Wireless communications, due to its low initial deployment cost, high scalability and flexibility, will play a key role in providing broadband communications to sparsely populated areas of Australia. To this end, the Australian government announced "Connect Australia" aiming for nationwide broadband communication services, in which wireless communications is an important component. This project focuses on improving the throughput of wireless communications, especially for rural areas, through the use of a new technology: semi-contention based multi-user diversity. The outcome of this project will help to connect Australian people and to lift the international profile of Australian engineering science in wireless communications.Read moreRead less
