Cell towers in Saint-Jean (Haute-Garonne)

Masts stand at Borde Neuve, Chem de Belbeze, Mas de Las Planes, avenue de l'Eglise - place de la Mairie, 9002 Chem de Belbeze and Le Cassé.

4 masts belong to the commune itself and 1 to Hivory; the rest sit mainly on private buildings.

Systems from 2007 are still on the register. SFR opened 5G here in September 2021; Bouygues Telecom followed in October 2021, Free Mobile followed in December 2021. 2021 was the busiest year, with 14 new systems, most of them 5G.

Approved additions not yet in service are pending on 3 existing masts, for example Free Mobile (5G 700 MHz) at Mas de Las Planes, SFR (5G 2100 MHz) at Le Cassé and SFR (5G 2100 MHz) at Chem de Belbeze. 5 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The tallest structure is a 38 m pylon at Le Cassé. The median is 25 m, slightly below the Haute-Garonne median of 30 m.

3 supports carry only Bouygues Telecom.

On 3.5 GHz, the fastest 5G band: Free Mobile on all 3 masts, Orange on all 3 masts, Bouygues Telecom on 2 of its 3 masts and SFR on all 2 masts.

6.5 km to the north-west, neighbouring Castelginest has less 5G (86%).

Most declared azimuths point outward, along a corridor or valley rather than at the centre.

6 pylons and 3 buildings carry the commune's antennas.

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