Cell towers in Chalons-en-Champagne (Marne)

Antennas are listed at La Côte Mahout, Les Escarnotières, Le Mont Hery, 3 Rue Denis Papin - ZAC des Escarnotières, 9 rue de St Malo and Rue des Brasseries.

Over the past 12 months ANFR recorded 17 new systems here. ANFR has approved one new site that is not live yet, plus additions on 4 existing masts. New: SFR (4G and 5G, including 5G at 3.5 GHz) at 31 Chaussee du Port. 9 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Systems from 1995 are still on the register. Free Mobile switched on the first 5G here in December 2020; Orange followed in December 2022, SFR followed in August 2023. 2016 was the busiest year, with 64 new systems, most of them 4G.

On 3.5 GHz, the fastest 5G band: Free Mobile on 12 of its 14 masts, Orange on 12 of its 16 masts, Bouygues Telecom on 4 of its 9 masts and SFR on 4 of its 10 masts. 5G is on 73% of masts here, against 88% across Marne towns with five or more masts.

Most antennas sit on rooftops (17 of 26), so heights stay modest; the tallest support is 67 m at 9 rue de St Malo.

4 masts carry all four networks.

Among the 14 Marne towns with at least five masts, Chalons-en-Champagne ranks 2nd by mast count. With 26 masts for 42,971 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (11).

27 km to the west, neighbouring Vertus has only 5 masts.

The widest declared gap between neighbouring supports is about 2.6 km, to the north-east of the centre.

At 26 km² with 42,971 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA de Châlons-en-Champagne intercommunal grouping.

Supports split between 17 buildings and 9 pylons.

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