Cell towers in Annemasse (Haute-Savoie)

Declared locations include 26 rue de l'Ile de France, 21 Avenue de Verdun, 77 Route de Thonon, 5 Rue Vernand, Malbrande and Rue du Chablais Prolongee.

8 systems were switched on in the past 12 months. ANFR has approved 2 new sites that are not live yet, plus additions on 3 existing masts. New: Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at 4 Rue des Lilas, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 2 Rue Henry Bordeaux and SFR (3G, 4G and 5G, including 5G at 3.5 GHz) at 4 Rue des Lilas. 8 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2021 was the busiest year, with 24 new systems, most of them 4G. Local 5G started with Free Mobile in December 2020; Orange followed in May 2021, SFR followed in March 2023. The oldest transmitter still listed here goes back to 1992.

10 of the 11 masts are rooftop-mounted. The tallest support is 34 m at 26 rue de l'Ile de France (building). The median height of measured supports is 26 m.

Of the 11 masts in the commune, only one mast carries all four networks, and Free Mobile is the only carrier on 4 masts.

By mast count, Annemasse is 6th of the 33 Haute-Savoie towns that have five or more. With 11 masts for 37,628 residents, or 3 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

3.5 GHz 5G is declared by Free Mobile on all 6 masts, Orange on all 5 masts, Bouygues Telecom on all 4 masts and SFR on 4 of its 5 masts.

Nearby, Gaillard (2.6 km to the south-west) has only 7 masts.

At 5 km² with 37,628 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Annemasse-Les Voirons-Agglomération intercommunal grouping.

10 buildings and 1 pylon carry the commune's antennas.
