Cell towers in Roissy-en-Brie (Seine-et-Marne)

Declared supports include 1 water tower, with buildings making up most of the remainder.

Masts stand at 14 Avenue Auguste Renoir, 13 rue Jacques Chaban Delmas, Les 50 Arpents, La Cul de Sac, Les Essarts and 8 Rue de l Egalite.

Most antennas sit on rooftops (8 of 13), so heights stay modest; the tallest support is 53 m at 5 avenue du Général Leclerc.

2 masts belong to the commune itself and 1 to Totem; 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, Orange followed in July 2021. 2021 was the busiest year, with 25 new systems, most of them 5G.

Over the past 12 months ANFR recorded 13 new systems here. Approved additions not yet in service are pending on one existing mast, for example SFR (4G and 5G) at 5 avenue du Général Leclerc. 13 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

4 supports carry only Bouygues Telecom.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 6 of its 7 masts, SFR on all 5 masts, Free Mobile on all 4 masts and Orange on 3 of its 4 masts.

Emerainville lies 3 km to the north-west and has only 8 masts.

Among the 52 Seine-et-Marne towns with at least five masts, Roissy-en-Brie ranks 13th by mast count.

At 14 km² with 23,229 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Paris - Vallée de la Marne intercommunal grouping.

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