Cell towers in Clichy-sous-Bois

Most of the town's 16 masts are buildings (14); 1 water tower make up the rest of the mix.

Declared locations include Tour Victore Hugo, 8 Allée Romain Rolland, 12 allée de la Fosse Mossoin-Cc Clichy 2, 20 Allée de la Fausse Maussoin, La Lorette and 74/78 rue du Chem des Postes.

20 systems were switched on in the past 12 months. ANFR has approved 2 new sites that are not live yet, plus additions on one existing mast. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 4 Allée des Châtaigniers and SFR (3G, 4G and 5G, including 5G at 3.5 GHz) at 8 Allee du Rouaillier. 12 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2021 was the busiest year, with 27 new systems, most of them 5G. SFR opened 5G here in November 2020; Bouygues Telecom followed in November 2020, Free Mobile followed in December 2020. The oldest transmitter still listed here goes back to 1999.

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

Livry-Gargan lies 1.3 km to the north-west and has 28 masts, more than here.

14 of the 16 masts are rooftop-mounted. The tallest support is 59 m (building). The median is 21 m, slightly below the Seine-Saint-Denis median of 25 m.

Of the 16 masts in the commune, only one mast carries all four networks, and Free Mobile is the only carrier on 4 masts.

Most declared azimuths point outward, along a corridor or valley rather than at the centre.

By mast count, Clichy-sous-Bois is 29th of the 36 Seine-Saint-Denis towns that have five or more. With 16 masts for 29,354 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (7).

At 4 km² with 29,354 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.
