Cell towers in Cestas (Gironde)

1 water tower and 21 pylons carry the commune's antennas.

Antennas are listed at Le Puch Ouest, Avenue des Victimes du Devoir, La Moutine, Rivière, St Clair and 2 Chem de la Croix D'Hins.

Over the past 12 months ANFR recorded 9 new systems here. ANFR has approved 2 new sites that are not live yet, plus additions on 4 existing masts. New: Bouygues Telecom (4G and 5G) at 21 Chem de Caussat and Orange (4G and 5G, including 5G at 3.5 GHz) at Marticot. 16 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The highest support stands 50 m at Baron (pylon). The median height of measured supports is 36 m.

Systems from 1994 are still on the register. Bouygues Telecom opened 5G here in November 2020; Free Mobile followed in December 2020, SFR followed in May 2021. 2013 was the busiest year, with 34 new systems, most of them 4G.

On 3.5 GHz, the fastest 5G band: Orange on all 9 masts, Bouygues Telecom on 8 of its 9 masts, Free Mobile on 7 of its 11 masts and SFR on 5 of its 6 masts.

Nearby, Gradignan (6.3 km to the north-east) has only 14 masts.

The widest declared gap between neighbouring supports is about 2.2 km, to the south-east of the centre.

Only one mast carries all four networks.

Among the 62 Gironde towns with at least five masts, Cestas ranks 6th by mast count. With 22 masts for 16,666 residents, or 13 per 10,000, it has more masts per inhabitant than the median for those towns (10).

16,666 residents over 100 km²: supports are mostly pylons, not rooftops. It is part of the CC Jalle-Eau-Bourde intercommunal grouping.

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