2017 was the busiest year, with 12 new systems, most of them 4G. Local 5G started with Free Mobile in December 2020; Bouygues Telecom followed in September 2021, SFR followed in September 2021. The oldest transmitter still listed here goes back to 2014.

Approved additions not yet in service are pending on 2 existing masts, for example Free Mobile (5G 3.5 GHz) at La Boisselle and Free Mobile (5G 700 MHz) at 1 Rue D'Arnstein. 3 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3.5 GHz 5G is declared by Orange on all 3 masts, Bouygues Telecom on 1 of its 2 masts, Free Mobile on 1 of its 2 masts and SFR on 1 of its 2 masts. 100% of the town's masts carry 5G, more than across Ille-et-Vilaine towns with five or more masts (82%).

Saint-Malo lies 12 km to the west and has 36 masts, more than here.

Supports leave a gap of about 2.7 km to the north of the centre.

By mast count, Cancale is 28th of the 36 Ille-et-Vilaine towns that have five or more. With 5 masts for 5,672 residents, or 9 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).
