Cell towers in Bievres (Essonne)

Most of the town's 11 masts are buildings (5); 1 camouflaged "tree" pylon make up the rest of the mix.

Place names on the register include Chemin de la Porte Jaune, Domaine du Bel Air, 21 RTE de Gizy, Les Hommeries, Le Cottage and RTE de Jouy - Ech N444/N118.

ANFR lists a 41 m pylon at 125 Rue de Paris as the tallest structure. The median height of measured supports is 26 m.

2014 was the busiest year, with 16 new systems, most of them 4G. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in December 2020, Orange followed in April 2023. The oldest transmitter still listed here goes back to 1996.

10 systems were switched on in the past 12 months. Approved additions not yet in service are pending on 5 existing masts, for example Bouygues Telecom (5G 3.5 GHz), Bouygues Telecom (4G and 5G) at rue du Chat Noir and Bouygues Telecom (4G and 5G) at Chemin de la Porte Jaune. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3.5 GHz 5G is declared by Free Mobile on all 4 masts, Orange on all 4 masts, Bouygues Telecom on 2 of its 6 masts and SFR on 1 of its 3 masts. 64% of the town's masts carry 5G, fewer than across Essonne towns with five or more masts (88%).

Of the 11 masts in the commune, Bouygues Telecom is the only carrier on 4 masts.

By mast count, Bievres is 30th of the 60 Essonne towns that have five or more. With 11 masts for 4,686 residents, or 23 per 10,000, it has more masts per inhabitant than the median for those towns (7).

Velizy-Villacoublay lies 3.3 km to the north-west and has 23 masts, more than here.
