5G: possible interference with another service

Launched at the end of 2020 in France, 5G operates in several frequency bands, including the 3.4-3.8 GHz band. Arcep is concerned about possible interference with fixed satellite earth stations, as these use the 3.8-4.2 GHz band.


Such proximity could cause interference. This is why the telecom regulator decided to launch a public consultation on 27 July: "The purpose of this public consultation is to clarify the conditions of coexistence, both from the point of view of the technical conditions to be respected and their location and duration. The proposed text seeks to distinguish between existing stations and those that could be deployed in the future, and to take into account the levels of constraints on the deployment of 5G networks, which may vary according to the stations and their location". Contributions from the stakeholders are expected before 29 October 2021.


Arcep also recalls that measures have already been taken in this regard: "In order to avoid such interference, Arcep's decisions of 12 November 2020 authorising mobile operators to use the 3.4-3.8 GHz band specify the obligation for mobile operators to take the necessary measures to comply with emission power levels".
