Abstract

A circuit includes a package substrate that supports an on-chip gyrating circuit that generates a motion parameter based on motion of the circuit. The package substrate further supports a die that supports a processing module that processes the motion parameter to produce motion data, wherein the processing module further generates a receive control signal and a transmit control signal in accordance with the motion data. The die further supports a wireless local area network transceiver that generates an outbound RF signal that includes outbound data and that generates voice inbound data from an inbound RF signal, wherein the wireless local area network transceiver is further operable to adjust a receive parameter based on the receive control signal and to adjust a transmit parameter in response to the transmit control signal.
