Brazil considers 5G restrictions over altimeter concerns

The Brazilian telecommunications regulator Anatel has proposed curbs on 5G base stations operating near airports.

Brazil’s regulator Anatel is consulting on the creation of buffer zones around airports to protect aeroplane altimeters which operate in a band close to the recently auctioned 5G licences.

Anatel is proposing a 910m radius around airports as well as a 2.1km zone from the end of each aeroplane runway. Within this zone, base station antennas must not point above the horizon line.

This follows a similar decision made by the US regulator, the FCC in late 2021. However, the airport buffers in the US are only temporary.
