Cell towers in Passy (Haute-Savoie)

1 camouflaged "tree" pylon and 8 pylons and 1 building carry the commune's antennas.

Masts stand at Praz Coutant, Le Plan de la Gouille, 250 Impasse des Garages, 330 Rue du Stade, Le Coudray Est and Les Chavannes.

2 masts belong to the commune itself and 2 to On Tower France; the rest sit mainly on private buildings.

Systems from 2001 are still on the register. Local 5G started with Free Mobile in December 2020; SFR followed in August 2021, Bouygues Telecom followed in August 2021. 2022 was the busiest year, with 23 new systems, most of them 4G.

Over the past 12 months ANFR recorded 15 new systems here. Approved additions not yet in service are pending on 3 existing masts, for example Bouygues Telecom (2G, 3G, 4G and 5G) at 1901 Chem de Bay, Free Mobile (4G 800 MHz) at Le Plan de la Gouille and Free Mobile (4G 800 MHz) at Praz Coutant. 5 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The tallest structure is a 36 m pylon at 250 Impasse des Garages. The median height of measured supports is 28 m.

2 masts carry all four networks.

On 3.5 GHz, the fastest 5G band: SFR on 4 of its 7 masts, Bouygues Telecom on 3 of its 6 masts, Free Mobile on 3 of its 6 masts and Orange on 2 of its 4 masts.

The widest declared gap between neighbouring supports is about 2.3 km, to the west of the centre.

Saint-Gervais-les-Bains lies 3.9 km to the south-east and has 10 masts declared.

Among the 33 Haute-Savoie towns with at least five masts, Passy ranks 8th by mast count. With 10 masts for 10,856 residents, or 9 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

10,856 residents over 80 km²: supports are mostly pylons, not rooftops. It is part of the CC Pays du Mont-Blanc intercommunal grouping.

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