Performance evaluation of VoIP and video streaming over Wimax IEEE 802.16d and 802.16e

VoIP and video streaming is one of the cheap and fast communication technology. Both of this technology use the internet network on its transmission. In order to get good performance, it is need an high speed and wide coverage internet network. One of the solution is WiMAX network. This research analyze the performance of VoIP and video streaming over WiMAX network (IEEE 802.16d for fixed-nomadic user and IEEE 802.16e for mobile user). The method is simulation on OPNET Modeler 14.5 software, and using 20 MHz and 10 MHz bandwidth. The parameters measured are jitter, throughput, delay and packet loss. The good performance can be get when using the greater channel bandwidth. Packet loss is better when using IEEE 802.16e. There are 8 users served when using channel bandwidth 10 MHz and 16 users when using channel bandwidth 20 MHz.
