8 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on 3 existing masts. New: SFR (4G and 5G, including 5G at 3.5 GHz) at 70 Rue des Plantes. 20 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2014 was the busiest year, with 44 new systems, most of them 4G. Bouygues Telecom switched on the first 5G here in November 2020; Free Mobile followed in December 2020, SFR followed in December 2020. The oldest transmitter still listed here goes back to 1996.

Of the 36 masts in the commune, Bouygues Telecom is the only carrier on 11 masts.

By mast count, Athis-Mons is 3rd of the 60 Essonne towns that have five or more. With 36 masts for 36,613 residents, or 10 per 10,000, it has more masts per inhabitant than the median for those towns (7).

3.5 GHz 5G is declared by Free Mobile on 8 of its 10 masts, Orange on 8 of its 9 masts, SFR on 8 of its 9 masts and Bouygues Telecom on 6 of its 14 masts.

Vigneux-sur-Seine lies 1.6 km to the east and has only 15 masts.

24 of the 36 masts are rooftop-mounted. The tallest support is 44 m (building). The median is 22 m, slightly below the Essonne median of 26 m.

At 9 km² with 36,613 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Métropole du Grand Paris intercommunal grouping.

24 buildings and 12 pylons carry the commune's antennas.
