A prototype craft that will fly network telecoms starts trials with north Wales mountain rescue services next year

Drones circling above the peaks of Snowdonia, providing an airborne mobile network in remote areas, may soon become a feature of the region’s mountain rescue operation.

The drones – like small unmanned gliders but with twin engines – would carry equipment providing 4G and 5G connectivity that would link mountain rescue teams and other emergency services with people stranded, lost or injured in remote hills where the mobile phone signal is often patchy or nonexistent.
