ABSTRACT:
The present invention is directed to systems and methods which monitor a network environment, collect client information available online, and refine location determinations of individual clients based on observed information as well as online information. More particularly, the present invention is directed to systems and methods which monitor the wireless network, collect online receive signal strength indicator (RSSI) information observations from client users, without requiring knowledge of those clients' locations. The present invention is additionally directed to systems and methods to enhance the accuracy of the location determinations in a network, based on observed client information such as, for example, signal strength references.
