Performance Analysis of VoIP Using WiMAX, LTE and WLAN Mobile Networks

Prijenos govora preko Internet protokola je usluga koja ima sve veću primjenu kod korisnika. Kako je govor usluga koja se odvija u stvarnom vremenu njena kvaliteta je izrazito važna. Kritični parametri kvalitete ove usluge su: kašnjenje, jitter, gubitak paketa i propusnost. Ovisno o vrsti mreže koja se koristi za prijenos govora variraju iznosi ovih parametara odnosno kvaliteta usluge. Analizirani su kritični parametri kvalitete usluge VoIP (jitter, kašnjenje, gubitak paketa) za tri različite mreže: WLAN, LTE i WiMAX, te su utvrđene performanse ove usluge za te mreže.Voice over Internet protocol is a service that has been increasingly used by the user. As speech being a real-time service it's quality is extremely important. Critical parameters of the quality of service are: delay, jitter, packet loss and throughput. Depending on the type of network used for voice transmission the amount of these parameters varies that is the quality of service varies. Critical parameters of quality of service for VoIP (jitter, delay, packet loss) were analyzed in three different networks: WLAN, LTE and WiMAX, and the performance of the service for these networks is determined
