Declared supports include 1 camouflaged "tree" pylon and 1 church or religious building, with pylons making up most of the remainder.

8 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on one existing mast. New: Orange (3G, 4G and 5G, including 5G at 3.5 GHz) at Chemin du Bois de Beauvais. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists a 40 m church or religious building at place Notre Dame as the tallest structure. The median is 24 m, slightly below the Calvados median of 31 m.

The commune owns 2 of the 8 masts, TDF owns 1.

2023 was the busiest year, with 17 new systems, most of them 4G. Local 5G started with Free Mobile in April 2021; Orange followed in May 2022, Bouygues Telecom followed in May 2024. The oldest transmitter still listed here goes back to 1997.

3.5 GHz 5G is declared by Bouygues Telecom on 3 of its 4 masts, SFR on 3 of its 4 masts, Free Mobile on all 2 masts and Orange on 1 of its 3 masts. 63% of the town's masts carry 5G, fewer than across Calvados towns with five or more masts (88%).

By mast count, Trouville-sur-Mer is 7th of the 20 Calvados towns that have five or more. With 8 masts for 4,619 residents, or 17 per 10,000, it has more masts per inhabitant than the median for those towns (9).

Nearby, Le Havre (14 km to the north) has 119 masts, more than here.

Of the 8 masts in the commune, 5 of the 8 masts host at least two operators.
