| Abstract [eng] |
This work investigates problem of positioning calculation error in mobile cellular networks and provides means to evaluate the errors in variuos aspects. Evaluation results are presented as generated geographical maps and values. The positioning calculation error evaluation is then used to extract requirements for engineered system. System is engineered in a way that it is cellular technology independand and is not limited by generations or carrier technologies of particular investigated networks. Resulting system allows users to select geographical area and precision of analysis to be carried on positioning calculation error. Radio signal propagation and coverage estimation algorithms are used to interpret input data and GIS data is used together to provide visual interpretation for positioning calculation error. This system is beeing used in real word aplications. At the time the system is used in MSC MPS R5 LBS, MPS112 platforms, also in solution „Bitės tinklo padengimo žemėlapiai“. Solution is universal, it can be used in variuos commercial network planning and LBS platforms. The system is cellular network technology neutral and it will be possible to evaluate future cellular or wireless networks as well. |
