Assisted GPS and Advanced Positioning For Emergency Services. Many volunteers have lost their lives fighting bushfires in Australia. Fires are becoming more numerous and more fierce. Some of those firemen could have been saved if better information was available: where they were, where the firefront was and how it was progressing. This project aims to save lives by solving part of this problem: locating and reporting the position of the remote firefighter by making GPS work reliably under trees. ....Assisted GPS and Advanced Positioning For Emergency Services. Many volunteers have lost their lives fighting bushfires in Australia. Fires are becoming more numerous and more fierce. Some of those firemen could have been saved if better information was available: where they were, where the firefront was and how it was progressing. This project aims to save lives by solving part of this problem: locating and reporting the position of the remote firefighter by making GPS work reliably under trees. This will also make search and rescue operations safer and more efficient. The technology can transfer readily into the location-based services market which is set to boom in the next decade. This project helps maintain momentum in Australia's world-class but small positioning industry.Read moreRead less

The aims of the project is to gain better understanding of spatial characteristics of wireless communication channels; and to apply spatial signal processing theory to design receivers for wireless systems. The expected outcomes of the projects are new system theory for spatial signal processing, a new spatial model to characterize wireless communication channels, categorize a relationship between scattering environment antenna spacing and multi-element antenna system capacity, and novel use of multiple antennas to improve the performance of wireless systems. Success in this investigation could have wide applications in the development of future mobile and fixed wireless communication systems.Read moreRead less
VHF wireless technologies for last-mile Internet access in regional Australia. One of Australia's most vexing social issues is the provision of the last-mile Internet connection in regional Australia. The BushLAN team will solve this problem at minimal cost by developing a cellular wireless local area network operating on the TV band I channels (45-70 MHz). We will do this by developing a wireless modem whose design takes into account the properties of radio propagation in the Australian enviro ....VHF wireless technologies for last-mile Internet access in regional Australia.

A possibility to form tree-dimensional 10Tb-density optical memory based on permanent modification, or damage, of transparent dielectrics, using powerful femtosecond laser pulses has already been demonstrated by the Applicants. This project aims to improve the fundamental understanding of ultrafast laser formation of nano-bits using unique ability of photorefractive materials to reversible change and the refractive index. We aim to find ways for controlling the storage time, density and the writing-reading-erasing rate without inducing damage in the material. The results will be applied to efficient formation of high-speed, high density, write-read-erase 3D optical memory for applications in the information technology.
