Cell towers in Houilles (Yvelines)

Antennas are listed at 41 rue Ernest Renan, 120-122 Boulevard Henri Barbusse, Houilles, 41 Rue du President Kennedy, 50 rue Hoche and 15-31 Rue Robespierre.

Over the past 12 months ANFR recorded 13 new systems here. ANFR has approved one new site that is not live yet, plus additions on 2 existing masts. New: Bouygues Telecom (4G and 5G) at 56 rue Ambroise Croizat. 8 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. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in December 2020, SFR followed in December 2020. 2015 was the busiest year, with 23 new systems, most of them 4G.

Most antennas sit on rooftops (15 of 17), so heights stay modest; the tallest support is 35 m at 50 rue Hoche.

On 3.5 GHz, the fastest 5G band: Free Mobile on all 6 masts, Orange on all 6 masts, SFR on all 4 masts and Bouygues Telecom on 3 of its 5 masts.

Bezons lies 1.5 km to the east and has 20 masts declared.

Only one mast carries all four networks; 5 supports carry only Orange.

At 4 km² with 33,983 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Saint Germain Boucles de Seine intercommunal grouping.

Supports split between 15 buildings and 2 pylons.

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