Abstract
A method of estimation of a location of a terminal within an area of coverage of a wireless network comprising at least one fixed node. The method comprises estimating the location of the terminal on the basis of at least a comparison between data representing a first metric of a complex frequency response of a radio channel between the terminal and one of the at least one fixed node and data representing a plurality of stored metrics. Each of the plurality of stored metrics being related to one of a plurality of different locations within the network and each stored metric being of a complex frequency response measured between the one of the fixed nodes and the location within the network to which the metric relates.
