Optical-OFDM provides Australia with an opportunity to develop a new, high-tech, easy-to-export technology with a very large market potential spanning three key communications markets: wireless personal-area networks, local-area networks and long-haul (80-4000 km) optical networks. It is based on innovative Australian technology generated from two research strengths: photonics and OFDM. OFDM is already the basis of most non-optical broadband systems, including digital broadcasting and ADSL. Patent applications have been filed. One application enables bandwidths to rural and remote communities to be quadrupled without laying new cables. By launching off this local market Australian industry can develop a world leading industry.Read moreRead less

Reliable, flexible broadband delivery is critical for Australian business and for the Australian community. This project will develop the technology on which a new generation of optical wireless communication systems will be based. By using optical rather than radio frequencies they will combine the data rates of optical with the mobility of wireless. They will fill many of the gaps in existing broadband delivery including providing a new flexible last-mile technology and an alternative form of local area network for indoor use. They will lead to new business opportunities within Australia and provide excellent research training in the field of OFDM, a field in which there is significant local R&D in Australian and multinational companies.Read moreRead less
Reconfigurable Conformal Antenna Arrays for Broadband in the Sky Networks. The project aims to develop the theory and technology for a novel type of antennas, namely, reconfigurable conformal antenna arrays, for future broadband in the sky networks (BISNets). BISNets are essential to providing digital services to users on the move and in remote areas.

The project aims to develop the theory and technology for a novel type of antennas, namely, reconfigurable conformal antenna arrays, for future broadband in the sky networks (BISNets). BISNets are essential to providing digital services to users on the move and in remote areas. The antenna would be conformal to the surface of the mounting platform, and its elements would be reconfigured in situ to generate the optimum radiation characteristics to suit the radio environment. It is expected that the project would advance the scientific knowledge of space-borne wireless communications and sensing in general, and antennas in particular, and significantly enhance the performance and reduce the cost of BISNets.Read moreRead less

User-based Radio Spectrum Harvesting System. Demand on wireless traffic is estimated to increase more than one thousand-fold in the next 10 years. As existing networks are quickly becoming overloaded, this project aims to improve radio spectrum utilisation by harvesting temporarily unused spectrum holes to accommodate future traffic.

Demand on wireless traffic is estimated to increase more than one thousand-fold in the next 10 years. As existing networks are quickly becoming overloaded, this project aims to improve radio spectrum utilisation by harvesting temporarily unused spectrum holes to accommodate future traffic. The proposed spectrum harvesting system is cost-effective as it will rely on a software that runs on users' devices to sense and report spectrum holes to mobile service providers. An unprecedented communications framework that incentivises both users and service providers to harvest and trade/share radio spectrum holes will be developed. It will reduce the costs of the radio spectrum, allowing cheaper and better mobile data services for the Australian public.Read moreRead less
Efficient cross-layer coding techniques for wireless networks. This project is proposed to develop novel wireless communication/networking design theory and practical strategies based on the emerging network coding technique. The expected outcomes can be used to substantially increase network throughput and reliability of future wireless services, such as wireless Internet and mobile broadcasting.
Optimisation of base station beamforming for wireless broadband internet services in rural areas. The NBN aims to deliver 100 Mbps to Australians in major cities but much lower speeds to rural areas. A key outcome of the project is a sound foundation for the design of antenna arrays and beamformers to enable cost effective and efficient wireless internet services for rural areas and meet a challenge of national importance.
