Strategic goal: long-term development of RF technology knowledge for 5G and beyond
State-of-the-art radio frequency transceivers are highly programmable but still physically constraint elements in wireless systems that enable and restrict capabilities of future communications. Flexibility in applications envisioned for 5G pose very diverse requirements for RF design. Extremely high data rates, carrier frequencies up to 100 GHz or even more and demand for power and cost efficiency are trade-offs in high-end solutions for infrastructure and mobile devices. On the other hand, extremely low power radios for IoT require dedicated electronics design techniques as well as capability to trade-off performance constraints optimally for each application. Modern RF transceiver design takes requirements coming from user demands and recent radio access research and constructs new RF architecture concepts for new 5G applications with in depth implementation studies. For comprehensive understanding prototype implementations including RFIC’s (radio frequency integrated circuits) are needed and boundary conditions are provided for radio access and digital signal processing research towards holistic system optimization. Also, modern RF design includes use of various digital signal processing techniques and algorithms for control and compensation of RF non-idealities whenever possible.
University of Oulu and Nokia Mobile Networks has several ongoing research projects in RF technologies, including bilateral and EU funded projects.
- 5GChampion (joint co-operation between EU and Korea) – CWC and Nokia are developing state of the art RF for 24-28 GHz frequencies, delivering 5G proof-of-concept demo to 2018 Winter Games.
- Bilateral project on integrated RF transceivers towards 5G radios, develop key technologies for advanced mm-wave solutions.
