Declared supports include 6 underground or tunnel sites, 1 road gantry and 1 camouflaged "tree" pylon, with buildings making up most of the remainder.

68 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on 18 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 44 Rue Jean Jaurès. 32 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

53 of the 69 masts are rooftop-mounted. The tallest support is 60 m at 40 Avenue Boileau (building). The median is 20 m, slightly below the Val-de-Marne median of 25 m.

2020 was the busiest year, with 92 new systems, most of them 5G. Bouygues Telecom switched on the first 5G here in November 2020; Orange followed in December 2020, Free Mobile followed in December 2020. The oldest transmitter still listed here goes back to 1995.

By mast count, Champigny-sur-Marne is 1st of the 44 Val-de-Marne towns that have five or more. With 69 masts for 78,072 residents, or 9 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 18 of its 21 masts, Orange on 16 of its 22 masts, SFR on 13 of its 21 masts and Bouygues Telecom on 12 of its 25 masts.

Nearby, Joinville-le-Pont (1.7 km to the north-west) has only 10 masts.

At 11 km² with 78,072 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.
