Classification of base stations in trunked communication systems

Classification of base stations in trunked communication systems

Base station (or base radio station, BS) is – according to the International Telecommunication Union 's (ITU) Radio Regulations (RR) [1] – a " land station in the land mobile service. It provides connectivity between devices to devices or devices to network for network accessibility in all the available devices efficiently. . A central-controlled trunked system uses a control channel (as shown). Frequencies are for discussion purposes and do not correspond to any specific system. A TETRA mobile user can communicate to other users via a base station or directly. . Private trunked mobile radio systems have been operated many years by offices and organisations related to security tasks, airports, the major industry, energy-suppliers, public personal transport operators and taxi-offices. In a local range defined by the base station, voice and data radio is. . 'Trunked' radio systems differ from 'conventional' radio systems in that a conventional radio system uses a dedicated channel (frequency) for each individual group of users, while 'trunking' radio systems use a pool of channels which are available for a great many different groups of users.
