Mainly in the thesis I would like to introduce an examination of positioning methods, which are applicable in the 4th generation cellular networks. The research can be divided three partly independent time slots.

In the first trimester, I had done a literature research and gained new knowledge of radio positioning methods with their applications in mobile networks. This operation affected the main advantages and disadvantages of positioning.

Second trimester examined the techniques of mobile network, in particular the currently latest generation mobile network, focused on their structure, physical parameters. The new generation networks advantages had compared to the previous network techniques.

The third trimester covered up the simulator, which has been developed over the years in MATLAB environment organized by the Department of Networked Systems and Services. It is based on the WINNER II channel model, which achieved by the WINNER team. The simulator proved to be suitable for testing positioning methods of the 4th generation mobile networks. My job focused on the implementation of TOA (Time of Arrival) positioning method inside the simulator. In this slot the first examination part is the accuracy of the method in urban which followed by the suburban, rural settings in multiple base station configuration. In the final section I drew conclusions about the results.
