Cell towers in Ensisheim (Haut-Rhin)

Most of the town's 8 masts are pylons (3); 1 water tower, 1 silo and 1 church or religious building make up the rest of the mix.

Antennas are listed at Ensisheim Cité, Grosses St Johannesfeld, place de l'Eglise, RTE de Ungersheim, Fosshag and 2 place Ste Therese.

Systems from 1997 are still on the register. Free Mobile switched on the first 5G here in August 2021; SFR followed in April 2023, Bouygues Telecom followed in July 2023. 2023 was the busiest year, with 32 new systems, most of them 5G.

Over the past 12 months ANFR recorded 13 new systems here. Approved additions not yet in service are pending on one existing mast, for example Bouygues Telecom (2G 900 MHz) at 2 place Ste Therese. 7 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The tallest structure is a 51 m church or religious building at place de l'Eglise. The median height of measured supports is 30 m.

3 supports carry only Orange.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 3 of its 4 masts, SFR on 3 of its 4 masts, Orange on 2 of its 3 masts and Free Mobile on 1 of its 2 masts.

The widest declared gap between neighbouring supports is about 3 km, to the south of the centre.

Pulversheim lies 4.8 km to the south-west and has only 5 masts.

Among the 18 Haut-Rhin towns with at least five masts, Ensisheim ranks 8th by mast count. With 8 masts for 7,306 residents, or 11 per 10,000, it has more masts per inhabitant than the median for those towns (8).

7,306 residents over 37 km²: supports are mostly pylons, not rooftops.

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