Cell towers in Roquebrune-Cap-Martin

2 supports are declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

2 underground or tunnel sites and 6 buildings, 4 pylons and 2 camouflaged "tree" pylons carry the commune's antennas.

Antennas are listed at Ech de Roquebrune-Cap-Martin, 222 avenue du Semaphore, St Pancrace, Résidence le Ramengo, 65 Rue de Profondville and Chem des Vallières.

ANFR has approved one new site that is not live yet, plus additions on 3 existing masts. New: Bouygues Telecom (4G and 5G) at 110 Montée du Stade. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Systems from 1994 are still on the register. Local 5G started with Free Mobile in December 2020; Orange followed in March 2022, Bouygues Telecom followed in April 2023. 2018 was the busiest year, with 33 new systems, most of them 4G.

The tallest structure is a 41 m lighthouse or signal station at 222 avenue du Semaphore. The median height of measured supports is 19 m.

Only one mast carries all four networks; 5 supports carry only Orange.

On 3.5 GHz, the fastest 5G band: Free Mobile on all 6 masts, Orange on 4 of its 8 masts, Bouygues Telecom on 3 of its 7 masts and SFR on 3 of its 7 masts.

Nearby, Beausoleil (5.3 km to the south-west) has only 8 masts.

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