Cell towers in Fontainebleau (Seine-et-Marne)

1 water tower and 6 buildings and 4 pylons carry the commune's antennas.

Masts stand at Gorges et Platrières D'Apremont, La Croix de Franchard, avenue de Thomery, RTE de Buffon, La Butte Montceau and 69 rue Grande (club Bouygtel).

Over the past 12 months ANFR recorded 18 new systems here. ANFR has approved one new site that is not live yet. New: SFR (3G and 4G) at La Plaine de Bois le Roi. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2 masts belong to the commune itself and 2 to TDF; the rest sit mainly on private buildings.

Systems from 1995 are still on the register. Local 5G started with Free Mobile in December 2020; Orange followed in July 2021, SFR followed in October 2022. 2016 was the busiest year, with 40 new systems, most of them 4G.

4 masts carry all four networks.

ANFR lists a 63 m building as the tallest structure. The median is 37 m, above the Seine-et-Marne median of 31 m.

The widest declared gap between neighbouring supports is about 3.8 km, to the west of the centre. Most declared azimuths point outward, along a corridor or valley rather than at the centre.

On 3.5 GHz, the fastest 5G band: Orange on 8 of its 9 masts, Free Mobile on 4 of its 5 masts, Bouygues Telecom on 2 of its 8 masts and SFR on 2 of its 7 masts.

Nearby, Bois-le-Roi (7.2 km to the north) has only 5 masts.

Figures above cover installations declared to ANFR as in service or technically operational, as of October 2026; approved projects are not counted.
