Abstract
A circuit includes an on-chip gyrating circuit that generates a motion parameter based on motion of the circuit. A global positioning system (GPS) receiver receives a GPS signal and that generates GPS position data based on the GPS signal. A processing module processes the motion parameter to produce motion data, generates position information based on at least one of the GPS position data and the motion data, converts outbound data into an outbound symbol stream, and converts an inbound symbol stream into inbound data. A wireless local area network (WLAN) transceiver section generates an outbound RF signal from the outbound symbol stream, and converts an inbound RF signal into the inbound symbol stream.
