Cell towers in Roost-Warendin (Nord)

Most of the town's 7 masts are pylons (6); 1 historic monument make up the rest of the mix.

Masts stand at Chemin de la Station de Pompage, Le Chevalement, 1545 rue Marcel Sembat, 203 rue Edouard Vaillant, Rue Francisco Ferrer and 943 Rue Voltaire.

Systems from 1998 are still on the register. Local 5G started with Bouygues Telecom in April 2021; SFR followed in April 2021, Free Mobile followed in June 2021. 2021 was the busiest year, with 17 new systems, most of them 5G.

Approved additions not yet in service are pending on one existing mast, for example Free Mobile (5G 700 MHz) at Chemin de la Station de Pompage. 7 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: Bouygues Telecom on 3 of its 4 masts, Orange on all 3 masts, Free Mobile on all 2 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.

ANFR lists a 63 m historic monument at Le Chevalement as the tallest structure. The median height of measured supports is 31 m.

3 supports carry only Bouygues Telecom.

The widest declared gap between neighbouring supports is about 1.6 km, to the west of the centre.

Nearby, Raimbeaucourt (1.9 km to the north-west) has 7 masts declared.

Among the 94 Nord towns with at least five masts, Roost-Warendin ranks 72nd by mast count. With 7 masts for 5,956 residents, or 12 per 10,000, it has more 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.
