Abstract
A wireless communication system and method includes antenna arrays at both the transmitter and receiver having a plurality of elements for very high data rate communication. Phased array antennas or directive fixed beam antennas are used with a beamwidth in azimuth and elevation less than 30° to increase the power margin and to decrease the delay spread of signals at the receiver to permit wireless data communications at high data rates in closed environments, for example, bursty transmissions and isochronous communications. The wireless communication system is capable of data transmission rates which exceed 1 Gbps with propagation losses of up to at least 60 dB relative to one meter.
