Declared locations include Aéroport du Bourget, Aéroport le Bourget, 11 Rue Louise Michel, Parc des Expositions, 1 Avenue de la 2éme Division Blindée and 1 avenue de la 2ème Division Blindée.

30 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on 4 existing masts. New: SFR (3G, 4G and 5G, including 5G at 3.5 GHz) at 6 Rue Louis Pasteur. 9 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

14 of the 20 masts are rooftop-mounted. The tallest support is 38 m at Aeroport du Bourget (pylon). The median is 20 m, slightly below the Seine-Saint-Denis median of 25 m.

The commune owns 3 of the 20 masts, Hivory owns 1.

2015 was the busiest year, with 31 new systems, most of them 4G. Free Mobile switched on the first 5G here in December 2020; Bouygues Telecom followed in December 2020, SFR followed in November 2021. The oldest transmitter still listed here goes back to 2000.

Of the 20 masts in the commune, SFR is the only carrier on 7 masts.

By mast count, Dugny is 24th of the 36 Seine-Saint-Denis towns that have five or more. With 20 masts for 11,700 residents, or 17 per 10,000, it has more masts per inhabitant than the median for those towns (7).

3.5 GHz 5G is declared by SFR on 7 of its 9 masts, Orange on all 6 masts, Bouygues Telecom on 4 of its 6 masts and Free Mobile on 3 of its 5 masts.

Garges-les-Gonesse lies 2.1 km to the north-west and has a higher 5G share (100%).

At 4 km² with 11,700 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Métropole du Grand Paris intercommunal grouping.

14 buildings and 4 pylons and 2 masts carry the commune's antennas.
