Cell towers in L'Hay-les-Roses (Val-de-Marne)

1 support is declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

Most of the town's 20 masts are buildings (14); 3 road gantries, 1 church or religious building and 1 underground or tunnel site make up the rest of the mix.

Declared locations include 18 Rue Henri Thirard, Métro l'Hay les Roses L17, 2 rue Leon Blum (la Vall des Renards Rpa), Les Blondeaux, 1-3 allée Pierre Mendes-France and 22 Rue Gustave Charpentier.

23 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on 6 existing masts. New: Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at 3 Allée des Pervenches. 14 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The commune owns 2 of the 20 masts, Cellnex owns 1.

2018 was the busiest year, with 53 new systems, most of them 4G. Local 5G started with Bouygues Telecom in November 2020; Orange followed in December 2020, Free Mobile followed in December 2020. The oldest transmitter still listed here goes back to 1997.

14 of the 20 masts are rooftop-mounted. The tallest support is 56 m at 8 rue Gustave Charpentier (building). The median is 21 m, slightly below the Val-de-Marne median of 25 m.

3.5 GHz 5G is declared by Bouygues Telecom on 7 of its 9 masts, Free Mobile on 7 of its 8 masts, Orange on 4 of its 7 masts and SFR on 3 of its 5 masts.

Nearby, Bourg-la-Reine (1.4 km to the west) has only 10 masts.

Of the 20 masts in the commune, only one mast carries all four networks.

At 4 km² with 31,188 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.
