Masts stand at 4ter Route de Grenoble 38120 Saint-Égrève, Champaviotte, RTE de Proveysieux, 17 Avenue de l'Ile Brune, Rue des Bonnais and Rue de l Isere.

Over the past 12 months ANFR recorded 12 new systems here. ANFR has approved one new site that is not live yet, plus additions on 3 existing masts. New: Orange (4G and 5G, including 5G at 3.5 GHz) at 6 Place St Christophe. 4 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists a 35 m pylon at L'Ile Brune as the tallest structure. The median is 19 m, slightly below the Isère median of 26 m.

Systems from 2004 are still on the register. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in January 2021, Orange followed in October 2021. 2015 was the busiest year, with 15 new systems, most of them 4G.

3 supports carry only Free Mobile.

On 3.5 GHz, the fastest 5G band: Orange on all 4 masts, Free Mobile on 3 of its 4 masts, SFR on 3 of its 4 masts and Bouygues Telecom on 2 of its 3 masts.

Nearby, Saint-Martin-le-Vinoux (4.3 km to the south-east) has only 6 masts.

Supports split between 6 pylons and 4 buildings.
