Cell towers in Brest (Finistère)

Declared supports include 3 water towers, with buildings making up most of the remainder.

Declared locations include Océanopolis, 14 Rue Léon Harmel, 105 Bis rue Jules Lesven, La Cavale Blanche, Les Quatre Moulins and Blv Isidore Marfille.

36 systems were switched on in the past 12 months. ANFR has approved 8 new sites that are not live yet, plus additions on 25 existing masts. New: Bouygues Telecom (4G and 5G) at 8 rue Auguste Kervern, Bouygues Telecom (4G and 5G) at 152 rue Jean Jaurès and Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at 7 rue du Colonel Berthaud. 55 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The commune owns 3 of the 94 masts, Cellnex owns 8.

2013 was the busiest year, with 172 new systems, most of them 4G. Orange switched on the first 5G here in December 2020; Free Mobile followed in December 2020, Bouygues Telecom followed in July 2021. The oldest transmitter still listed here goes back to 1995.

63 of the 94 masts are rooftop-mounted. The tallest support is 67 m at rue du Vercors (radio relay tower). The median is 29 m, slightly below the Finistère median of 32 m.

Of the 94 masts in the commune, 2 masts carry all four networks.

By mast count, Brest is 1st of the 38 Finistère towns that have five or more. With 94 masts for 142,346 residents, or 7 per 10,000, it has fewer masts per inhabitant than the median for those towns (10).

3.5 GHz 5G is declared by Orange on 32 of its 37 masts, SFR on 32 of its 36 masts, Bouygues Telecom on 21 of its 35 masts and Free Mobile on 18 of its 29 masts.

6.8 km to the north-west, neighbouring Guilers has only 7 masts.

At 49 km² with 142,346 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Brest Métropole intercommunal grouping.
