摘要：Mobility management is a leading factor in personal communications services networks. Thus, it is important to verify that the mobile unit receives all services whenever moving from one place to another. This paper deals with the study and analysis of the optimal transmission power at a specific zone through a GSM cellular network. The definition of coverage area is constructed by a proper analysis of signal strength measurement. Some problematic tasks appear through the variation of geographical terrain. An accurate coverage area obtained due to an effective cellular positioning method that not requires any significant changes to the network or mobile device.
