ANFR has approved one new site that is not live yet. New: Bouygues Telecom (4G and 5G) at 18 rue de Cézembre. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2021 was the busiest year, with 27 new systems, most of them 5G. Local 5G started with Free Mobile in December 2020; Orange followed in March 2021, Bouygues Telecom followed in October 2021. The oldest transmitter still listed here goes back to 2001.

3.5 GHz 5G is declared by Orange on all 4 masts, Free Mobile on 3 of its 4 masts, SFR on all 3 masts and Bouygues Telecom on 2 of its 5 masts. 100% of the town's masts carry 5G, more than across Ille-et-Vilaine towns with five or more masts (82%).

The tallest structure is a 33 m pylon at 18 Rue de Cezembre. The median height of measured supports is 30 m.

3.8 km to the north, neighbouring Cesson-Sevigne has 39 masts, more than here.

Of the 12 masts in the commune, Free Mobile is the only carrier on 3 masts.

By mast count, Chantepie is 6th of the 36 Ille-et-Vilaine towns that have five or more. With 12 masts for 10,670 residents, or 11 per 10,000, it has more masts per inhabitant than the median for those towns (10).

10,670 residents over 12 km²: supports are mostly pylons, not rooftops. It is part of the Rennes Métropole intercommunal grouping.
