ANFR has approved one new site that is not live yet, plus additions on 2 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 41 Bis Rue du Mûrier. 6 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

The highest support stands 57 m at Le Charentais (pylon). The median is 29 m, slightly below the Indre-et-Loire median of 33 m.

2013 was the busiest year, with 12 new systems, most of them 4G. Free Mobile switched on the first 5G here in December 2020; SFR followed in December 2020, Bouygues Telecom followed in April 2021. The oldest transmitter still listed here goes back to 1996.

By mast count, Saint-Cyr-sur-Loire is 19th of the 30 Indre-et-Loire towns that have five or more. With 6 masts for 17,029 residents, or 4 per 10,000, it has fewer masts per inhabitant than the median for those towns (11).

3.5 GHz 5G is declared by Orange on 3 of its 4 masts, Bouygues Telecom on 2 of its 4 masts, SFR on all 2 masts and Free Mobile on 1 of its 2 masts.

1.2 km to the south, neighbouring La Riche has 9 masts, more than here.

Of the 6 masts in the commune, only one mast carries all four networks.

Supports split between 3 buildings and 3 pylons.
