Wireless - Telecommunications Engineering Research
Wireless systems are easy to install – easier than digging trenches or suspending fibre from poles. Due to the congestion of the airwaves, moving obstacles and our desire to communicate anywhere, anytime, wireless systems have become incredibly complex, relying on sophisticated signal processing to maintain the information flow.
Our wireless group has made significant advances in the Orthogonal Frequency Division Multiplexing (OFDM) coding techniques used in Digital TV broadcasting and third generation (3G) cellular telephony systems. We are also working on sensor networks, where many sensors communicate with one another to relay information back to a base station, while maximizing battery life. We have also contributed to the standardisation efforts of IPv6 protocol suite. Fourth generation (4G) mobile/cellular systems will rely on IPv6 for seamless integration with the internet.
A major research theme of the wireless group is Radio Frequency Identification (RFID), where we are developing applications with local companies including bank-note security and asset-tagging.
