Cell towers in Pornichet (Loire-Atlantique)

Declared supports include 1 water tower and 1 historic monument, with pylons making up most of the remainder.

Antennas are listed at 130 boulevard des Océanides, Les Océanes, 14 Place Aristide Briand, Hotel Kerjuliette 2 Avenue des Bleuets, La Ville Ès Blais and La Ville Es Blais.

ANFR lists an 89 m pylon at La Ville Es Blais as the tallest structure. The median is 26 m, slightly below the Loire-Atlantique median of 32 m.

Systems from 1996 are still on the register. Local 5G started with Free Mobile in December 2020; Orange followed in December 2021, Bouygues Telecom followed in March 2022. 2022 was the busiest year, with 36 new systems, most of them 4G.

Over the past 12 months ANFR recorded 16 new systems here. Approved additions not yet in service are pending on 3 existing masts, for example Free Mobile (4G and 5G, including 5G at 3.5 GHz) at La Ville Ès Blais, SFR (5G 2100 MHz) at Les Océanes and SFR (4G and 5G) at La Ville Es Blais. 9 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: Bouygues Telecom on 4 of its 5 masts, Free Mobile on 4 of its 6 masts, Orange on 4 of its 5 masts and SFR on 4 of its 5 masts.

3.4 km to the north-west, neighbouring La Baule-Escoublac has 28 masts, more than here.

Only one mast carries all four networks; 3 supports carry only Orange.

Among the 65 Loire-Atlantique towns with at least five masts, Pornichet ranks 12th by mast count. With 11 masts for 12,800 residents, or 9 per 10,000, it has more masts per inhabitant than the median for those towns (8).

12,800 residents over 13 km²: supports are mostly pylons, not rooftops. It is part of the CA de la Région Nazairienne et de l'Estuaire (CARENE) intercommunal grouping.

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