Abstract
Techniques are provided to measure how fast a wireless channel is changing between a first wireless communication device (e.g., a wireless base station or access point) and a second wireless device (e.g., a wireless client device) based on signals that the first communication wireless device receives at a plurality of antennas from a second wireless communication device. Techniques are also provided to measure a degree of mobility of the second wireless communication device based on signals received at the first communication wireless device from the second communication wireless device.
