Abstract:
A method for determining the speed of a wireless device includes the steps of receiving channel quality indicator data, determining the fast fading characteristics of the received channel quality indicator data, comparing the fast fading characteristics of the received channel quality indicator data against benchmark channel quality indicator data, and determining the speed of the wireless device based on the comparison. The channel quality indicator data is indicative of the signal quality at a wireless device. The benchmark data includes fast fading characteristics.
