Cell towers in Huez (Isère)

Declared locations include Le Reservoir, L Alpe D.huez, Lac Blanc et l'Herpie, 75 Avenue des Jeux, En Pierrichard and Les Bergers.

ANFR lists a 40 m pylon at Lac Blanc et l'Herpie as the tallest structure. The median height of measured supports is 25 m.

2018 was the busiest year, with 23 new systems, most of them 4G. Local 5G started with Orange in December 2020; Free Mobile followed in December 2020, SFR followed in September 2022. The oldest transmitter still listed here goes back to 1999.

Approved additions not yet in service are pending on one existing mast, for example Free Mobile (5G 700 MHz) at 75 Avenue des Jeux. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Of the 9 masts in the commune, only one mast carries all four networks, and Orange is the only carrier on 3 masts.

By mast count, Huez is 13th of the 43 Isère towns that have five or more.

3.5 GHz 5G is declared by Free Mobile on 4 of its 5 masts, Bouygues Telecom on all 3 masts, Orange on 3 of its 5 masts and SFR on all 3 masts.

Supports leave a gap of about 3.8 km to the north-east of the centre.

Nearby, Le Versoud (22 km to the north-west) has only 5 masts.

Supports split between 5 buildings and 4 pylons.
