Cell towers in Sevran (Seine-Saint-Denis)

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

4 underground or tunnel sites and 31 buildings and 7 pylons carry the commune's antennas.

Antennas are listed at Chem du Marais du Souci, Chemin du Marais du Souci, Stade Jean Guimier, Les Beaudottes, 1 Avenue de Lattre de Tassigny and 6/8 Avenue Youri Gargarine.

Over the past 12 months ANFR recorded 44 new systems here. ANFR has approved 3 new sites that are not live yet, plus additions on 6 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at Freinville, Orange (4G and 5G, including 5G at 3.5 GHz) and SFR (4G and 5G, including 5G at 3.5 GHz) at 1 Avenue Salvador Allende. 25 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (31 of 42), so heights stay modest; the tallest support is 58 m at 2 Allee la Boetie.

Systems from 1996 are still on the register. Bouygues Telecom opened 5G here in November 2020; SFR followed in December 2020, Free Mobile followed in December 2020. 2013 was the busiest year, with 60 new systems, most of them 4G.

13 supports carry only Bouygues Telecom.

On 3.5 GHz, the fastest 5G band: Free Mobile on 11 of its 12 masts, Bouygues Telecom on 9 of its 20 masts, Orange on 9 of its 10 masts and SFR on 6 of its 12 masts.

Nearby, Villepinte (2 km to the north) has a camouflaged "tree" pylon among its supports.

At 7 km² with 52,535 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.

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