Abstract

A device includes a gyrating circuit that generates a motion parameter based on motion of the device. An RF transceiver generates an outbound RF signal from an outbound symbol stream, transmits the outbound RF signal to a remote station of a wireless network, and generates an inbound symbol stream from an inbound RF signal received from the at least one remote station. A processing module processes the motion parameter to produce motion data, converts outbound data into the outbound symbol stream, converts the inbound symbol stream into inbound data, compares current motion data to past motion data, detects when a difference between the current motion data and the past motion data compares unfavorably to a motion change threshold, and include the motion data in the outbound data when the difference between the current motion data and the past motion data compares unfavorably to the motion change threshold.
