Abstract
Methods, devices, and apparatuses are described for wireless communications using a multidimensional algorithm for roaming. In one aspect, an initial set of candidate access points (APs) is produced by a station using a roaming scan. The initial set may be identified based at least in part on an initial metric (e.g., beacon signal strength). A probe signal may be transmitted by the station to at least one of the candidate APs in the initial set and information may be received in response to the probe signals. The station may then identify a reduced set from the initial set based at least in part on the received information, where the reduced set is used to select a target AP. At least one additional metric may be identified and the probe signal may be configured to obtain information corresponding to the additional metrics. This information may be used by the station to select the candidate APs in the reduced set.
