Cell towers in Loos (Nord)

Declared locations include 81 rue Marechal Foch, Fléquières, 1 Rue Jean Zay, Rue des Frères Lumière, Residence Briand and 1 rue Geoges Potié.

2020 was the busiest year, with 43 new systems, most of them 5G. Local 5G started with Orange in November 2020; Bouygues Telecom followed in December 2020, Free Mobile followed in December 2020. The oldest transmitter still listed here goes back to 1993.

Approved additions not yet in service are pending on 4 existing masts, for example Orange (5G, including 5G at 3.5 GHz) at 1 rue Jules Vallès, Orange (5G 700 MHz) at Rue des Frères Lumière and SFR (5G 3.5 GHz) at 81 rue Marechal Foch. 15 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3.5 GHz 5G is declared by Free Mobile on all 8 masts, Bouygues Telecom on 7 of its 8 masts, Orange on 5 of its 6 masts and SFR on 4 of its 6 masts. 100% of the town's masts carry 5G, more than across Nord towns with five or more masts (83%).

13 of the 17 masts are rooftop-mounted. The tallest support is 72 m at Fléquières (radio relay tower). The median is 26 m, slightly below the Nord median of 30 m.

3.7 km to the north-east, neighbouring Lille has 261 masts, more than here.

Supports leave a gap of about 1.5 km to the south-east of the centre.

Of the 17 masts in the commune, only one mast carries all four networks.

By mast count, Loos is 14th of the 94 Nord towns that have five or more. With 17 masts for 22,567 residents, or 8 per 10,000, it has fewer masts per inhabitant than the median for those towns (9).

At 7 km² with 22,567 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Métropole Européenne de Lille intercommunal grouping.

Supports split between 13 buildings, 3 pylons and 1 radio relay tower.
