Cell towers in Maisons-Laffitte (Yvelines)

2 water towers and 5 buildings, 1 church or religious building and 1 pylon carry the commune's antennas.

Antennas are listed at 13 Rue de la Muette, Stade Desaix, 10 Rue de la Passerelle, avenue Jacques Laffitte, 20 Rue de Paris and 54 rue du Tir.

ANFR has approved one new site that is not live yet, plus additions on one existing mast. New: SFR (3G, 4G and 5G, including 5G at 3.5 GHz) at 8 Residence Desaix. 10 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 opened 5G here in November 2020; Free Mobile followed in December 2020, Orange followed in June 2021. 2014 was the busiest year, with 29 new systems, most of them 4G.

ANFR lists a 50 m church or religious building at 13 Rue de la Muette as the tallest structure. The median is 29 m, above the Yvelines median of 25 m.

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

Sartrouville lies 3.4 km to the east and has 32 masts, more than here.

The widest declared gap between neighbouring supports is about 1.5 km, to the north-east of the centre.

Only one mast carries all four networks.

Among the 62 Yvelines towns with at least five masts, Maisons-Laffitte ranks 33rd by mast count. With 9 masts for 23,093 residents, or 4 per 10,000, it has fewer masts per inhabitant than the median for those towns (7).

At 7 km² with 23,093 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.
