Cell towers in Freneuse (Yvelines)

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 4 pylons and 1 building carry the commune's antennas.

Declared locations include 2 D Route Departementale 113, Bois Prevost, Les Coutumes, 1 Rue des Bouderies, La Croix du Moulin and 6 Rue des Alpes.

ANFR has approved one new site that is not live yet, plus additions on 2 existing masts. New: Orange (3G and 4G) at Le Galicet. 2 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2018 was the busiest year, with 23 new systems, most of them 4G. Free Mobile switched on the first 5G here in December 2020; Orange followed in June 2022, SFR followed in December 2023. The oldest transmitter still listed here goes back to 2000.

3.5 GHz 5G is declared by Orange on all 4 masts, Bouygues Telecom on 1 of its 4 masts, Free Mobile on 1 of its 3 masts and SFR on 1 of its 5 masts. 71% of the town's masts carry 5G, fewer than across Yvelines towns with five or more masts (88%).

ANFR lists a 32 m pylon at 1 Rue des Bouderies as the tallest structure. The median is 29 m, above the Yvelines median of 25 m.

Of the 7 masts in the commune, 2 masts carry all four networks.

By mast count, Freneuse is 41st of the 62 Yvelines towns that have five or more. With 7 masts for 4,505 residents, or 16 per 10,000, it has more masts per inhabitant than the median for those towns (7).

Nearby, Rosny-sur-Seine (6 km to the south) has 5 masts declared.
