Cell towers in Voreppe (Isère)

Declared supports include 1 silo, with pylons making up most of the remainder.

Declared locations include Les Buissières, Chem des Seites, 551 rue Pommarin, Les Glaires, Le Chevalon and La Rigonniere.

The highest support stands 42 m at Les Glaires (pylon). The median height of measured supports is 28 m.

2019 was the busiest year, with 24 new systems, most of them 4G. Bouygues Telecom switched on the first 5G here in November 2020; Free Mobile followed in December 2020, Orange followed in May 2021. The oldest transmitter still listed here goes back to 1997.

21 systems were switched on in the past 12 months. Approved additions not yet in service are pending on one existing mast, for example Free Mobile (5G 3.5 GHz) at Les Glaires. 11 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3.5 GHz 5G is declared by Bouygues Telecom on 5 of its 6 masts, Orange on all 4 masts, Free Mobile on 3 of its 5 masts and SFR on all 3 masts.

Supports leave a gap of about 2 km to the north-east of the centre.

Nearby, Moirans (7.3 km to the north-west) has only 9 masts.

Of the 13 masts in the commune, only one mast carries all four networks.

By mast count, Voreppe is 9th of the 43 Isère towns that have five or more. With 13 masts for 9,922 residents, or 13 per 10,000, it has more masts per inhabitant than the median for those towns (9).

9,922 residents over 29 km²: supports are mostly pylons, not rooftops. It is part of the CA du Pays Voironnais intercommunal grouping.
