- The Voice-Over Internet Protocol (VoIP) technology allows the voice information and the video traffic to passover the IP network using the existing infrastructure. WiMAX (Worldwide interoperability for micro wave accesstechnology) is a technology based on IEEE 802.16 standard, which provides broadband service for fixed and mobile usersover long distances at high speed. Modulation and coding is one of the features of PHY layer which is used to load the datain the uplink and downlink during transmission. The existing system selects the MCS based on the channelquality.Modulation and coding scheme can also be selected based on the type of traffic used. This paper focuses on thephysical layer design aspect namely modulation and coding scheme(MCS) for the VOIP traffic over WiMAX. Thesimulation is done for fixed WiMAX environment. Throughput and packet delay is taken as the main parameter forevaluating the performance of WiMAX. This paper focuses on selecting appropriate Modulation and encoding scheme overthe WiMAX network for the voice and video application.
