UMTS network simulation in Opnet Modeler environment and real network operation
 Kuchár, Peter ; Molnár, Karol (referee) ; Novotný, Vít (advisor)
This bachelor thesis is devoted to mobile networks and specially to UMTS. First part contains theoretical information about mobile networks, history and present of mobile communication. It continues with comparasion between Node-B specification in the Opnet Modeler 14.5 and real node by 3GPP international community. Second part describes works on simulation and results of measured parameters. Simulation is focused on sensitive services like a VoIP or video. In simulation voice service is used VoIP and few data services running in background. Measurement in real network was executed in several networks which belong to different providers and supports different techniques. In real networks IxChariot was used. IxChariot is the industry’s leading test tool to predict device and system performance under realistic load conditions. Real network results and results from Opnet Modeler 14.5 simulation are practically equal. Aplication of Hamachi in real network did not have influence on the results measured.
