Abstract:
1. A system for performing a device location procedure, comprising: a plurality of electronic devices that wirelessly transmit device location signals, said plurality of electronic devices including satellites that transmit satellite beacon signals and base stations that transmit pilot signals; a plurality of access points that wirelessly transmit access-point beacon signals; a location detector that coordinates said device location procedure by measuring said device location signals and said access-point beacon signals to determine a current physical location of a mobile device, said location detector generating satellite information by measuring said satellite beacon signals, base station information by measuring said pilot signals, and access point information by measuring said access-point beacon signals, said satellite information, said base station information, and said access point information including signal strength measurements and signal quality measurements, said location detector analyzing said satellite information, said base station information, and said access point information to select an optimal system configuration from certain of said satellites, said base stations, and said access points, said location detector then utilizing said optimal system configuration to determine said current physical location of said mobile device.
