1 support is declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

Most of the town's 18 masts are buildings (16); 1 underground or tunnel site make up the rest of the mix.

Declared locations include 3 Rue Youri Gagarine, Metro_ Place Carnot_l11, Allée Victor Grissom, 144 rue de la Republique, Fort de Noisy and rue des Chantaloups.

10 systems were switched on in the past 12 months. ANFR has approved one new site that is not live yet, plus additions on 3 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 2 Passage Voltaire. 13 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

16 of the 18 masts are rooftop-mounted. The tallest support is 59 m at 2 Rue Youri Gagarine (building). The median is 34 m, above the Seine-Saint-Denis median of 25 m.

2020 was the busiest year, with 30 new systems, most of them 5G. Bouygues Telecom switched on the first 5G here in November 2020; SFR followed in December 2020, Free Mobile followed in December 2020. The oldest transmitter still listed here goes back to 1994.

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

Les Lilas lies 1.2 km to the south-west and has only 6 masts.

Of the 18 masts in the commune, only one mast carries all four networks.

By mast count, Romainville is 28th of the 36 Seine-Saint-Denis towns that have five or more. With 18 masts for 37,152 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (7).

At 3 km² with 37,152 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.
