Cell towers in Sarcelles (Val-d'Oise)

1 camouflaged "tree" pylon and 21 buildings and 9 pylons carry the commune's antennas.

Antennas are listed at 29-31 rue de l'Escouvrier, 200 Avenue de la Division Leclerc, 15 Rue de l'Escouvrier, Les Vignes Blanches, 3 avenue du 8 Mai 1945 and Les Cholettes.

Over the past 12 months ANFR recorded 29 new systems here. ANFR has approved 2 new sites that are not live yet, plus additions on 4 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at Avenue du Stade and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 134 Avenue Gabriel Péri. 25 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (21 of 31), so heights stay modest; the tallest support is 57 m at 1 rue Jean Philippe Rameau.

Systems from 1998 are still on the register. Bouygues Telecom switched on the first 5G here in November 2020; Free Mobile followed in December 2020, SFR followed in March 2021. 2015 was the busiest year, with 64 new systems, most of them 4G.

Among the 43 Val-d'Oise towns with at least five masts, Sarcelles ranks 3rd by mast count. With 31 masts for 59,173 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (6).

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 12 of its 13 masts, Free Mobile on all 12 masts, SFR on all 11 masts and Orange on all 8 masts.

Nearby, Saint-Brice-sous-Foret (1.8 km to the west) has only 13 masts.

8 supports carry only Free Mobile.

At 8 km² with 59,173 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Roissy Pays de France intercommunal grouping.

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