Abstract
The present invention provides a subscriber terminal for communicating over a wireless link with a central terminal of a wireless telecommunications system, the subscriber terminal comprising a first signal processing unit associated with an antenna to transmit and receive signals over the wireless link at first frequencies within an operating frequency band. The first signal processing unit comprises a frequency converter for converting signals between said first frequencies and a second frequency. Further, a second signal processing unit is provided remote from the first signal processing unit and associated with an item of telecommunications equipment to pass signals between said item of telecommunications equipment and the first signal processing unit. The second signal processing unit is formed from signal processing circuitry which is independent of the operating frequency band, the signals being passed between the first signal processing unit and the second signal processing unit at the second frequency via a connection medium connecting the first and second signal processing units. Given this approach, the second signal processing unit can then be formed from signal processing circuitry which is independent of the operating frequency band.
