Abstract
One aspect is a network system including a network sewer and a plurality of gateway hosts coupled to the network server and each including a sectorized antenna and defining a plurality of gateway areas. An overlapping gateway grid includes the plurality gateway areas, each gateway area including sectors. The network system includes a plurality of endpoints, each sending and receiving 10 communication signals to and from at least two gateway hosts, and each comprising an oscillator calibrated with a clocking frequency. The network server determines the location of a target endpoint by sending communication signals between two selected sectorized antennas and the target endpoint to determine one sector from each of the two selected sectorized antennas in which the target endpoint is located, 15 and by calculating the time-of-flight for the communication signal to travel between each of the selected sectorized antennas and the target endpoint.
