Abstract
Systems, devices, and methods for communications among access points (APs) and mobile wireless devices are disclosed. A database having a persistent profile table (PPT) can be used to store information related to access point operations. Information related to a plurality of APs can be detected and stored in the PPT. Certain information may be common to multiple of the APs, allowing for compression of the data for more efficient storage. Fingerprint data related to the APs can be clustered based on a first order identifier (e.g., SSID, PLMN) and a second order identifier (e.g., MAC, MAC prefix, cell ID). The clusters can be further compressed by, for example, storing common features only once, and storing uncommon features individually, along with an identifier frame indicating which features are unique within the group of clusters. A mobile device can query the persistent profile table to verify the identity of unknown APs.
