Title: MULTIPLE WI-FI CHANNEL MAPS FOR DENSE ACCESS POINT ENVIRONMENTS
Abstract:
Methods, systems, and devices are described for wireless communications. A communication device may utilize enhanced roaming techniques to use multiple channel maps for a high density AP environment. For instance, a communication device performs at least a partial channel scan by a communications device while the communications device is connected to an access point (AP) associated with a basic service set identifier (BSSID). The communication device further selects a channel map from a plurality of channel maps associated with the BSSID based at least in part on the partial scan, wherein each of the channel maps associated with the BSSID comprises a different set of signal strength measurements for a same set of neighboring APs. The communication device also uses the selected channel map as a basis for a roaming operation by the wireless device.
