Cell towers in Rosporden (Finistère)

Declared supports include 1 water tower, with pylons making up most of the remainder.

Place names on the register include Rue du Cimetière, La Grande Boissiere, Coat Cul Oden Vihan, rue de Coat Aven and Kerhuilet.

Inventory: a 40 m pylon, at Rue du Cimetière, for Orange; a 32 m pylon, at La Grande Boissiere, for Bouygues Telecom, Free Mobile and SFR; a 33 m pylon, at Coat Cul Oden Vihan, for Free Mobile; a 28 m pylon, at rue de Coat Aven, for Orange; a 67 m water tower, at Kerhuilet, for Bouygues Telecom, Free Mobile, Orange and SFR.

Only Orange broadcasts 5G at 3.5 GHz here, on all 3 masts. 100% of the town's masts carry 5G, more than across Finistère towns with five or more masts (85%).

2015 was the busiest year, with 7 new systems, most of them 4G. Free Mobile opened 5G here in February 2021; SFR followed in November 2021, Bouygues Telecom followed in November 2021. The oldest transmitter still listed here goes back to 2002.

8 systems were switched on in the past 12 months. Approved additions not yet in service are pending on one existing mast, for example Bouygues Telecom (4G and 5G) at Kerhuilet and SFR (4G and 5G) at Kerhuilet. 1 Bouygues Telecom 5G transmitter is listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists a 67 m water tower at Kerhuilet as the tallest structure. The median height of measured supports is 33 m.

By mast count, Rosporden is 37th of the 38 Finistère towns that have five or more. With 5 masts for 7,550 residents, or 7 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

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

Supports leave a gap of about 2.2 km to the south-west of the centre.

Elliant lies 5.6 km to the north-west and has less 5G (60%).

Of the 5 masts in the commune, only one mast carries all four networks.
