Cell towers in Le Plessis-Robinson

Masts stand at La Boursidière, Terrasse du Plessis - Parc Henri Sellier, 15 avenue Paul Langevin, 46-48 Rue Fernand Fourcade, 42 Rue Arthur Ranc and 5 Place de la Résistance.

Over the past 12 months ANFR recorded 15 new systems here. ANFR has approved 2 new sites that are not live yet, plus additions on 6 existing masts. New: Bouygues Telecom (4G and 5G) and Orange (4G and 5G, including 5G at 3.5 GHz) at 16 Avenue Galilée. 8 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (15 of 18), so heights stay modest; the tallest support is 42 m at Terrasse du Plessis - Parc Henri Sellier.

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 December 2020. 2013 was the busiest year, with 34 new systems, most of them 4G.

On 3.5 GHz, the fastest 5G band: Free Mobile on 5 of its 7 masts, SFR on 5 of its 6 masts, Bouygues Telecom on 4 of its 5 masts and Orange on 4 of its 5 masts. 5G is on 94% of masts here, against 82% across Hauts-de-Seine towns with five or more masts.

Nearby, Clamart (1.6 km to the north) has 24 masts, more than here.

At 3 km² with 28,848 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.

Supports split between 15 buildings and 3 pylons.

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