Derbyshire is a county in the East Midlands of England. A substantial portion of the Peak District National Park lies within Derbyshire. The northern part of Derbyshire overlaps with the Pennines, a famous chain of hills and mountains.

All wide area and local Police communications are carried out on the UK wide TETRA network called Airwave using a mixture of Motorola, Sepura and EADS radio terminals. This system replaced their previous 150Mhz AM simulcast wide area and local PR UHF systems. Some historic information can be found here: www.dtels.org/html/site_map.htm
Local authority NHS Ambulance services use Airwave, replacing their previous wide area 166Mhz and UHF handheld 'incident' radio systems.
Local authority Fire & Rescue services also use Airwave as their prime method of wide area 'vehicle to control' communications replacing a mixture of FM and AM simulcast systems in the 70Mhz band. At incident Fireground communications are still carried out on simplex UHF frequencies with some cross-band capabilities to Airwave.
Fire & Rescue Services are in the process of migrating to Airwave, some are still operational on 70Mhz.
