First Claim
Patent Images
1. A system for determining location information of a plurality of mobile devices comprising:
- a plurality of stationary antennas configured to broadcast information indicative of the antennas location;
a first mobile device configured receive the information indicative of the antennas location and to determine a location of the first mobile device;
wherein the first mobile device is further configured to broadcast information indicative of the location of the first mobile device directly to a second mobile device;
a second mobile device configured to receive the information indicative of the location of the first mobile device directly from the first mobile device and to determine a location of the second mobile device based in part on the information indicative of the location of the first mobile device.
