Cell towers in Biscarrosse (Landes)

2 water towers and 15 pylons, 1 mast and 1 camouflaged "tree" pylon carry the commune's antennas.

Masts stand at La Rive, Rue du Capitaine Nemo, Des Hautes Rives, Ch D'en Hill, avenue de Laoudie - D.146 and Déchetterie.

The tallest structure is a 67 m water tower at Sencion. The median is 30 m, slightly below the Landes median of 37 m.

Systems from 1997 are still on the register. Free Mobile opened 5G here in January 2021; SFR followed in December 2021, Bouygues Telecom followed in January 2022. 2022 was the busiest year, with 45 new systems, most of them 5G.

Over the past 12 months ANFR recorded 45 new systems here. Approved additions not yet in service are pending on 6 existing masts, for example Bouygues Telecom (4G and 5G) at avenue du Pyla, Bouygues Telecom (4G) at La Rive and Bouygues Telecom (5G 3.5 GHz) at 1 Boulevard D'Arcachon. 13 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3 masts carry all four networks; 6 supports carry only Orange.

Among the 28 Landes towns with at least five masts, Biscarrosse ranks 1st by mast count.

On 3.5 GHz, the fastest 5G band: Orange on all 12 masts, Free Mobile on 7 of its 9 masts, SFR on 7 of its 10 masts and Bouygues Telecom on 6 of its 10 masts.

8.9 km to the south-east, neighbouring Parentis-en-Born has only 6 masts.

The widest declared gap between neighbouring supports is about 4.6 km, to the north-east of the centre.

15,836 residents over 194 km²: supports are mostly pylons, not rooftops. It is part of the CC des Grands Lacs intercommunal grouping.

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