Performance analysis of VOiP over 3G and 4G network / Mohamad Azrai A.Aziz

The third and fourth generation of mobile telecommunication technology known as 3G and 4G respectively is the evolution of previous wireless technology known as 2G network [3, 14, 17, l]. The upgraded features include high-speed transmission of data, global roaming and advanced multimedia access. In mobile telecommunication, both 2G and 3G network are intentionally design for voice communication rather than data networking. On the other hand, 4G networking are established specifically to cater data transmission rather than voice communication. Therefore, 4G should be able to access the data faster than both 3G and 2G [ 19]. Furthermore, streaming higher resolution video, online gaming and video conference should be able to work astonishingly with 4G network. VoIP (Voice over Internet Protocol) is a voice communication technology that transmit voice packet from one destination to another via internet connectivity. By using IP based technology, VoIP have to convert the analog voice signal produced from the sender into digital packets before it being sent to receiver end [ 6]. In this research, the studies is focusing on the comparison of VoIP performance between 3G and 4G network provide by Celcom mobile operator. All the data collected, are being compared with Standard Quality Management Scale recommended by ITU-T [2]. Jperf Software measurement is being used to collect the performance of VoIP and online Unifi Speed Test [4] website is being used to measure the throughput and bandwidth. Two important elements of QoS are being measure and analyzed, which is jitter and latency. These two elements are commonly contributed to the glitch and breaking communication between both parties.
