Cell towers in Noisy-le-Sec (Seine-Saint-Denis)

Most of the town's 26 masts are buildings (23); 1 road gantry make up the rest of the mix.

Declared locations include 14 rue Paul Verlaine, 1 Allée Mansart, 1 Rue Paul Vaillant Couturier, 5 rue Paul Vaillant Couturier, 9 Place du Moulin Fondu and 3 Allee de la Madeleine.

33 systems were switched on in the past 12 months. ANFR has approved 4 new sites that are not live yet, plus additions on 4 existing masts. New: Bouygues Telecom (4G and 5G) at avenue de Rosny, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 23 Boulevard de la République and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 30 Chemin des Carrouges. 15 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

23 of the 26 masts are rooftop-mounted. The tallest support is 58 m at 12 Rue Paul Verlaine (building). The median is 35 m, above the Seine-Saint-Denis median of 25 m.

2020 was the busiest year, with 41 new systems, most of them 5G. Bouygues Telecom opened 5G here in November 2020; Free Mobile followed in December 2020, SFR followed in December 2020. The oldest transmitter still listed here goes back to 1996.

3.5 GHz 5G is declared by Free Mobile on 9 of its 11 masts, Bouygues Telecom on 7 of its 8 masts, Orange on 6 of its 7 masts and SFR on 6 of its 10 masts.

Nearby, Bondy (2.1 km to the north-east) has 34 masts, more than here.

Of the 26 masts in the commune, only one mast carries all four networks.

At 5 km² with 45,510 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.
