2 supports are declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

2 underground or tunnel sites and 4 buildings carry the commune's antennas.

Antennas are listed at Métro Serge_gainsbourg_l11, Metro Mairie des Lilas L11, 94-96-102 rue Romain Rolland, 47-51 Bvd Eugenes Decros and 27 rue de Villegranges.

ANFR has approved 3 new sites that are not live yet, plus additions on 2 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 171 Rue de Paris, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 37 Avenue Maréchal Juin and SFR (4G and 5G, including 5G at 3.5 GHz) at 57 Rue du Garde Chasse. 4 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The tallest structure is a 56 m building at 47-51 Bvd Eugenes Decros. The median is 35 m, above the Seine-Saint-Denis median of 25 m.

Systems from 1996 are still on the register. Local 5G started with Bouygues Telecom in November 2020; SFR followed in July 2021, Orange followed in May 2023. 2014 was the busiest year, with 12 new systems, most of them 3G.

2 masts carry all four networks.

Among the 36 Seine-Saint-Denis towns with at least five masts, Les Lilas ranks 36th by mast count. With 6 masts for 23,843 residents, or 3 per 10,000, it has fewer masts per inhabitant than the median for those towns (7).

On 3.5 GHz, the fastest 5G band: Orange on 4 of its 5 masts, Bouygues Telecom on 2 of its 4 masts, SFR on 2 of its 3 masts and Free Mobile on 1 of its 2 masts.

1.2 km to the north-east, neighbouring Romainville has 18 masts, more than here.

At 1 km² with 23,843 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.
