Abstract
A wireless network apparatus includes a receive circuit, a transmit circuit, and a processor. The receive circuit receives a first signal over a wireless link. The first signal represents packets of first data. The transmit circuit transmits a second signal over the wireless link at a power level indicated by a transmit power control signal. The second signal represents packets of second data. The processor determines a link quality of the wireless link based on the first signal. The processor selects one of a plurality of link quality thresholds based on the power level. The processor compares the link quality to the selected one of the plurality of link quality thresholds. The processor generates the transmit power control signal based on the comparison.
