3D Location Based on Wireless Time of Flight Calculation
First Claim
1. An indoor location system, comprising:
- (a) a server, said server adapted to calculate a position of a mobile device within a predefined area;
(b) a Master Beacon including;
(i) a first radio communications capability, over which said master beacons is adapted to periodically broadcast advertising packets and to capture scan request packets broadcast from a mobile device,(ii) a second radio communications capability, over which said master beacon is adapted to transmit data packets to said server and receive data packets from said server, and(iii) a master processor, adapted to send data relating to said scan request packets via said second radio communications capability to said server, said data being sent together with a time stamp reflecting a time of receiving said scan request packets; and
(c) a plurality of Slave Beacons, each said slave beacon including;
(i) said first radio communications capability, adapted to capture said advertising packets and said scan request packets, and to transmit data packets,(ii) a slave processor, adapted to send data relating to said scan request packets to said server, said data being sent together with a time stamp reflecting a time of receiving said scan request packets;
said server is adapted to calculate a respective distance of each said beacons from said mobile device.
