New technology for efficient and speedy wireless data transfer is under development at the Aalto University School of Electrical Engineering. The aim is to develop new basic structures for the wireless network that might revolutionize the concept of mobile equipment.
In the traditional wireless technology, it is not possible to send and receive data on the same frequency simultaneously as the strong transmission signal will drown out the incoming signal. The aim of the technology currently under development, which is based on the multiple-input and multiple-output (MIMO) technology, is to reduce this interference.
‘The main aim of the project is to develop a compact transmitter-receiver based on MIMO technology that would allow simultaneous sending and reception of data on the same frequency band,’ explains Professor Risto Wichman from the School of Electrical Engineering.
In his view, the full-duplex technology currently under development will significantly improve the spectral efficiency of the mobile network, which would mean a higher overall network capacity.
The project is unique because it combines different areas of antenna design, digital signal processing, radio frequency techniques and communication theory. It will be carried out in collaboration with the Tampere University of Technology and there is also cooperation with the University of Nice, the Drexel University and the Rice University in the United States, the Kyoto University in Japan and the Universidad Nacional del Sur in Argentina. TIVIT, Finland’s Strategic Centre for Science, Technology and Innovation in the field of ICT, is supporting the implementation of the project.
