About the research area Wireless systems

 
The need to densify the cellular network will increase dramatically in the coming years. The sharp increase is driven by growth in smartphone subscriptions, and at the same time we are consuming more mobile services as an increasing number of services are made available. A very large number of new devices are also expected to communicate in the mobile network, in areas such as infotainment, transport and new industrial applications.
 
The future wireless network will form the foundation for an intelligent society where people and equipment can be connected anywhere, anytime – with anything. A high degree of connectivity will be a key enabler for new innovative technologies and applications that can benefit from information sharing.

Research projects

Ongoing projects

> MUSIC; Multistream Wireless Backhaul
The goal of the MUSIC project is to lay the foundation for the next generation wireless backhauling networks, meeting the requirements in the next decade...
 
> Antennas for MIMO terminals and relays
The core of the research is the design of multi-port antennas, e.g., several antennas positioned close to each other, is a challenge for modern wireless communications systems. The challenges associated with the design of multi-port antennas can be linked to the coupling between different elements...
 
We focus on what wireless systems might look like 10-15 years from now, if certain technological constraints are lifted. We then see integrated wireless systems that may cover perhaps a whole city center, with thousands of radio transmitters/receivers working in a very tightly coordinated ways...
 
One of the most critical challenges with the establishment of HetNet is interference, since the creation of more cells implies that more cell edge users are prone to inter-cell interference (ICI) from neighboring cells. One way to reduce ICI is by changing the base-station antenna array characteristics (beamwidth, beampointing direction, beamshape etc)...
 
In this project, we investigate the potential of two emerging technologies in the area of wireless communications. More specifically, we explore the concept of large-scale (or massive) MIMO systems which are anticipated to deploy base-stations with hundreds of low-power antennas...
 
> METIS; Mobile communications Enablers for Twenty-twenty (2020) Information Society
The aim of the project is to lay the foundation for the next generation of the mobile and wireless communications system. METIS is a consortium of 29 partners spanning telecommunications manufacturers, network operators, the automotive industry and academia...
 
> Smart Wireless Networking for Green ICT
The traffic explosion in mobile internet puts new challenges on future mobile access networks. Forecasts predict 50 billion connected devices and a required thousand‐fold increase in network capacity. Such future wireless access networks will enable the intelligent society...
 
> Efficient Load-Aware Dynamic Global Radio Resource Management in Multi-Spotbeam BB Satellite Networks
Frequency re-use over a high number of narrow spotbeams is the key enabling solution towards the terabit/s satellite capacity in future broadband satellite communications. In this context, the adopted frequency plan plays a key role in determining the system performance...

Closed projects

 > ARTIST4G; Advanced radio interface technologies for 4G systems
The main objective of the ARTIST4G project is to improve the ubiquitous user experience of cellular mobile radio communications systems by satisfying the following requirements: High spectral efficiency and user data rate across the whole coverage area; Fairness between users; Low cost per information bit; Low latency...

This research project puts focus on modulation and coding schemes for Gbit/s Plesiochronous Digital Hierarchy (PDH) links with a short- to medium-term application horizon, Gigabit Ethernet based microwave radio links and networks, and more long-term research on packet based microwave backhauling networks...
 
The mission of this center is to produce world-class research in the area of wireless high data rate communications. We will provide optimized system solutions that take all relevant aspects of the physical communication process into account...
 
> IMT-advanced mobility; Mobility management, control and routing technology for IMT-Advanced and beyond
The scope of this project is on mobility management, control and routing in novel network topologies based on cooperating distributed multiple antenna systems...
 
> WINNER+; Wireless World Initiative New Radio+
​In order to reduce fragmentation and to ensure a competitive European position in the global context, the big collaborative project called WINNER+ was launched involving leading manufacturers, operators, and academic partners in Europe, but also partners outside of Europe...
