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.

[ What is claimed is:] [12.]12. A method of communicating over a wireless link with a central terminal of a wireless telecommunications system, comprising the steps of:providing 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;converting, within the first signal processing unit, signals between said first frequencies and a second frequency;providing a second signal processing unit 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;forming the second signal processing unit from signal processing circuitry which is independent of the operating frequency band;passing the signals 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; andpassing control signals between the first and second signal processing units over the connection medium at a predetermined frequency distinct from the second frequency, wherein the second frequency comprises a downlink second frequency for signals passed from the first signal processing unit to the second signal processing unit and an uplink second frequency for signals passed from the second signal processing unit to the first signal processing unit.
