Simulative Investigation of QoS parameters for VoIP over WiMAX networks
WiMAX is a wireless broadband access technology which provides high data rates, long coverage and IP based connectivity to the stationary as well as mobile users. Voice over Internet Protocol (VoIP) through WiMAX is found to be very promising. In this paper, simulative investigations have been done to identify the suitable voice codec for the same. In doing so, silence suppressed voice signal a...
متن کاملPerformance Analysis of VoIP Codecs over WiMAX Networks
Real-time services such as VoIP are becoming popular and are major revenue earners for network service providers. These services no longer confined to the wired domain and extended over wireless networks. Although some of the existing wireless technologies can support some low-band width applications, the bandwidth demands of many multimedia applications exceed the capacity of these technologie...

متن کاملSimulation and Performance Evaluation of WiFi and WiMAX using OPNET
Wireless Fidelity (WiFi) network is based on the IEEE 802.11 standard. Worldwide Interoperability for Microwave Access (WiMAX), based on IEEE 802.16, is a standard with similar principles. The main advantage of WiMAX over WiFi is that it covers larger areas and has higher data rates. WiMAX network operators provide WiMAX subscriber units that enable connection to the metropolitan WiMAX network ...
متن کاملTriple Play Services including Mobile TV, VoIP, and Internet over Mobile WiMAX Networks
Mobile TV, Voice over Internet Protocol (VoIP), and Internet access services are important for mobile users and network service providers. Mobile WiMAX devices can support all three services also known as triple play. In this paper we analyze user capacity of Mobile WiMAX systems for each of these three services. We consider various link characteristics, interference scenarios, modulations, QoS...
