Over the past 12 months ANFR recorded 51 new systems here. ANFR has approved 5 new sites that are not live yet, plus additions on 25 existing masts. New: Bouygues Telecom (4G 1800 MHz) at 12 rue de Chateaudun, SFR (4G and 5G, including 5G at 3.5 GHz) at 1 Rue Bourdaloue and SFR (4G and 5G, including 5G at 3.5 GHz) at 15 Rue de Trevise. 32 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Systems from 1996 are still on the register. Bouygues Telecom switched on the first 5G here in January 2021; Orange followed in March 2021, SFR followed in March 2021. 2013 was the busiest year, with 158 new systems, most of them 4G.

Most antennas sit on rooftops (69 of 84), so heights stay modest; the tallest support is 51 m at 40 boulevard Haussmann - Galerie Lafayette.

On 3.5 GHz, the fastest 5G band: Free Mobile on 15 of its 26 masts, Bouygues Telecom on 13 of its 29 masts, Orange on 12 of its 24 masts and SFR on 11 of its 27 masts.

Nearby, Paris 03 Temple (1.8 km to the south-east) has only 39 masts.

Only one mast carries all four networks.

At 2 km² with 57,271 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.
