Group Leader's Message
While still there are many discussions on what the next generation mobile networks would look like, it is our belief that it will feature a well-collaborative and harmonized heterogeneous architecture that accommodates all existing and future new advanced mobile technologies. Looking back at the evolution path of the mobile communications in the past two decades, we see a trend in accommodating more enriched services with better spectrum efficiency in the newer system in comparison with their respective predecessors. It is however understood commonly that the previous approach was not successful and no single system can provide global services at acceptable quality to every user at every location. So looking for such a modified system to be called as 4G would be of no hope. Instead, we have to appreciate the variety and number of services and applications that are being created in a regular basis in mobile environment. The ubiquitous mobile communications of the future will need real cooperation (rather than competition) among multiple systems and service providers. New services and applications are being created regularly with different bandwidth, delay, security, and location needs and there would be impossible to provide such global and ubiquitous communications through a single system or a single family of homogeneous systems.

Following this belief, the Wireless Networking Group (WiNG) at the School of Electrical and Information Engineering, University of Sydney pursues advanced research and development for individual networks and their integration toward a collaborated heterogeneous architecture. We work on the architecture design and related protocols and techniques to make the future mobile broadband Internet closer. We also work on securing the information network and bringing both infrastructure-based networks (e.g. cellular mobile, wireless LAN, and WiMax) and infrastructure-less networks (e.g. ad hoc and sensor networks) into a mutual agreement and collaboration. Our research applies into mobile terrestrial and satellite communications.

WiNG realizes the importance of international collaborations and visibility. In that context, we carry out several of our research through international collaborations with academia and industry in Asia, Europe, and North America and we always welcome new partners from overseas.
