Cell towers in Morangis (Essonne)

1 camouflaged "tree" pylon and 5 buildings and 3 pylons carry the commune's antennas.

Antennas are listed at La Croix Boisselière, 3 rue du Dr Albert Schweitzer, 110 avenue de la Republique, 99 avenue Charles de Gaulle, 2 rue de l'Ormeteau and 6 rue de l'Ormeteau.

ANFR has approved one new site that is not live yet, plus additions on one existing mast. New: Orange (4G and 5G, including 5G at 3.5 GHz) at Rue Nicéphore Niepce. 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. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in December 2020, SFR followed in June 2021. 2021 was the busiest year, with 19 new systems, most of them 5G.

ANFR lists a 29 m building at 2 rue de l'Ormeteau as the tallest structure. The median height of measured supports is 25 m.

4 supports carry only Bouygues Telecom.

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

2.1 km to the north-west, neighbouring Chilly-Mazarin has less 5G (78%).

At 5 km² with 14,129 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons.

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