Performance analysis of VoIP over 3G and 4G LTE network

Wireless mobile telecommunication has evolved from the Third Generation (3G) to Fourth Generation (4G) network. Mobile WiMAX and Long Term Evolution are the first two platforms preferred by Telco's to offer network services for customers for profit making and Voice of Internet Protocol (VOIP). VOIP is an online streaming method to deliver voice communication that applied by organization for conference call or voice operation purposes. This paper presents the comparison analysis on 3G and 4G of VoIP network performance. Standard Quality Management Scale recommended by ITU-T P.862 is used for the measurement analysis. A test bed experiments on voice Skype application is done and data is collected. The traffic is analyzed using Jperf software to display the network performance and measurement which is tested in 30 second per session. Result presents performance of bandwidth availability, jitter performance, latency, VoIP, and current LTE4G analysis versus previous WiMAX 4G. It is identified that an average rating of 4 for both 3G and 4G LTE network. This shows performance of the VoIP is achieved. Three elements which are bandwidth, latency and jitter need to be in a good order to get a good connectivity for both connections.
