Cell towers in Pessac (Gironde)

Most of the town's 34 masts are buildings (20); 1 camouflaged "tree" pylon make up the rest of the mix.

Antennas are listed at 4 Avenue Diderot, 1 avenue de Magellan, 42-44 avenue de la Châtaigneraie, avenue de Magellan, 8 Avenue Antoine Becquerel and Bois des Sources du Peugue.

Over the past 12 months ANFR recorded 40 new systems here. ANFR has approved 5 new sites that are not live yet, plus additions on 16 existing masts. New: Bouygues Telecom (4G and 5G) at 7 avenue du Stade, Bouygues Telecom (4G and 5G) at 21 rue Felix Leroy and Bouygues Telecom (3G, 4G and 5G, including 5G at 3.5 GHz) at 4 Allée des Forsythias. 28 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Systems from 1997 are still on the register. Local 5G started with SFR in December 2020; Free Mobile followed in December 2020, Bouygues Telecom followed in December 2020. 2013 was the busiest year, with 103 new systems, most of them 4G.

ANFR lists a 73 m building at 2 allée des Forsythias as the tallest structure. The median is 32 m, slightly below the Gironde median of 36 m.

2 masts carry all four networks; 9 supports carry only Bouygues Telecom.

Among the 62 Gironde towns with at least five masts, Pessac ranks 3rd by mast count. With 34 masts for 67,339 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

On 3.5 GHz, the fastest 5G band: Free Mobile on all 15 masts, Orange on all 13 masts, Bouygues Telecom on 12 of its 16 masts and SFR on 8 of its 10 masts.

The widest declared gap between neighbouring supports is about 2.1 km, to the south-west of the centre.

Nearby, Talence (3.4 km to the east) has 33 masts declared.

At 39 km² with 67,339 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Bordeaux 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.
