    • 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.

In an acquisition mode during establishment of the downlink communication path, the downlink signal (212) is transmitted at a high power level and a low transmit rate with the receiver (202) operating at the low transmit rate. In a standby mode after establishment of the downlink communication path, the downlink signal (212) is transmitted at a low power level and a low transmit rate with the receiver (202) operating at the low transmit rate. In a traffic mode upon a request for wireless communication transmission, the downlink signal (212) is transmitted at a high power level and a high transmit rate with the receiver (202) adjusting to operate at the high transmit rate. Upon completion of the wireless communication transmission, the wireless telecommunications system (1) returns to the standby mode and the receiver (202) adjusts to operate at the low transmit rate.

The wireless feeder network comprises a plurality of feeder base stations coupled to the communications network and a plurality of feeder terminals coupled to associated access base stations. Each feeder terminal has a feeder link with a feeder base station, and the feeder links are established over a wireless resource comprising a plurality of resource blocks. Sounding data obtained from the wireless feeder network is used to compute an initial global schedule to allocate to each feeder link at least one resource block, and the global schedule is distributed whereafter the wireless feeder network operates in accordance with the currently distributed global schedule to pass traffic between the communications network and the access base stations. Using traffic reports received during use, an evolutionary algorithm is applied to modify the global schedule, with the resultant updated global schedule then being distributed for use. This enables the allocation of resource blocks to individual feeder links to be varied over time taking account of traffic within the wireless feeder network, thereby improving spectral efficiency.
