Wi-Fi 6E: Europe opens up to the new, faster and more efficient Wi-Fi

The European Commission has published a decision in the Official Journal preparing for the arrival of Wi-Fi 6E: Member States have until December 1 to comply.

Europe is finally embarking on the Wi-Fi 6E shift. In the Official Journal of June 30 of the EU, was published the Commission decision authorizing all Member States to use this wireless communication protocol on new frequencies, located between 5 945 and 6 425 MHz – those- these are commonly referred to as the 6 GHz band – in addition to those already in place.

Today, Wi-Fi uses two portions of the radio spectrum: the so-called 2.4 GHz band (which covers the band going from 2,400 to 2,483.5 MHz) and the 5 GHz band (which goes from 5,150 at 5,350 MHz, as well as from 5,470 to 5,725 MHz). As it stands, Wi-Fi therefore has access to 538.5 MHz of spectrum. However, Wi-Fi 6E gives access to a third portion of the spectrum and, ultimately, has 480 MHz more frequencies.

More throughput, less latency with Wi-Fi 6E

The deployment of Wi-Fi elsewhere in the radio spectrum intends to address several issues: the current bands used by Wi-Fi are subject to sharing constraints with other uses. There is also the issue of flows that must follow, as new uses and needs emerge. In addition, there are also risks of interference to be taken into account.

With 480 MHz of contiguous spectrum, Wi-Fi 6E is therefore not found in the situation of 5 GHz Wi-Fi which must, reminds the National Frequencies Agency, listen to the band before transmitting and change channels when it detects a radar signal. It offers wider communication channels (six 80 MHz channels or three 160 MHz channels), which opens the way to higher speeds, among other things.

Besides faster download speeds, the Wi-Fi 6E will also, according to the Wi-Fi Alliance consortium, ” provide better network performance and support more Wi-Fi users at once, even in very dense and congested environments “. This will require compatible devices certified Wi-Fi 6E. This process has been underway since the start of the year.

Member States are requested to make the frequencies 5 945-6 425MHz available by 1 December 2021 at the latest, ” on a non-exclusive basis, without interference and without protection “. Countries are then free to adapt earlier. There is no need to rush, though: only one in five Wi-Fi devices is expected to be suitable for Wi-Fi 6E in 2022, according to IDC.
