Abstract
A network element for a wireless communication system is locatable to couple at least one base station to an antenna array. The network element comprises at least one receiver arranged to receive a radio frequency signal from the at least one base station or the antenna array and modem logic operably coupled to the at least one receiver. The modem logic comprises radio frequency conversion circuitry arranged to down-convert a received radio frequency signal to a baseband signal; analogue-to-digital conversion logic arranged to convert the baseband signal to digitized signals; and beam-form processing logic arranged to perform active beam-forming adjustment on the digitized signals. The modem logic further comprises digital-to-analogue conversion logic arranged to convert the beam-form adjusted digitized signals to analogue signals and radio frequency conversion circuitry arranged to up-convert the analogue signals to a radio frequency radio signal for forwarding to the antenna array or the at least one base station.
