Cellular geolocation employing hybrid of relative signal strength and propagation delay

Applications for the user's geolocation of wireless services continues to grow. Developing an effective technique for finding geolocation in wireless cellular networks is imperative. This paper presents a hybrid positioning technique to the user's geolocation. The technique is based on combining the propagation delay with relative signal strength. In our study, the propagation delay involves the absolute and simulated delays that played a leading role in the geolocation decision algorithms. The relative signal strength, on the other hand, is the received signal strength differences measured at the user from a number of the neighboring base transceiver stations. By collecting the results from the field trials carried out in a commercial wireless cellular network, it is evident that the proposed technique is able to estimate the user's geolocation with better accuracy and thereby enable location-based services and applications in wireless cellular networks
