Abstract :
A 27.75-29.32 GHz millimetre wave fibre-radio antenna unit is reported which distributes 622 Mbit/s downlink and 40 Mbit/s composite TDMA uplink ATM multimedia signals to/from customer premises equipment (CPE) located within a 500 m range. Coherent optical signals are used to distribute downlink transmit and LO signals. The uplink millimetre wave signal is downconverted to a 615 MHz IF for transmission on an intensity modulated optical link to the central station.
