Systems from 2004 are still on the register. Local 5G started with Free Mobile in December 2020; Bouygues Telecom followed in April 2021, Orange followed in October 2021. 2021 was the busiest year, with 18 new systems, most of them 5G.

Approved additions not yet in service are pending on one existing mast, for example Bouygues Telecom (4G 700 MHz) at Le Murier. 8 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Only one mast carries all four networks; 3 supports carry only Orange.

4 masts belong to Totem and 1 to ATC France.

The widest declared gap between neighbouring supports is about 1.6 km, to the north-west of the centre. Most declared azimuths point outward, along a corridor or valley rather than at the centre.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on all 4 masts, Orange on 3 of its 4 masts, SFR on all 2 masts and Free Mobile on 1 of its 2 masts.

Saint-Martin-d'Heres lies 2.1 km to the west and has 24 masts, more than here.

7,376 residents over 7 km²: supports are mostly pylons, not rooftops.

5 pylons and 2 masts and 1 building carry the commune's antennas.

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