Abstract

Today, satellite communication networks are being integrated into the infrastructure of modern Terrestrial communication networks and becoming popular for the delivery of educational content and data, as well as education-centric services, including information, tele-conferencing, entertainment, or ‘edutainment’ services. With fresh demand for new services and applications, it is becoming essential that wireless network architecture seamlessly interoperate with new and existing technologies, protocols and standards. This paper presents recent work on the use of hybrid wireless network infrastructures for delivering tele-education and e-learning applications to remote communities by combining a variety of satellite, terrestrial and wireless technologies, and provides the results from live scenarios carried out employing various methods of interoperability testing. The analysis of the results examines a number of different issues such as delay, jitter, packet loss, latency, throughput measurement, and bandwidth. By combining satellite and terrestrial (wireless) technologies, full coverage and high capacity can be achieved for true broadband services for delivering educational content. The interoperability among such diverse networks imposes a number of challenges regarding service provision and management.

2. Tele-Education Network Services

There are a number of different software tools with various protocols that are available to use in applications related to tele-education, including audio, video, web conferencing, white board, VOIP, application sharing, application remote control and instant messaging. In the following subsections, different services such as virtual class room, learning content management service, teleconference services and webinar/webcast services are discussed. In this study, we have used mainly two tele-education applications for hybrid network evaluation: Clix and Isabel—both are described in later subsections.
