Cell towers in Arnouville (Val-d'Oise)

Declared supports include 1 water tower, with buildings making up most of the remainder.

Place names on the register include 32 rue Laugère, 92 A et 94 Avenue de la Republique, rue Jean Laugere, 26 rue Marat, 135 rue Jean Jaurès and 91 rue Jean Jaurès.

18 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on one existing mast. New: Bouygues Telecom (4G and 5G) at 136 avenue Charles Vaillant. 8 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

2020 was the busiest year, with 17 new systems, most of them 5G. Bouygues Telecom opened 5G here in November 2020; Free Mobile followed in December 2020, SFR followed in October 2021. The oldest transmitter still listed here goes back to 1996.

7 of the 8 masts are rooftop-mounted. The tallest support is 37 m at 26 rue Marat (water tower). The median is 21 m, slightly below the Val-d'Oise median of 25 m.

3.5 GHz 5G is declared by Bouygues Telecom on all 4 masts, Orange on all 4 masts, Free Mobile on all 3 masts and SFR on all 3 masts.

Nearby, Garges-les-Gonesse (2.2 km to the south-west) has 16 masts, more than here.

Of the 8 masts in the commune, 4 of the 8 masts host at least two operators.

At 3 km² with 15,023 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons.
