Cell towers in Corbeil-Essonnes (Essonne)

Most of the town's 36 masts are buildings (28); 1 water tower and 1 camouflaged "tree" pylon make up the rest of the mix.

Antennas are listed at Les Caillettes, 4 avenue du 8 Mai 1945 (rn 446), quai Mauzaisse, 1 Boulevard Henri Dunant - N191, Rue Jacques Anquetil and 12 rue Fernand Laguide.

ANFR has approved one new site that is not live yet, plus additions on 4 existing masts. New: Bouygues Telecom (4G and 5G) at 73 avenue Serge Dassault. 24 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3 masts belong to the commune itself and 2 to On Tower France; the rest sit mainly on private buildings.

Systems from 1996 are still on the register. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in December 2020, SFR followed in January 2021. 2021 was the busiest year, with 50 new systems, most of them 5G.

Most antennas sit on rooftops (28 of 36), so heights stay modest; the tallest support is 47 m at 31 avenue Leon Blum.

13 supports carry only Free Mobile.

On 3.5 GHz, the fastest 5G band: Free Mobile on 14 of its 15 masts, Bouygues Telecom on 11 of its 13 masts, Orange on 7 of its 8 masts and SFR on 5 of its 7 masts.

Nearby, Saint-Pierre-du-Perray (712 m to the north-east) has only 6 masts.

Among the 60 Essonne towns with at least five masts, Corbeil-Essonnes ranks 4th by mast count.

At 11 km² with 54,471 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Grand Paris Sud Seine Essonne Sénart intercommunal grouping.

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