Abstract

Aspects receive different instances of reception data from different respective wireless communication receivers that include broadcast data packets broadcast from a mobile device, geographic locations of the communication receivers and times of reception of the broadcast data packet by the respective receivers. Each broadcast data packet includes a time of broadcast by the mobile device and a unique identifier of the mobile device. Aspects determine a geographic location of the mobile device at the time of broadcast of the data packets as a function of triangulating to the geographic locations of the different communication receivers; and/or of determining a Doppler shift in frequency transmission data of an instance of reception of a first data packet relative to frequency transmission data of another instance of reception of another, second data packet transmission broadcast at a different time than the first data packet.
