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. 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 environment. We are collaborating with Internet service providers in regional Australia to trial systems currently being developed. In the process we will develop a new technology that will provide training for young engineers.Read moreRead less

Infrastructure for wireless Internet technology development for rural Australia. Three nodes of a low-power, very-high frequency digital wireless network will be installed at two locations in the Australian National University and one location at the University of Canberra. An additional node will then be located a further distance away (> 50 kms) in the ACT. This network will allow the development of novel technology for moderate speed (>100 kbps) non-line of sight wireless Internet access o ....Infrastructure for wireless Internet technology development for rural Australia. Three nodes of a low-power, very-high frequency digital wireless network will be installed at two locations in the Australian National University and one location at the University of Canberra. An additional node will then be located a further distance away (> 50 kms) in the ACT. This network will allow the development of novel technology for moderate speed (>100 kbps) non-line of sight wireless Internet access over ranges of 3-100 km for potential use by regional Australian Internet providers. The network will also catalyse research and training in wireless communication technology , digital signal processing, and computer networking.Read moreRead less
Smart Antennas for Broadband Wireless Data Systems. Smart antennas can facilitate accommodation of an increasing demand for bandwidth and quality in wireless communications by directing the antenna beam towards the desired user, while suppressing signals coming from interferers. The beam forming processor can adapt to changes in channel propagation conditions as well as movements of the user or interferers. Many algorithms for controlling smart antennas have been proposed, and usually there is a ....Smart Antennas for Broadband Wireless Data Systems. Smart antennas can facilitate accommodation of an increasing demand for bandwidth and quality in wireless communications by directing the antenna beam towards the desired user, while suppressing signals coming from interferers. The beam forming processor can adapt to changes in channel propagation conditions as well as movements of the user or interferers. Many algorithms for controlling smart antennas have been proposed, and usually there is a trade-off between complexity and performance. We aim to find a suitable compromise to implement smart antennas for broadband wireless access systems and to apply smart antenna technology to increase the range of ultra-wideband communications.Read moreRead less
Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and ....Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and an increase of interference. The aim of this project is to demonstrate an alternative method of maintaining good quality communication link. The proposed method employs a smart antenna system to mitigate adverse effects of multi-path and interference.Read moreRead less

Adaptive Modulation For OFDM Signals. The sub band Signal To Noise Ratio in an OFDM communications channel varies by as much as 30 dB. In order to optimise the bandwidth efficiency of OFDM signalling it is desirable to adapt the chosen modulation technique such as M-ary QAM to the SNR available in sub bands. In this way high quality channels transmit the highest bit rates, whilst low quality channels accommodate the lowest bit rates. The net result is that the capacity of the communications link ....Adaptive Modulation For OFDM Signals.
