Future radio research


​We help our customers to meet 5G communication requirements

VTT's new research results enable high date rates and high capacity mobile communication and low latency, reliable, low energy and low cost connections.

Our research focus areas are 5G system design and architecture, air interfaces, solutions for new spectrum areas including millimetre wave frequencies, cognitive radio resource and network management, security and dependability, software-defined networking and virtualisation, energy efficient hardware including antennas, RF and digital electronics and software technologies, testing technologies, and business models.

We also help customers to verify new concepts with our 5G system simulator and national test bed. In addition, our active work in regulation and standardisation forums will improve the dissemination of research results and support customers in their product decisions.

Solutions for different challenges

Future 5G system architecture enables several use cases and application requirements beyond 2020. It will be a common infrastructure for traditional mobile multimedia communication, satellite communication and massive machine-type communications addressing consumers and professional users in vertical industries. Although 5G will require radical architecture-level changes and disruptive technologies, it will also enable the smooth migration from current system architecture and technologies.

A key part of the 5G system is its flexible and adaptive air interface, which supports a different type of services, MIMO capabilities, and several device types. It will also enable different areal settings and flexible spectrum usage. In addition, mm-wave air interface and system architecture will be an integral component of 5G, enabling very high quality multimedia and cloud-based services and dynamic use of millimetre wave frequencies for ultra-dense network deployment.

From a system performance and usability point of view, cognitive radio resource and network management concepts, algorithms and solutions will also play a critical role. Radical improvement in the use of radio resources, especially spectrum occupancy and support for self-management, co-operation and coexistence will be needed.

Implementation architectures and technologies will provide sufficiently flexible performance for end user devices, access points and other network equipment at same time as the minimisation of materials and energy consumption. The integration of our communication methods knowledge and platforms and equipment implementation competencies with testing technologies knowledge will be the key for winning system and product concepts.
