Cell towers in Taverny (Val-d'Oise)

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

2 underground or tunnel sites and 13 buildings, 5 pylons and 1 camouflaged "tree" pylon carry the commune's antennas.

Antennas are listed at avenue de la Division Leclerc, 8 Place des Sept Fontaines, 2 place Charles de Gaulle, Ccal Auchan, Les Fréchaux and 8 allée des Troènes.

Systems from 1996 are still on the register. Bouygues Telecom switched on the first 5G here in December 2020; Free Mobile followed in April 2021, SFR followed in July 2021. 2014 was the busiest year, with 31 new systems, most of them 4G.

Over the past 12 months ANFR recorded 24 new systems here. Approved additions not yet in service are pending on 7 existing masts, for example Bouygues Telecom (4G 1800 MHz) at Ccal Auchan, Bouygues Telecom (4G 2100 MHz) at 12 rue Jean Macé and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at Allee des Nerins. 14 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (13 of 21), so heights stay modest; the tallest support is 38 m at 8 allée des Troènes.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 7 of its 9 masts, Orange on 5 of its 6 masts, Free Mobile on 4 of its 6 masts and SFR on 3 of its 6 masts.

Beauchamp lies 1.6 km to the south-west and has only 5 masts.

Among the 43 Val-d'Oise towns with at least five masts, Taverny ranks 7th by mast count. With 21 masts for 27,593 residents, or 8 per 10,000, it has more masts per inhabitant than the median for those towns (6).

At 10 km² with 27,593 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Val Parisis intercommunal grouping.

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