2022 was the busiest year, with 15 new systems, most of them 5G. Free Mobile opened 5G here in December 2020; SFR followed in February 2022, Bouygues Telecom followed in February 2022. The oldest transmitter still listed here goes back to 1998.

8 systems were switched on in the past 12 months. Approved additions not yet in service are pending on 2 existing masts, for example Free Mobile (4G and 5G, including 5G at 3.5 GHz) at Le Clos du Pré Moal and Free Mobile (5G 700 MHz) at Terrain de Tennis. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3.5 GHz 5G is declared by Bouygues Telecom on all 3 masts, Orange on all 3 masts, SFR on all 3 masts and Free Mobile on all 2 masts. 100% of the town's masts carry 5G, more than across Côtes-d'Armor towns with five or more masts (86%).

Supports leave a gap of about 1.6 km to the north-east of the centre.

7.2 km to the east, neighbouring Frehel has 6 masts declared.

Of the 6 masts in the commune, 4 of the 6 masts host at least two operators.
