Cell towers in Mios (Gironde)

Antennas are listed at La Gare du Nord, Caudos, 1 Route des Douils, Le Barrail, Hobre and Masquet.

The highest support stands 51 m at Les Pelouneyres (pylon). The median is 42 m, above the Gironde median of 36 m.

Systems from 1994 are still on the register. Free Mobile switched on the first 5G here in December 2020; SFR followed in September 2021, Bouygues Telecom followed in October 2021. 2016 was the busiest year, with 43 new systems, most of them 4G.

Over the past 12 months ANFR recorded 19 new systems here. Approved additions not yet in service are pending on 7 existing masts, for example Bouygues Telecom (4G 2100 MHz) at Les Pelouneyres, Bouygues Telecom (4G and 5G) at Caudos and Bouygues Telecom (4G and 5G) at Aire des Gargails. 7 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: Orange on 6 of its 8 masts, Bouygues Telecom on 3 of its 11 masts, Free Mobile on 3 of its 8 masts and SFR on 3 of its 11 masts. 5G is on 65% of masts here, against 89% across Gironde towns with five or more masts.

4 masts carry all four networks.

The widest declared gap between neighbouring supports is about 5.9 km, to the south-west of the centre.

Nearby, Salles (8 km to the south-east) has only 12 masts.

Among the 62 Gironde towns with at least five masts, Mios ranks 12th by mast count. With 17 masts for 12,043 residents, or 14 per 10,000, it has more masts per inhabitant than the median for those towns (10).

12,043 residents over 137 km²: supports are mostly pylons, not rooftops. It is part of the CA du Bassin d'Arcachon Nord (COBAN) intercommunal grouping.

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