Professor of Communications Engineering Matti Latva-aho has his research focus on high frequency wireless communication systems and 5G technology development. Wireless data communications systems and networks are already central to the effective functioning of society, and their significance is continuing to increase. The capacity of wireless communications networks is ultimately constrained by limited spectrum availability. Under current plans, new spectrum allocations for mobile data communications will only be made at much higher frequency bands than those used at present. This will bring major changes to how future wireless radio systems should be planned and optimised. Latva-aho’s research will help to improve understanding of how the design criteria for future wireless systems will change and what kind of transmission technologies and transmitter/receiver architectures they should use. His work will address and resolve challenges whose existence has been recognised but not seriously tackled in earlier research. It is expected to generate significant new information in the field of data communications technology. The project will create a basic understanding of millimetre wave technologies and design an ultra-high-capacity data communications network architecture for the future.
