Abstract
Method for estimating position information of base stations as well as terminals for three dimensional centralized real-time spectrum management to achieve high spectral efficiency. In one aspect of the invention, the method comprises i) understanding the position information of plurality of base stations, wherein the plurality of terminals and the base stations form a wireless network, ii) determining, at the central controller, position of a terminal via plurality of communication wirelessly between the base stations and a terminal and between the base station and the central controller, iii) applying network wide real time knowledge at the central controller to electronically steerable antennas to use a resource in a different direction then where it is used by other base stations to achieve frequency reuse of one.
