Cell towers in Epinay-sur-Orge (Essonne)

Most of the town's 10 masts are pylons (5); 1 camouflaged "tree" pylon make up the rest of the mix.

Masts stand at rue Pierre Mederic, Prairie de Rossay, Les Froids Culs, 134-136 Grande Rue, 2 rue de Charaintru and rue de Charaintru.

ANFR has approved one new site that is not live yet, plus additions on 2 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 4 Rue de Mauregard. 10 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Systems from 2000 are still on the register. Free Mobile switched on the first 5G here in December 2020; SFR followed in March 2021, Bouygues Telecom followed in December 2021. 2020 was the busiest year, with 32 new systems, most of them 4G.
