“…The aim of their work was to analyse the quality of service (QoS) on long distance data transfer between two locations with VoIP over WiMAX. Authors in [1]- [9] analysed the performance of VoIP over mobile WiMAX over Best Effort class in order to identify the best codec. Authors in [5] compared three voice codecs i.e.G.711, G.723 and G.729 were simulated in order to find the most appropriate voice codec for VoIP over WiMAX network under different traffic distributions.…”

WiMAX (Worldwide Interoperability for Microwave Access) is currently one of the hottest technologies in broadband wireless access. The IEEE 802.16 wireless technology provides high throughput broadband connections over long distance. One of killer applications for the 802.16 is Voice over IP (VoIP) service; Voice over Internet Protocol (VoIP) is a vastly growing technology which enables the transport of voice data over Internet Protocol based networks. In this research paper we investigate the performance of VoIP traffic over WiMAX network. We analyzed the performance of VoIP codec G.711 in terms of jitter, delay & throughput by comparing different modes of efficiency. The simulation was done using OPNET Modeler 14.5 and simulation results found the efficiency mode in which VoIP codec performed better. I.

“…The current WiMAX and WiFi wireless networks offer flexibility for supporting real-time applications like VoIP [3]. Also, the technology of IEEE 802.11 (WiFi) is beneficial as low-cost wireless Internet access, whereas IEEE802.16 (Wi-MAX) is providing high data rates (up to 75 Mbps) and a large coverage area (about 50 km) utilizing radio links [4].…”

Worldwide interoperability microwave access (WiMAX) is an 802.16 wireless standard that delivers high speed, provides a data rate of 100 Mbps and a coverage area of 50 km. Voice over internet protocol (VoIP) is flexible and offers low-cost telephony for clients over IP. However, there are still many challenges that must be addressed to provide a stable and good quality voice connection over the internet. The performance of various parameters such as multipath channel model and bandwidth over the Star trajectoryWiMAX network were evaluated under a scenario consisting of four cells. Each cell contains one mobile and one base station. Network performance metrics such as throughput and MOS were used to evaluate the best performance of VoIP codecs. Performance was analyzed via OPNET program14.5. The result use of multipath channel model (disable) was better than using the model (ITU pedestrian A). The value of the throughput at 15 dB was approximately 1600 packet/sec, and at -1 dB was its value 1300 packet/se. According to data, the Multipath channel model of the disable type the value of the MOS was better than the ITU Pedestrian A type.
