Abstract

A wireless transceiver includes an antenna array that transmits an outbound RF signal containing outbound data to remote transceivers and that receives an inbound RF signal containing inbound data from the remote RF transceivers, wherein the antenna array is configurable based on a control signal. An antenna configuration controller generates the control signal to configure the antenna array to hop among a plurality of radiation patterns based on a hopping sequence. An RF transceiver section generates the outbound RF signal based on the outbound data and that generates the inbound data based on the inbound RF signal. In one configuration, a switching section selectively couples a selected one of the antennas in the array to the RF transceiver section, based on the control signal. In another configuration, the RF transceiver section includes an RF section for each antenna in the array.
