Cell towers in Joinville-le-Pont (Val-de-Marne)

Masts stand at 15 avenue du Président Wilson, Autoroute A4, 36_38 Boulevard du Maréchal Leclerc, 1-3 allée Louis Jouvet, 9 Rue Henri Barbusse and 4 Rue Louis Jouvet.

ANFR has approved one new site that is not live yet, plus additions on one existing mast. New: Bouygues Telecom (4G and 5G) at 39 rue du 42e de Ligne. 4 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Systems from 1998 are still on the register. Bouygues Telecom switched on the first 5G here in November 2020; SFR followed in December 2020, Free Mobile followed in December 2020. 2019 was the busiest year, with 17 new systems, most of them 4G.

On 3.5 GHz, the fastest 5G band: Free Mobile on 4 of its 5 masts, SFR on all 4 masts, Bouygues Telecom on all 2 masts and Orange on all 2 masts. 5G is on 100% of masts here, against 84% across Val-de-Marne towns with five or more masts.

Most antennas sit on rooftops (9 of 10), so heights stay modest; the tallest support is 47 m at 9 Rue Henri Barbusse.

Only one mast carries all four networks; 4 supports carry only Free Mobile.

Nearby, Nogent-sur-Marne (1.4 km to the north-east) has 23 masts, more than here.

Among the 44 Val-de-Marne towns with at least five masts, Joinville-le-Pont ranks 36th by mast count. With 10 masts for 20,525 residents, or 5 per 10,000, it has fewer masts per inhabitant than the median for those towns (7).

At 2 km² with 20,525 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.

9 buildings and 1 mast carry the commune's antennas.

Figures above cover installations declared to ANFR as in service or technically operational, as of October 2026; approved projects are not counted.
