Cell towers in Clamart (Hauts-de-Seine)

Declared supports include 1 church or religious building, with buildings making up most of the remainder.

Masts stand at 22 rue Paul Vaillant-Couturier, 107-115 Rue de la Porte de Trivaux, 107/117 rue de la Porte de Trivaux, 13 Avenue du Général Eisenhower, 463 Avenue du Général de Gaulle and 169 rue de la Porte de Trivaux.

2 masts belong to the commune itself; the rest sit mainly on private buildings.

Systems from 1995 are still on the register. Bouygues Telecom opened 5G here in November 2020; Orange followed in December 2020, Free Mobile followed in December 2020. 2013 was the busiest year, with 53 new systems, most of them 4G.

Over the past 12 months ANFR recorded 11 new systems here. Approved additions not yet in service are pending on 3 existing masts, for example Bouygues Telecom (5G 3.5 GHz) at 85 avenue Henri Barbusse, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 85 avenue Henri Barbusse and SFR (5G 2100 MHz) at 107/117 rue de la Porte de Trivaux. 20 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (23 of 24), so heights stay modest; the tallest support is 39 m.

On 3.5 GHz, the fastest 5G band: Free Mobile on all 11 masts, Bouygues Telecom on 8 of its 13 masts, Orange on 8 of its 9 masts and SFR on 8 of its 9 masts.

Le Plessis-Robinson lies 1.6 km to the south and has only 18 masts.

Only one mast carries all four networks.

At 9 km² with 58,576 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Métropole du Grand Paris intercommunal grouping.

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