Cell towers in Carcans (Gironde)

Declared supports include 3 camouflaged "tree" pylons and 1 water tower, with pylons making up most of the remainder.

Antennas are listed at La Baynasse, Les Bombannes, RTE de l'Océan, Troussas, Le Poutch and 4 Rue des Acacias.

The tallest structure is a 50 m pylon at RTE de l'Océan. The median height of measured supports is 36 m.

Systems from 1998 are still on the register. Free Mobile opened 5G here in November 2021; SFR followed in February 2022, Bouygues Telecom followed in September 2023. 2018 was the busiest year, with 30 new systems, most of them 4G.

Over the past 12 months ANFR recorded 13 new systems here. Approved additions not yet in service are pending on one existing mast, for example Free Mobile (5G 700 MHz) at La Baynasse. 9 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Among the 62 Gironde towns with at least five masts, Carcans ranks 31st by mast count. With 9 masts for 2,415 residents, or 37 per 10,000, it has more masts per inhabitant than the median for those towns (10).

On 3.5 GHz, the fastest 5G band: Free Mobile on 5 of its 6 masts, Bouygues Telecom on 3 of its 6 masts, SFR on 3 of its 6 masts and Orange on 2 of its 3 masts.

The widest declared gap between neighbouring supports is about 2.9 km, to the east of the centre.

Hourtin lies 12 km to the north and has less 5G (78%).

Only one mast carries all four networks.

2,415 residents over 201 km²: supports are mostly pylons, not rooftops.

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