Mobile learning is the ability to obtain or deliver learning materials on personal pocket electronic devices such as mobile phones, PDAs or tablets. Mobile devices support multimedia elements, such as video conferencing and can be accessed by all learners via WiFi/WiMAX network. In this paper, we evaluate the quality of network traffic when video conferencing is being used by number of mobile devices over Wi-Fi/WiMAX network. A network testbed is designed with the E-Learning portal and PRTG is used to monitor the traffic; i.e. web traffic and multimedia traffic. The experimental result shows that the quality of traffic while using video conferencing in mobile learning is dependant on the number of users, accessing time & duration. It also shows that the technologies used are performing at desired level.
