Cell towers in Les Sables-d'Olonne (Vendée)

1 church or religious building and 22 pylons, 3 buildings and 1 silo carry the commune's antennas.

Masts stand at Le Moulin des Roses, 2 quai D'Allégement, rue de la Belle Olonnaise, Touvent, Avenue Rhin et Danube and Les Grandes Garnaudières.

Over the past 12 months ANFR recorded 65 new systems here. ANFR has approved 2 new sites that are not live yet, plus additions on 7 existing masts. New: Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at 4 Rue Jacques Monod, Free Mobile (4G and 5G) at 17 Promenade de Cayola and SFR (3G, 4G and 5G, including 5G at 3.5 GHz) at 4 Rue Jacques Monod. 25 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists an 85 m pylon at 12 rue Jacquard as the tallest structure. The median is 29 m, slightly below the Vendée median of 32 m.

2 masts belong to the commune itself and 7 to Totem; the rest sit mainly on private buildings.

Systems from 1995 are still on the register. Free Mobile switched on the first 5G here in December 2020; Orange followed in July 2021, SFR followed in October 2021. 2021 was the busiest year, with 83 new systems, most of them 5G.

4 masts carry all four networks; 7 supports carry only Free Mobile.

Among the 29 Vendée towns with at least five masts, Les Sables-d'Olonne ranks 2nd by mast count. With 27 masts for 49,603 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (11).

On 3.5 GHz, the fastest 5G band: Free Mobile on 14 of its 15 masts, Bouygues Telecom on all 13 masts, Orange on all 12 masts and SFR on all 12 masts.

16 km to the north, neighbouring Bretignolles-sur-Mer has only 7 masts.

The widest declared gap between neighbouring supports is about 3 km, to the east of the centre.

49,603 residents over 86 km²: supports are mostly pylons, not rooftops. It is part of the CA Les Sables d'Olonne Agglomération intercommunal grouping.

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