Research Overview
Millimetre-wave (mmWave) communications typically operate in the 30–300 GHz frequency range. The availability of wide frequency bands makes mmWave technology attractive for high-data-rate wireless links, including advanced mobile networks and wireless backhaul.
Short wavelengths enable compact antenna arrays and highly directional beamforming, which can improve received signal strength and limit interference. However, mmWave links are more sensitive to blockage, propagation loss and environmental conditions than many lower-frequency links. Research therefore focuses on accurate channel modelling, antenna design, beamforming and hybrid analogue–digital transceivers, as well as reliable link-budget analysis.
