2021 was the busiest year, with 20 new systems, most of them 5G. Bouygues Telecom opened 5G here in November 2020; Free Mobile followed in September 2021, SFR followed in November 2021. The oldest transmitter still listed here goes back to 1995.

9 systems were switched on in the past 12 months. Approved additions not yet in service are pending on 2 existing masts, for example Free Mobile (5G 700 MHz) at Avenue Paul Vaillant Couturier and Free Mobile (5G 700 MHz) at 53 Rue Charles Frerot. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

12 of the 16 masts are rooftop-mounted. The tallest support is 49 m at 2 rue de Thiberville (building). The median height of measured supports is 23 m.

Of the 16 masts in the commune, Bouygues Telecom is the only carrier on 6 masts.

3.5 GHz 5G is declared by Free Mobile on all 6 masts, Bouygues Telecom on 3 of its 7 masts, Orange on 3 of its 4 masts and SFR on 1 of its 2 masts.

Le Kremlin-Bicetre lies 1.4 km to the east and has 31 masts, more than here.

At 1 km² with 19,963 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.
