Cell towers in Ostwald (Bas-Rhin)

Most of the town's 10 masts are buildings (5); 1 church or religious building make up the rest of the mix.

Masts stand at Aire de Service D'Ostwald Est, Wickenau, 2 rue de Nancy, 5 Rue de la Chapelle, 17 allée Rene Cassin and 7 rue Theodore Monod.

Systems from 1998 are still on the register. Local 5G started with Bouygues Telecom in October 2021; SFR followed in October 2021, Orange followed in January 2022. 2021 was the busiest year, with 15 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 3 existing masts, for example SFR (5G 2100 MHz) at 6 rue D'Eschau, SFR (5G 2100 MHz) at 17 allée Rene Cassin and SFR (4G and 5G, including 5G at 3.5 GHz) at 5 Rue de la Chapelle. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3 supports carry only Bouygues Telecom.

On 3.5 GHz, the fastest 5G band: Orange on all 5 masts, Bouygues Telecom on all 3 masts, SFR on all 3 masts and Free Mobile on all 2 masts. 5G is on 100% of masts here, against 87% across Bas-Rhin towns with five or more masts.

Nearby, Illkirch-Graffenstaden (1.7 km to the south) has 23 masts, more than here.

The highest support stands 43 m (building). The median height of measured supports is 30 m.

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