Systems from 1997 are still on the register. Bouygues Telecom opened 5G here in November 2020; Free Mobile followed in December 2020, SFR followed in August 2021. 2014 was the busiest year, with 45 new systems, most of them 4G.

Over the past 12 months ANFR recorded 16 new systems here. Approved additions not yet in service are pending on 5 existing masts, for example Bouygues Telecom (4G 2600 MHz) at 64 RTE Nationale 6, Free Mobile (5G 700 MHz) at Résidence Saint Médard and Orange (4G 700 MHz). 12 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (12 of 15), so heights stay modest; the tallest support is 31 m at 8 rue Jean Xxiii.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 5 of its 7 masts, Orange on 5 of its 6 masts, SFR on 5 of its 8 masts and Free Mobile on 4 of its 6 masts.

Nearby, Epinay-sous-Senart (1.5 km to the east) has only 6 masts.

Colocation covers 9 supports.

At 7 km² with 25,643 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Val d'Yerres Val de Seine intercommunal grouping.

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