PASSIVE WIRELESS TRANSMITTER AUTHENTICATION USED FOR RECEIVER LOCATION DETERMINATION

摘要

A client device includes an application to request a client device location, and a receiver to receive a signal from a transmitter. The receiver extracts a transmitter identifier (ID) and a wave propagation parameter (WPP) from the signal. A validator validates the extracted transmitter ID based on comparisons of the extracted ID against a list of pre-assigned transmitter IDs. A location calculator computes the client device location based at least in part on the extracted WPP and provides the computed client device location to the application, if the transmitter ID is validated by the validator.

1. A system to compute device location information, comprising:
a client device including a receiver to receive a signal from a transmitter and to extract a transmitter identifier (ID) and a wave propagation parameter (WPP) from the signal; a validator to validate the transmitter ID based on a list of pre-assigned transmitter IDs; and a location calculator to compute client device location information based at least in part on the extracted WPP, if the transmitter ID is validated by the validator.
