Cell towers in Leers (Nord)

1 church or religious building and 6 pylons, 1 mast and 1 building carry the commune's antennas.

Masts stand at rue Mirabeau Usine de Leers, 68 Brue de Lys, Le Coulombier, 66 Allée du Coulombier, place Lucien Demonchaux and rue de la Plaine.

2 masts belong to the commune itself and 1 to Hivory; the rest sit mainly on private buildings.

Systems from 1998 are still on the register. Bouygues Telecom opened 5G here in November 2020; Free Mobile followed in December 2020, SFR followed in March 2021. 2013 was the busiest year, with 16 new systems, most of them 4G.

Over the past 12 months ANFR recorded 9 new systems here. Approved additions not yet in service are pending on 3 existing masts, for example Bouygues Telecom (5G 3.5 GHz) at 68 Brue de Lys, Free Mobile (5G 700 MHz) at 66 Allée du Coulombier and SFR (5G 2100 MHz) at rue Mirabeau Usine de Leers. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

On 3.5 GHz, the fastest 5G band: Free Mobile on all 4 masts, Orange on all 4 masts, Bouygues Telecom on 2 of its 4 masts and SFR on 1 of its 2 masts. 5G is on 100% of masts here, against 83% across Nord towns with five or more masts.

The highest support stands 42 m at place Lucien Demonchaux (church or religious building). The median height of measured supports is 30 m.

3 supports carry only Bouygues Telecom.

2.5 km to the south, neighbouring Toufflers has only 6 masts.

Figures above cover installations declared to ANFR as in service or technically operational, as of October 2026; approved projects are not counted.
