2020 was the busiest year, with 10 new systems, most of them 5G. Local 5G started with Orange in November 2020; Free Mobile followed in December 2020, Bouygues Telecom followed in April 2021. The oldest transmitter still listed here goes back to 2007.

Approved additions not yet in service are pending on one existing mast, for example Orange (5G 700 MHz) at Chemin du Plessis. 2 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The highest support stands 35 m at Chemin des Grands Plessis (pylon). The median is 28 m, slightly below the Sarthe median of 33 m.

By mast count, Coulaines is 11th of the 16 Sarthe towns that have five or more. With 5 masts for 8,121 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (13).

On Tower France is the largest declared owner (2 masts), ahead of Totem (1).

3.5 GHz 5G is declared by Free Mobile on all 2 masts, Orange on all 2 masts, Bouygues Telecom on its only mast and SFR on 1 of its 2 masts.

2.4 km to the south, neighbouring Le Mans has 114 masts, more than here.

Most of the town's 5 masts are pylons (4).
