The government wants to “green” the next step of 5G

The government has sent a request to the telecoms regulator to include the environmental issue in the specifications aimed at allocating future 5G frequencies.

This is another part of the government roadmap aiming to reconcile digital and environment. While the deployment of the first 5G networks began in France at the end of 2020, the executive wants the next major phase of the deployment of mobile ultra-broadband to take more account of environmental issues. And for this, he appeals to the telecoms regulator.

A framework letter was sent to the Electronic Communications Regulatory Authority, the government said on February 23. This one asks him, without much more precision, to ” take into account environmental issues in the allocation criteria for 5G 26 GHz band frequencies “, And to examine” all ways and means In the matter.

Concretely, this will have the effect of adding requirements to the specifications that mobile telephone operators will have to comply with in order to obtain licenses for 26 GHz frequencies. However, this subject is not for tomorrow: the allocation of this band will only occur in a few years – the regulator has no very precise timetable for the time being.

If the roadmap intends to establish new constraints on 5G “to green it”, it should be noted that the government also sees this generation of mobile telephony as a means of using it as a lever for the ecological transition, by supporting the development of innovative solutions. The government sees it too an asset for agricultural issues, which are linked to environmental issues.

5G frequencies that won’t happen right away

Work on the 26 GHz band is still at a very early stage: there is no commercial deployment in progress, due to a lack of allocation to operators, and the timetable has not been fixed. Two steps have nevertheless been taken: a public consultation in 2018 on what to do with the 26 GHz band, and experiments from 2019 to explore potential uses.

The 26 GHz band, which actually spans 24.25 – 27.5 GHz in the spectrum, belongs to the millimeter wave category. As you can guess, this means that their wavelength is very narrow: the distance between two peaks measures from one centimeter to one millimeter. This has the effect of increasing the frequency compared to more “stretched” waves and, therefore, increasing the throughput.

It will make it possible to deliver very high speeds, much higher than in 4G or even than certain other bands used by 5G. She ” will be the key to very high speed ‘wireless fiber’ “Said the National Frequency Agency about him. But if it has not been prioritized for the launch of 5G, it is because it has very poor range and struggles to enter buildings.

It is first in small areas, but heavily frequented, that the 26 GHz band should give its full potential: a shopping center, a football stadium or the Paris ring road. Tourist areas could also benefit. With the summer Olympics being held in Paris in 2024, the 26 GHz band could again be very useful to absorb all connections and deliver high speeds.

Sure: you are paying too much for your 4G plan
