Cell towers in Beauchamp (Val-d'Oise)

1 church or religious building and 3 buildings and 1 pylon carry the commune's antennas.

Masts stand at 35 rue de l'Egalité, avenue de l'Egalité and 35 Av. de l Egalite.

The declared supports are a 26 m building, at 35 rue de l'Egalité, for Orange; a 43 m pylon, at avenue de l'Egalité, for Bouygues Telecom; a 16 m building, at 35 Av. de l Egalite, for Free Mobile; a 12 m building, for SFR.

ANFR lists a 43 m pylon at avenue de l'Egalité as the tallest structure. The median height of measured supports is 26 m.

Systems from 1999 are still on the register. Bouygues Telecom opened 5G here in January 2021; Free Mobile followed in July 2022, Orange followed in August 2022. 2019 was the busiest year, with 16 new systems, most of them 4G.

Approved additions not yet in service are pending on 2 existing masts, for example Orange (5G 2100 MHz) at 35 rue de l'Egalité and SFR (5G 3.5 GHz) at 51 Avenue Pasteur. 4 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Among the 43 Val-d'Oise towns with at least five masts, Beauchamp ranks 41st by mast count. With 5 masts for 9,849 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (6).

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on all 2 masts, Free Mobile on all 2 masts and Orange on all 2 masts.

Taverny lies 1.6 km to the north-east and has 21 masts, more than here.

Only one mast carries all four networks.

Figures above cover installations declared to ANFR as in service or technically operational, as of October 2026; approved projects are not counted.
