<p>A wireless communication system and method are provided, where a base station communication device (203) includes a carrier wave-based transmitter (207) and an ultrawideband receiver (208). A mobile communication device (220) includes a carrier wave-based receiver (223) and an ultrawideband transmitter (228). Carrier wave communications are carried out in a forward channel from the base station communication device (203) to the mobile communication device (220), and ultrawideband communications are carried out in a reverse channel from the mobile communication device (220) to the base station communication device (203). As a result, the power requirements of the mobile communication device (220) are significantly reduced.</p> |
