An Experimental Evaluation of AGA Algorithm for RSS Positioning in GSM Networks

摘要

The cellular network ability to locate a Mobile Station (MS) depends on network itself as well as on MS equipment. Generally, it is quite difficult to provide fine MS location without implementation of necessary changes either in network or in MS. These changes depend on implemented positioning method. The fundamental Cell Identification (Cell ID) method does not need any changes, but its accuracy is very poor. On the other hand, time-based methods belong to the most accurate methods, but they require very precise time synchronization, which is not present in the GSM (Global System for Mobile Communications) network. Therefore, modifications resulting from this requirement should be implemented.
