 2.4 times those delivered by the two most advanced generations, namely Wi-Fi 6 and 6E. And the latter already offer considerable speeds – Wi-Fi 6, depending on the circumstances, can go up to 10.5 Gbps. Finally, Wi-Fi 7 will also bring improvements to limit interference between side-by-side wireless networks.

When will Wi-Fi 7 arrive?

We must not get carried away: the certification of Wi-Fi 6E took place in 2021 and the very first compatible routers were not released until 2021. This new generation is still very little distributed among the general public. The same long road awaits Wi-Fi 7, with three key moments: the certification date, the arrival of the first adapted devices and, finally, the appropriation by individuals.

Under these conditions, demonstrations could take place from the CES show in 2022, with technologies still not finalized and certified. The certification itself is mentioned for 2022 or 2023, at a date not yet determined. Then the products will be released in 2023 or 2024. As for distribution to the public, we will have to wait, because a new Wi-Fi is not always enough to trigger a purchase.

The manufacturers of the communicating chips are in any case in battle order. At the beginning of June, the specialized magazine DigiTimes reported that several large founders such as Broadcom, Qualcomm and MediaTek are in place and have started to prepare the development of components tailored for the IEEE 802.11be standard. And that, assuming the certification doesn’t experience any bumps in the road.
