Abstract :
This paper deals with quality of service (QoS) for triple play, mainly focused on voice and video. For studying changes in quality parameters at different network utilization, was it necessary to simulate LTE networks. For this purpose, the Matlab was chosen, in which we focused on the throughput. We simulated technology in particular scenarios, we changed the frequency and time division duplex, SNR, while we also simulated the behavior of different channels, such as EPA (Extended Pedestrian A Model), EVA (Extended Vehicular A model), ETU (Extended Typical Urban model) and HST (High Speed Train condition). By simulating different scenarios in Matlab, we obtained the required model of throughput and we could determine how it will affect the quality of triple-play services in LTE.
