6 supports are declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

Declared supports include 6 underground or tunnel sites and 1 church or religious building, with buildings making up most of the remainder.

8 systems were switched on in the past 12 months. ANFR has approved 3 new sites that are not live yet, plus additions on 6 existing masts. New: Bouygues Telecom (4G and 5G) at 27 avenue du Gal-Leclerc, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 55 Rue Michelet / 115 Rue de la Concorde and Free Mobile (4G and 5G) at 16 Rue Parmentier. 15 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2014 was the busiest year, with 37 new systems, most of them 4G. Local 5G started with Bouygues Telecom in November 2020; Orange followed in December 2020, Free Mobile followed in December 2020. The oldest transmitter still listed here goes back to 1994.

22 of the 30 masts are rooftop-mounted. The tallest support is 55 m at 50 rue Carnot (building). The median height of measured supports is 25 m.

3.5 GHz 5G is declared by Orange on 7 of its 10 masts, Bouygues Telecom on 6 of its 11 masts, Free Mobile on 6 of its 12 masts and SFR on 5 of its 9 masts.

Nearby, Saint-Maurice (1.4 km to the north-west) has only 12 masts.

Of the 30 masts in the commune, Free Mobile is the only carrier on 8 masts.

By mast count, Maisons-Alfort is 10th of the 44 Val-de-Marne towns that have five or more. With 30 masts for 56,799 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (7).

At 5 km² with 56,799 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.
