Abstract

Wireless position location has received significant attention during the past few years, since it is a key factor to military as well as to commercial applications. Radio frequency (RF) techniques are an attractive alternative to satellite location systems. In this paper, a RF location algorithm is proposed. The algorithm is based on one-to-one mapping of the possible positions of the mobile station to vectors of the signal strength space. Simulation results are extracted and the performance of the algorithm is discussed. A position location system has been implemented for indoor environments and statistical measurements results are presented.
