Cell towers in Nanterre (Hauts-de-Seine)

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

Most of the town's 67 masts are buildings (52); 10 underground or tunnel sites make up the rest of the mix.

Antennas are listed at Le Petit Nanterre, Tunnel A14 - la Defense, A86 -Tunnel de Nanterre Centre, Tunnel Nanterre A86, Les Provinces Francaises and boulevard des Provinces Francaises.

Over the past 12 months ANFR recorded 37 new systems here. ANFR has approved 6 new sites that are not live yet, plus additions on 16 existing masts. New: Bouygues Telecom (4G and 5G) at 42 à 46 rue Salvador Allende, Free Mobile (4G and 5G) at 19 Rue Salvador Allende and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 440 boulevard des Provinces Francaise. 45 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Systems from 1994 are still on the register. Bouygues Telecom opened 5G here in November 2020; SFR followed in December 2020, Orange followed in December 2020. 2020 was the busiest year, with 148 new systems, most of them 5G.

Most antennas sit on rooftops (52 of 67), so heights stay modest; the tallest support is 64 m at 130 rue du 8 Mai 1945.

Among the 36 Hauts-de-Seine towns with at least five masts, Nanterre ranks 3rd by mast count. With 67 masts for 97,783 residents, or 7 per 10,000, it has more masts per inhabitant than the median for those towns (6).

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 22 of its 31 masts, Free Mobile on 20 of its 24 masts, Orange on 20 of its 25 masts and SFR on 14 of its 22 masts.

Nearby, Rueil-Malmaison (2.1 km to the south-west) has a higher 5G share (90%).

Only one mast carries all four networks.

At 12 km² with 97,783 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.
