Systems from 1997 are still on the register. Local 5G started with Free Mobile in December 2020; SFR followed in November 2021, Bouygues Telecom followed in January 2022. 2021 was the busiest year, with 12 new systems, most of them 4G.

Over the past 12 months ANFR recorded 8 new systems here. 4 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: Free Mobile on all 4 masts, Bouygues Telecom on all 2 masts, SFR on all 2 masts and Orange on its only mast. 5G is on 100% of masts here, against 80% across Haute-Savoie towns with five or more masts.

Most antennas sit on rooftops (6 of 7), so heights stay modest; the tallest support is 53 m at 108 Route de Genève.

4 supports carry only Free Mobile.

Annemasse lies 2.6 km to the north-east and has 11 masts, more than here.

At 4 km² with 11,423 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons.

Most of the town's 7 masts are buildings (6).

Of the 72 systems declared here, 18 are installed but not yet in commercial service (ANFR, as of October 2026).
