ANFR has approved one new site that is not live yet, plus additions on one existing mast. New: Free Mobile (4G and 5G) at Le Murget des Marguerites. 1 Bouygues Telecom 5G transmitter is listed as technically operational — installed, but not yet declared commercially in service.

On 3.5 GHz, the fastest 5G band: Free Mobile on 2 of its 3 masts and Orange on 2 of its 3 masts. No 3.5 GHz from Bouygues Telecom here, only 2100 MHz.

Systems from 1997 are still on the register. Local 5G started with Bouygues Telecom in June 2018; Free Mobile followed in June 2021, Orange followed in November 2024. 2018 was the busiest year, with 19 new systems, most of them 4G.

2 masts belong to On Tower France.

Mantes-la-Ville lies 4.1 km to the north-west and has 21 masts, more than here.

Only one mast carries all four networks.
