A WIFI-enabled and GPS-enabled user device executes a hotspot location utility, which enables the device to detect WIFI hotspots and update a locally-stored hotspot location database (LHLD) containing geographically-mapped hotspots. When a hotspot is detected, the device accesses the hotspot, retrieves identification information and usage terms from the hotspot, and measures performance metrics of the hotspot. The utility stores the identified hotspot with the current GPS coordinate as an entry within the LHLD. When a user later desires to locate hotspots within a particular geographic location, the user enters the physical address of the location, and hotspots with matching (or proximate) GPS coordinates of the entered address are presented to the user. The user may specify certain preferences for usage terms, performance metrics, and location criteria, and the utility filters all geographic hits and returns only hotspots in the geographic location that also satisfy these preferences.
