Cell towers in Rueil-Malmaison (Hauts-de-Seine)

Most declared azimuths point outward, along a corridor or valley rather than at the centre. 3 supports are declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

Most of the town's 52 masts are buildings (47); 3 underground or tunnel sites, 1 road gantry and 1 camouflaged "tree" pylon make up the rest of the mix.

Declared locations include Tunnel A86, rue du Commandant Jacquot, Avenue du Marechal de Lattre de Tassigny, Rueil Sur Seine, 4 Rue Jacques Daguerre and Résidence les Taratres.

2013 was the busiest year, with 105 new systems, most of them 4G. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in December 2020, SFR followed in January 2021. The oldest transmitter still listed here goes back to 1995.

28 systems were switched on in the past 12 months. Approved additions not yet in service are pending on 17 existing masts, for example Bouygues Telecom (2G 900 MHz) at 53 rue Henri Dunant, Bouygues Telecom (5G 3.5 GHz) at 20 avenue du Marechal de Lattre de Tassigny and Free Mobile (4G and 5G, including 5G at 3.5 GHz). 35 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

47 of the 52 masts are rooftop-mounted. The tallest support is 51 m at 35 B Rue des Mazurieres (building). The median height of measured supports is 25 m.

Of the 52 masts in the commune, 2 masts carry all four networks, and Bouygues Telecom is the only carrier on 13 masts.

3.5 GHz 5G is declared by Bouygues Telecom on 15 of its 22 masts, Free Mobile on 15 of its 19 masts, Orange on 13 of its 18 masts and SFR on 13 of its 17 masts.

Nanterre lies 2.1 km to the north-east and has 67 masts, more than here.

By mast count, Rueil-Malmaison is 5th of the 36 Hauts-de-Seine towns that have five or more.

At 15 km² with 82,874 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.
