Abstract: A Wireless Local Area Network (WLAN) system in which wireless terminals each operate upon battery power. One of the wireless terminals acts as a Master to coordinate the transmission and receptions of the Slaves so as to reduce the power consumed by all of the devices. The Slaves operate according to a power up and power down sequence to conserve battery power. Further, the terminals may alternate between being Slaves and being the Master to equalize battery consumption of the wireless terminals.

Abstract: A wireless transceiver includes a phased array of antennas, that transmit 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 phased array of antennas is configurable based on a control signal. An antenna configuration controller generates the control signal to configure the phased array of antennas 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 antenna of the phased array of antennas to the RF transceiver section, based on the control signal. In another configuration, the RF transceiver section includes an RF section for each antenna of the phased array of antennas.

Abstract: An adaptive communication device includes a transceiver that communicates with a first remote communication device in a millimeter wave frequency band in accordance with a first protocol. The transceiver generates conflict detection signals based on signals received from a second remote communication device that communicates in accordance with a second protocol. A conflict detection module detects communication by the second communication device based on the conflict detection signals and generates a model trigger signal in response thereto. A conflict modeling module responds to the model trigger signal by generating idle prediction data based on the conflict detection signals, wherein the idle prediction data predicts an idle period in the communications by the second remote communication device. A transmission control module generates transmit control signals based on the idle prediction data, wherein the transceiver times transmissions sent to the first remote communication device based on the transmit control signals.
