Place names on the register include Le Boutras, Badan, 1 Rue Emmanuel Rolland, 4 place Felix Heritier, 20 rue André Sabatier and Avenue Jean Durand.

14 systems were switched on in the past 12 months. ANFR has approved 3 new sites that are not live yet, plus additions on 2 existing masts. New: Bouygues Telecom (4G and 5G) at Chem de Champlevert, Orange (4G and 5G, including 5G at 3.5 GHz) at 1 Rue Marcel Paul and SFR (4G and 5G, including 5G at 3.5 GHz) at 15 avenue Chantelot. 4 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2017 was the busiest year, with 7 new systems, most of them 4G. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in December 2020, Orange followed in September 2021. The oldest transmitter still listed here goes back to 2000.

ANFR lists a 25 m pylon at Badan as the tallest structure. The median height of measured supports is 24 m.

3.5 GHz 5G is declared by Free Mobile on all 3 masts, Bouygues Telecom on all 2 masts, Orange on all 2 masts and SFR on its only mast. 100% of the town's masts carry 5G, more than across Rhône towns with five or more masts (87%).

Nearby, Ternay (1.8 km to the south-east) has 6 masts declared.

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

4 pylons and 3 buildings carry the commune's antennas.
