A rapidly growing demand for fast wireless services calls for wideband communication systems with wideband antennas, which are compact, aesthetically appealing and inexpensive, yet have good performance. With novel concepts, this project aims to produce a new class of antennas that deliver impressive performance (bandwidth and gain) while taking up a dramatically reduced area in a way that was impossible before, increasing a figure-of-merit to up to seven times the state-of-the-art. Their planar geometry and simplicity lead to low cost. This is expected to create new knowledge, design methods and examples, prototypes, test results and guidelines required to design, optimise and make these versatile antennas for emerging robust broadband wireless systems.Read moreRead less
Physical layer security techniques for multiuser wireless networks. This project will develop innovative new security techniques for wireless networks. The novel techniques we develop will exploit the natural variability of wireless communication channels in order to deliver much-enhanced data security to a whole range of applications over the mobile internet.
Dual-band antennas with digitally steerable beams made out of multi-state electromagnetic elements. A collection of antennas required for forthcoming wireless systems will be designed, made and tested. They are ideal for wireless on-body medical devices and wireless transmission of high-quality video and high-speed data. These systems will bring great benefits to wireless users and patients, including better quality of life and convenience.
Coordinated non-coherent wireless for safe and secure networking. Distributed wireless networks have the potential to serve simultaneous users streaming high-definition video, no dead zones, no interference among users and no reduction in data rate as more users are added. This project will provide a solution to the current limitations of distributed wireless networks aiming at user safety and privacy.
Optimum cross-layer design in wireless communication systems with channel uncertainty. For wireless communications to be part of Australia's information delivery infrastructure, including the National Broadband Network, requires improvements in reliability, speed and cost effectiveness over current technologies. The assembled world class research team has the objective to develop advanced design techniques to meet this challenge.

What to do about WiFi Congestion? New methods for dense, wireless networks. This project aims to design and analyse new protocols for (wireless) WiFi networks. The demand on current WiFi networks is escalating at a tremendous rate. WiFi uses the unlicensed radio spectrum, so innovation can occur more easily over WiFi than over carrier-owned networks.

New methods for dense, wireless networks. This project aims to design and analyse new protocols for (wireless) WiFi networks. The demand on current WiFi networks is escalating at a tremendous rate. WiFi uses the unlicensed radio spectrum, so innovation can occur more easily over WiFi than over carrier-owned networks. WiFi also provides data offloading from severely congested cellular wireless networks. Unfortunately, the current WiFi multiple access protocols were not designed to handle closely packed WiFi networks and the resulting interference. This project takes a novel approach to develop algorithms that are much more robust to interference, and which use simple, distributed mechanisms to feed channel state information back from the receiver to the transmitter to maximise performance.Read moreRead less
