23 of the 36 masts are rooftop-mounted. The tallest support is 72 m at La Ville Besnard (pylon). The median is 22 m, slightly below the Ille-et-Vilaine median of 33 m.

28 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on 9 existing masts. New: Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at 7 rue des Bas Sablons and SFR (4G and 5G, including 5G at 3.5 GHz) at 7 rue des Bas Sablons. 24 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2021 was the busiest year, with 81 new systems, most of them 5G. Free Mobile switched on the first 5G here in December 2020; Orange followed in July 2021, Bouygues Telecom followed in August 2021. The oldest transmitter still listed here goes back to 1997.
