1. A method comprising:
for a first wireless device associated with a current location, obtaining at least one parameter of a first wireless signal received by the first wireless device at the current location from a first access point (AP) of a plurality of APs;
comparing the at least one parameter of the first wireless signal to at least one parameter of a second wireless signal received by at least one other wireless device at the current location from a second AP of the plurality of APs; and
triggering a roaming operation of the first wireless device from the first AP to the second AP if the comparison satisfies a mobility threshold that varies based on the at least one parameter of the first wireless signal, wherein the mobility threshold corresponds to a varying degree of improvement to trigger the roaming operation of the first wireless device from the first AP to the second AP.
