Cell towers in Besancon (Doubs)

The widest declared gap between neighbouring supports is about 2.4 km, to the north of the centre. 2 supports are declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

Most of the town's 84 masts are buildings (50); 2 underground or tunnel sites, 2 churches or religious buildings and 1 camouflaged "tree" pylon make up the rest of the mix.

Antennas are listed at Forêt de Chailluz, 132 rue de Belfort, Bregille, Les Graviers Blancs, Quartier St Claude and Complexe Sportif de Rosemont.

The tallest structure is a 47 m pylon at Bregille. The median is 25 m, slightly below the Doubs median of 30 m.

Over the past 12 months ANFR recorded 74 new systems here. ANFR has approved 2 new sites that are not live yet, plus additions on 15 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 36 Rue Romain Roussel. 42 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

12 masts belong to the commune itself and 7 to On Tower France; the rest sit mainly on private buildings.

Systems from 1995 are still on the register. Free Mobile switched on the first 5G here in December 2020; SFR followed in August 2021, Bouygues Telecom followed in August 2021. 2018 was the busiest year, with 196 new systems, most of them 4G.

6 masts carry all four networks; 25 supports carry only Orange.

Among the 9 Doubs towns with at least five masts, Besancon ranks 1st by mast count. With 84 masts for 118,489 residents, or 7 per 10,000, it has fewer masts per inhabitant than the median for those towns (9).

On 3.5 GHz, the fastest 5G band: Orange on 32 of its 38 masts, Free Mobile on 25 of its 34 masts, SFR on 19 of its 33 masts and Bouygues Telecom on 18 of its 32 masts.

Baume-les-Dames lies 28 km to the north-east and has only 8 masts.

At 65 km² with 118,489 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CU Grand Besançon Métropole intercommunal grouping.

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