Cleveland is an area in the north east of England.
Historically Cleveland, part of the North Riding of Yorkshire, was located entirely to the south of the River Tees and its largest town was Guisborough.
A non-metropolitan county of Cleveland was created in 1974 under the Local Government Act 1972, named after the historic region but not covering it all, and also including land north of the River Tees in County Durham. It was based around the Teesside urban area and included Middlesbrough, Stockton-on-Tees, Hartlepool and Redcar. At this time the use of the name �Cleveland� or �Teesside� to refer to the area was virtually interchangeable. The county was abolished in 1996 with its boroughs becoming unitary authorities and the Tees re-established as the border between North Yorkshire and County Durham for ceremonial purposes only.
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.
