Cell towers in Ay (Marne)

Most of the town's 7 masts are pylons (5); 1 silo make up the rest of the mix.

Declared locations include Les Dix Huits Arpents, La Maladrerie, Entre Deux Voies, Le Cheminet, 1 Espace la Tour and 8 Rue du Vivier.

ANFR lists a 34 m silo at Entre Deux Voies as the tallest structure. The median is 15 m, slightly below the Marne median of 27 m.

2016 was the busiest year, with 9 new systems, most of them 4G. Free Mobile opened 5G here in December 2020; Orange followed in October 2025. The oldest transmitter still listed here goes back to 1998.

8 systems were switched on in the past 12 months. Approved additions not yet in service are pending on 2 existing masts, for example Bouygues Telecom (4G 1800 MHz) at Les Dix Huits Arpents and Free Mobile (5G 700 MHz) at Le Cheminet. 3 Free Mobile 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

3.5 GHz 5G is declared by Free Mobile on 1 of its 3 masts and Orange on its only mast. 57% of the town's masts carry 5G, fewer than across Marne towns with five or more masts (88%).

Of the 7 masts in the commune, Free Mobile is the only carrier on 3 masts.

Epernay lies 3.6 km to the south-west and has 11 masts, more than here.

Supports leave a gap of about 2.2 km to the east of the centre.
