DCAN 14: Siting and Design of Radio Telecommunication Equipment
Tetra and Paper Systems
2.12 Another mobile telecommunications system currently in use is Terrestrial Trunked Radio Access (TETRA) which is a standard for digital trunked radio. Presently Northern Ireland does not have any commercial TETRA systems in operation. The Police Service of Northern Ireland operates a system in conjunction with the Northern Ireland Fire Brigade and the Northern Ireland Ambulance Service . There are no plans to allow any commercial use, however some other statutory service providers such as Northern Ireland Electricity may have limited access available in the future. There are also a number of pager systems in operation.
2.13 TETRA and Pager systems can use a variety of antennas, ranging from 1.5m to 6m in length, which can be sited upon existing or new masts.
