Cell towers in Echirolles (Isère)

Antennas are listed at La Luire, 3 Rue Gabriel Didier, Les Granges, 119 Cours Jean Jaurès, 1/3 avenue Daniel Casanova and 3 Rue de Comboire.

Over the past 12 months ANFR recorded 12 new systems here. ANFR has approved 3 new sites that are not live yet, plus additions on 4 existing masts. New: Bouygues Telecom (4G and 5G) at 10-14 Avenue des États Généraux, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 1 Allee Eugene Sue and SFR (3G, 4G and 5G, including 5G at 3.5 GHz) at 7 Rue Commandant Lenoir. 17 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 Bouygues Telecom in November 2020; Free Mobile followed in December 2020, Orange followed in October 2021. 2014 was the busiest year, with 30 new systems, most of them 4G.

Among the 43 Isère towns with at least five masts, Echirolles ranks 3rd by mast count. With 22 masts for 37,491 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (9).

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 8 of its 9 masts, SFR on all 7 masts, Free Mobile on 6 of its 7 masts and Orange on all 6 masts.

ANFR lists a 66 m building as the tallest structure. The median height of measured supports is 27 m.

Eybens lies 2.8 km to the east and has only 6 masts.

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

At 8 km² with 37,491 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Grenoble-Alpes-Métropole intercommunal grouping.

Most of the town's 22 masts are buildings (13).

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