Abstract
A system and method for determining the location of nodes within a network. Beamforming coefficients associated with signals transmitted from a first node to a second node are determined and, based on the beamforming coefficients, direction is determined between the first and second nodes. Distance is determined as a function of direction and the location of the second node is determined as a function of distance and direction.
