Cell towers in Annecy (Haute-Savoie)

2 churches or religious buildings and 49 buildings, 23 pylons and 1 radio relay tower carry the commune's antennas.

Antennas are listed at 12 Rue Lionel Terray, ZI de Vovray, Le Peutet, La Combe et les Hesserts, 26 rue des Soeurs Blanches and avenue de la Plaine.

Over the past 12 months ANFR recorded 46 new systems here. ANFR has approved 2 new sites that are not live yet, plus additions on 18 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 250 Route D Argonay and Orange (4G and 5G, including 5G at 3.5 GHz) at Esplanade le Pâquier. 55 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

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

Systems from 1992 are still on the register. Free Mobile opened 5G here in December 2020; SFR followed in May 2021, Orange followed in May 2021. 2013 was the busiest year, with 172 new systems, most of them 4G.

Most antennas sit on rooftops (49 of 76), so heights stay modest; the tallest support is 70 m at Chanteloup.

3 masts carry all four networks; 22 supports carry only Orange.

Among the 33 Haute-Savoie towns with at least five masts, Annecy ranks 1st by mast count. With 76 masts for 132,117 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 25 of its 35 masts, SFR on 25 of its 37 masts, Orange on 24 of its 39 masts and Free Mobile on 19 of its 25 masts.

Viry lies 24 km to the north and has only 7 masts.

The widest declared gap between neighbouring supports is about 4.2 km, to the south-west of the centre.

At 70 km² with 132,117 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA du Grand Annecy intercommunal grouping.

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