Cell towers in Le Rheu (Ille-et-Vilaine)

Systems from 1995 are still on the register. Local 5G started with Free Mobile in December 2020; Bouygues Telecom followed in October 2021, SFR followed in July 2022. 2019 was the busiest year, with 13 new systems, most of them 4G.

Approved additions not yet in service are pending on 2 existing masts, for example Bouygues Telecom (3G 900 MHz) at Lessart and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at ZA du Chêne Vert. 4 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on all 2 masts, Orange on all 2 masts, SFR on all 2 masts and Free Mobile on its only mast. 5G is on 100% of masts here, against 82% across Ille-et-Vilaine towns with five or more masts.

Among the 36 Ille-et-Vilaine towns with at least five masts, Le Rheu ranks 30th by mast count. With 5 masts for 9,839 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

2 masts belong to Cellnex and 1 to Totem.

The widest declared gap between neighbouring supports is about 2 km, to the south-west of the centre.

Pace lies 5.4 km to the north and has 10 masts, more than here.

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