DCAN 14: Siting and Design of Radio Telecommunication Equipment
Fixed Radio Access (or Fixed Wireless Access)

2.15 Fixed Radio Access (FRA) systems use radio to connect the antennas on a users building and a telecommunications network. FRA provides a fixed telephone service that offers users fast Internet access by radio links instead of a conventional telephone line. It can deliver very high data rates and has the potential to transport a complete range of electronic traffic including telephony, high-speed data, television and multimedia services.
2.16 FRA base stations normally consist of a number of small antennas (usually between 50 and 75 cm in length) that can be located on masts or buildings and other structures. When base stations are placed on buildings or other structures they appear as a collection of mountings each with two small antennas attached. The masts are generally larger than mobile operators’ masts to allow adequate support for the greater number of antennas and their greater wind loading. The antennas attached to customers’ buildings are usually quite small and discreet. Due to the relatively low power of these systems, base stations have to be within about 1km of the consumer with direct line of sight free from obstructions such as hills, buildings, trees or large moving objects and hence there is less flexibility in the choice of location than for mobile services. Further information on factors affecting radio signals is available from Annex C.
2.17 There is currently one operator of a FRA system in Northern Ireland. An experimental system is in operation in Londonderry sponsored by the Department of Enterprise, Trade and Investment.
