Along with a vision that foresees the Fourth Generation of Mobile Communication Systems (4G) as based on a cellular extended short-range network, in this paper we propose a GPS-free localization system, named the Synergic Localization System (SLS), and its localization algorithm. Basically, the cellular network supervises the formation of clusters, where each Mobile Station (MS) can measure its relative distance from the other MS members using its short-range technology. These information are transmitted to the cellular network and used in the localization algorithm by the location server, in addition to the information retrieved using a hybrid Time Of Arrival/Angle Of Arrival (TOA/AOA) technique, to obtain the position of each user in the group. As a consequence of this synergy between cellular and short-range, the fist simulation campaign shows the effectiveness of the SLS in terms of an enhanced accuracy of the estimated positions respect to the actual stand-alone cellular and GPS-based solutions.
