ANFR has approved one new site that is not live yet. New: Bouygues Telecom (3G, 4G and 5G) at RTE du Peuil. 4 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists a 68 m pylon at Dessus de Jayères as the tallest structure. The median height of measured supports is 27 m.

2023 was the busiest year, with 10 new systems, most of them 4G. Orange switched on the first 5G here in October 2021; Free Mobile followed in October 2022, SFR followed in February 2023. The oldest transmitter still listed here goes back to 2013.

On Tower France is the largest declared owner (2 masts), ahead of Totem (1).

3.5 GHz 5G is declared by Bouygues Telecom on all 2 masts, Free Mobile on 1 of its 2 masts, Orange on 1 of its 2 masts and SFR on its only mast.

Echirolles lies 4.4 km to the north-east and has 22 masts, more than here.

By mast count, Claix is 34th of the 43 Isère towns that have five or more. With 5 masts for 7,836 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (9).
