Cell towers in Font-Romeu-Odeillo-Via

Masts stand at Serrat de l'Os, Les Boigues, Roc de la Calma, 9 Rue des Narcisses and Serra Dels Fornells.

On 3.5 GHz, the fastest 5G band: Orange on 3 of its 5 masts and Free Mobile on all 2 masts.

Systems from 1998 are still on the register. Free Mobile opened 5G here in January 2022; Orange followed in December 2022, SFR followed in December 2024. 2017 was the busiest year, with 14 new systems, most of them 4G.

Approved additions not yet in service are pending on 3 existing masts, for example Free Mobile (4G and 5G) at Roc de la Calma, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at Les Boigues and Orange (5G, including 5G at 3.5 GHz) at Serrat de l'Os. 1 Bouygues Telecom 5G transmitter is listed as technically operational — installed, but not yet declared commercially in service.

ANFR lists a 31 m pylon at 9 Rue des Narcisses as the tallest structure. The median height of measured supports is 24 m.

4 supports carry only Orange.

Among the 18 Pyrénées-Orientales towns with at least five masts, Font-Romeu-Odeillo-Via ranks 7th by mast count.

Ax-les-Thermes lies 29 km to the north-west and has less 5G (75%).

The widest declared gap between neighbouring supports is about 1.8 km, to the south of the centre.

1,762 residents over 30 km²: supports are mostly pylons, not rooftops.

Supports split between 7 pylons and 1 building.

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