Cell towers in Hem (Nord)

Most of the town's 15 masts are pylons (7); 1 water tower make up the rest of the mix.

Antennas are listed at avenue du Dr Schweitzer, Complexe Sportif G. Dubus, avenue Antoine Pinay, Rue de Beaumont, 231 Avenue Charles de Gaulle and Avenue Henri Delevroix.

Systems from 1995 are still on the register. Free Mobile opened 5G here in December 2020; Bouygues Telecom followed in May 2021, SFR followed in June 2022. 2021 was the busiest year, with 30 new systems, most of them 5G.

Over the past 12 months ANFR recorded 10 new systems here. Approved additions not yet in service are pending on 2 existing masts, for example Bouygues Telecom (5G 3.5 GHz) at rue de la Vallée and SFR (5G 2100 MHz). 11 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 5 masts, Bouygues Telecom on 4 of its 7 masts, Orange on all 4 masts and SFR on 3 of its 4 masts. 5G is on 100% of masts here, against 83% across Nord towns with five or more masts.

Toufflers lies 3.4 km to the east and has only 6 masts.

The highest support stands 43 m (building). The median is 26 m, slightly below the Nord median of 30 m.

Only one mast carries all four networks; 4 supports carry only Bouygues Telecom.

Among the 94 Nord towns with at least five masts, Hem ranks 20th by mast count. With 15 masts for 18,582 residents, or 8 per 10,000, it has fewer masts per inhabitant than the median for those towns (9).

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