Cell towers in Leognan (Gironde)

1 water tower and 8 pylons, 2 buildings and 1 road gantry carry the commune's antennas.

Place names on the register include Rambaud, La Tuilerie, Domaine du Luc, 102 Chem de Mignoy, Le Brigaillet-la Caze and La Saussette.

13 systems were switched on in the past 12 months. ANFR has approved 2 new sites that are not live yet, plus additions on 3 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at cours du Marechal de Lattre de Tassigny and SFR (4G and 5G, including 5G at 3.5 GHz) at Chemin de Loustalade. 9 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2018 was the busiest year, with 19 new systems, most of them 4G. Bouygues Telecom switched on the first 5G here in January 2021; Free Mobile followed in July 2021, Orange followed in January 2023. The oldest transmitter still listed here goes back to 1995.

The tallest structure is a 51 m water tower at Le Brigaillet-la Caze. The median is 32 m, slightly below the Gironde median of 36 m.

Of the 13 masts in the commune, Orange is the only carrier on 5 masts.

3.5 GHz 5G is declared by Orange on 5 of its 8 masts, Bouygues Telecom on 4 of its 5 masts, SFR on all 4 masts and Free Mobile on its only mast. 77% of the town's masts carry 5G, fewer than across Gironde towns with five or more masts (89%).

5.1 km to the north, neighbouring Gradignan has a higher 5G share (100%).

10,670 residents over 42 km²: supports are mostly pylons, not rooftops. It is part of the CC de Montesquieu intercommunal grouping.
