Cell towers in Le Grand-Quevilly

Masts stand at '' Les Hortensias'', 35 Avenue Savorgnan de Brazza, 29 avenue Franklin Roosevelt, Immeuble les Renoncules, 35 Rue du Docteur Laennec and P.a des Bords de Seine.

Over the past 12 months ANFR recorded 8 new systems here. ANFR has approved one new site that is not live yet, plus additions on 9 existing masts. New: SFR (3G 2100 MHz) at rue de l'Industrie. 18 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (26 of 32), so heights stay modest; the tallest support is 58 m at 2 Rue Edwin Aldrin.

3 masts belong to the commune itself and 1 to Totem; the rest sit mainly on private buildings.

Systems from 2000 are still on the register. Bouygues Telecom switched on the first 5G here in November 2020; Free Mobile followed in December 2020, Orange followed in March 2021. 2019 was the busiest year, with 47 new systems, most of them 4G.

Among the 30 Seine-Maritime towns with at least five masts, Le Grand-Quevilly ranks 3rd by mast count. With 32 masts for 25,789 residents, or 12 per 10,000, it has more masts per inhabitant than the median for those towns (8).

On 3.5 GHz, the fastest 5G band: Free Mobile on 10 of its 11 masts, Bouygues Telecom on 5 of its 13 masts, Orange on 5 of its 9 masts and SFR on 4 of its 7 masts.

Nearby, Le Petit-Quevilly (1.8 km to the north-east) has only 19 masts.

9 supports carry only Bouygues Telecom.

At 11 km² with 25,789 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Métropole Rouen Normandie intercommunal grouping.

26 buildings and 5 pylons 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.
