Cell towers in Saint-Dizier (Haute-Marne)

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

Place names on the register include 1 Rue Jean Jacques Rousseau, Avenue Jean-Pierre Timbaud, rue du Puits Royau, 20 Av. des États Unis, 2 rue Marc Séguin and 1 rue Michelet.

13 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on 5 existing masts. New: SFR (4G and 5G, including 5G at 3.5 GHz) at 24 Avenue des Etats-Unis. 5 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2021 was the busiest year, with 34 new systems, most of them 4G. Free Mobile switched on the first 5G here in December 2020; Orange followed in January 2022, SFR followed in August 2023. The oldest transmitter still listed here goes back to 1997.

3.5 GHz 5G is declared by Orange on all 11 masts, Free Mobile on all 8 masts, Bouygues Telecom on 3 of its 5 masts and SFR on 3 of its 5 masts. 94% of the town's masts carry 5G, more than across Haute-Marne towns with five or more masts (75%).

Of the 18 masts in the commune, only one mast carries all four networks, and Orange is the only carrier on 7 masts.

By mast count, Saint-Dizier is 1st of the 5 Haute-Marne towns that have five or more. With 18 masts for 22,858 residents, or 8 per 10,000, it has fewer masts per inhabitant than the median for those towns (12).

22 km to the north-east, neighbouring Bar-le-Duc has only 13 masts.

The highest support stands 74 m (building). The median height of measured supports is 34 m.
