Cell towers in Chaville (Hauts-de-Seine)

2 supports are declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

Declared supports include 2 underground or tunnel sites, with buildings making up most of the remainder.

Antennas are listed at 1 rue de la Fontaine Henri Iv/Bas Chaville, 7 rue de l'Etang St Denis, 4 rue des Blanchisseurs, 2012 Avenue Roger Salengro, 144 Avenue Roger Salengro and Route du Cordon du Haut.

ANFR has approved 2 new sites that are not live yet, plus additions on 2 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 4 Rue Anatole France and Orange (4G) at Route des Huit Bouteilles. 8 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

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. Bouygues Telecom opened 5G here in November 2020; SFR followed in December 2020, Free Mobile followed in December 2020. 2018 was the busiest year, with 25 new systems, most of them 4G.

Most antennas sit on rooftops (11 of 16), so heights stay modest; the tallest support is 59 m at 1 rue du Gros Chêne.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 4 of its 7 masts, Free Mobile on 3 of its 5 masts, SFR on 3 of its 5 masts and Orange on 2 of its 3 masts.

2 km to the north, neighbouring Ville-d'Avray has only 7 masts.

4 supports carry only Bouygues Telecom.

At 4 km² with 20,594 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.
