Cell towers in Thiers (Puy-de-Dôme)

Antennas are listed at 5 rue Edouard Michelin, Membrun, Les Belins - les Fayes, Les Berauds, ZA de Felet and Les Champs.

Systems from 2004 are still on the register. Free Mobile opened 5G here in December 2020; SFR followed in August 2021, Bouygues Telecom followed in September 2021. 2016 was the busiest year, with 39 new systems, most of them 4G.

Over the past 12 months ANFR recorded 16 new systems here. Approved additions not yet in service are pending on 3 existing masts, for example Free Mobile (5G 3.5 GHz) at Les Belins - les Fayes, Free Mobile (5G 700 MHz) at 5000 Impasse des Roseaux and Free Mobile (5G 700 MHz) at Les Champs. 11 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists a 39 m pylon at 5000 Impasse des Roseaux as the tallest structure. The median height of measured supports is 25 m.

2 masts carry all four networks; 4 supports carry only Orange.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 5 of its 7 masts, SFR on 5 of its 7 masts, Orange on 4 of its 7 masts and Free Mobile on 3 of its 6 masts.

Nearby, Celles-sur-Durolle (6.8 km to the east) has only 5 masts.

The widest declared gap between neighbouring supports is about 2.3 km, to the north-east of the centre.

Among the 25 Puy-de-Dôme towns with at least five masts, Thiers ranks 6th by mast count. With 14 masts for 11,637 residents, or 12 per 10,000, it has fewer masts per inhabitant than the median for those towns (14).

11,637 residents over 45 km²: supports are mostly pylons, not rooftops. It is part of the CC Thiers Dore et Montagne intercommunal grouping.

Supports split between 13 pylons and 1 building.
