Radio system design and prototyping


​We help our customers to design and validate functionality and performance of radio systems

VTT's competencies and solutions enable improvement in system capacity and power, spectrum- and cost-efficiency of radio systems, and reduced interference and detectability in wireless communication. To support the system design phase, VTT has competencies in methods, protocols and architectures for advanced system and networking concepts, and strong skills and tools for specification, design, and simulation at radio link and system level.

For the prototyping phase, VTT is able to provide state-of-the-art, real-time implementation knowledge, design tools and testing environments. Our implementation competencies cover antenna, RF and digital hardware and software design, integration and testing. The role of programmable hardware, multicore processor and parallel processing in high-speed and flexible equipment implementation is increasing.

VTT will speed up the customer design process and reduce design cost by using its programmable and configurable link and system-level testing environments.VTT's flexible software-defined radio platforms and environment based on channel emulators can be used in link-level testing, and both base station (LTE) and multi-access (3G, LTE, WLAN, WiMAX) network testing environments are available for system-level projects.

Meeting various challenges

We have developed methods and prototypes for joint optimisation of capacity, energy efficiency, coverage and quality, cross-layer design and adaptive transmission, intra- and inter-system interference management and mitigation, dynamic spectrum management and advanced networking concepts including mesh, grids, relays, co-operating and cognitive access networks and terminals.

Our competencies and technologies have been applied to mobile, machine to machine, Internet of Things, military, and satellite communication systems.  We have worked mostly with the following standards:  3GPP HSDPA, HSUPA, HSPA+, 3GPP LTE and LTE-A evolution and IEEE 802.11, 802.15, 802.16, 802.22 evolution and ECMA-368 and ECMA-387.

We have especially extensive experience in the development and prototyping of adaptive multi-carrier techniques, including systems based on orthogonal frequency division multiplexing (OFDM) and orthogonal frequency division multiple access (OFDMA). Our key challenge in recent years has been the development and prototyping of adaptive and cognitive methods reducing energy consumption and interference and improving capacity, latency and energy efficiency of radio systems.
