Examine the Accuracy of VOIP Signal Quality over Wireless Channels

The Aim of this paper is to give a basic introduction on VOIP and describe QOS problems. To get the best quality in real time. To investigate the performance of speech over VoIP using commercial 3G wireless network.More specifically, an investigation of IP-based voice communication with emphasis on the effects of a wireless channel and its conditions on the quality of the received speech will be investigated. Simulation will be implemented using Matlab software, and the experiments will be conducted on commercial VoIP networks. The attention is focused on the quality of service in wireless network.
