Cell towers in Lorient (Morbihan)

Declared locations include Le Moustoir, rue de Carnel, 50 rue du Port, 18 Rue Maurice Thorez, 28 rue de Kérulvé and 1 rue de Guéméné.

9 systems were switched on in the past 12 months. ANFR has approved 2 new sites that are not live yet, plus additions on 7 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 19 Rue de Kerfichant and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 9 Rue Président John Kennedy. 11 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2021 was the busiest year, with 49 new systems, most of them 5G. Free Mobile opened 5G here in December 2020; Bouygues Telecom followed in September 2021, SFR followed in September 2021. The oldest transmitter still listed here goes back to 1998.

14 of the 18 masts are rooftop-mounted. The tallest support is 61 m at 1 rue de Guéméné (building). The median height of measured supports is 37 m.

Of the 18 masts in the commune, 2 masts carry all four networks, and Orange is the only carrier on 7 masts.

By mast count, Lorient is 2nd of the 35 Morbihan towns that have five or more. With 18 masts for 58,329 residents, or 3 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

3.5 GHz 5G is declared by Free Mobile on 7 of its 9 masts, Orange on 7 of its 10 masts, Bouygues Telecom on 4 of its 7 masts and SFR on 4 of its 7 masts.

Lanester lies 2.9 km to the north-east and has only 12 masts.

At 15 km² with 58,329 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Lorient Agglomération intercommunal grouping.

Supports split between 14 buildings, 3 pylons and 1 mast.
