Ericsson goes Massive with Lund University

Today, Ericsson and Lund University are happy to announce a multi-year collaboration agreement regarding research and development in key technologies for mobile communication systems, mainly Massive MIMO technologies and applications.

MIMO (Multiple Input, Multiple Output) technology has been used in wireless communications for a long time. Now with shorter wavelengths used in 5G systems, and the rapid development in semiconductor technology, it is becoming feasible to develop MIMO-based solutions with hundreds of active antenna elements. The industry term for this is “Massive MIMO” or “MMIMO” for short.

MMIMO does not only enable a super-efficient and super reliable communications link but also other applications such as positioning, ranging and even radar-like functions.

As a leader in digital, wireless infrastructure products and services, MMIMO is an obvious research topic for Ericsson and we are now augmenting our internal research with that of the excellent teams at Lund University.

Lund University, largely through the work of professors Fredrik Tufvesson and Ove Edfors, has been active in MMIMO research since 2011. They built the world’s first real-time MMIMO testbed and with it set a new world record in wireless spectrum efficiency two years ago with 146bits/second/hertz in a collaboration with University of Bristol.

Electrical and Electronics Engineering is a strength of Lund University, and it was recently ranked #20 in the world in this discipline by Shanghai Ranking, far ahead of many prestigious universities.

The collaboration verifies the strength and breadth of our 5G-related research. There are few places globally where theory, system design and chip construction are done at this level. The breadth means we can take it all the way from theory to chip, says Viktor Öwall, Dean of Faculty of Engineering, Lund University.

The strong bond between Ericsson and Lund University goes back to the mid-1980s when Ericsson established an R&D office for mobile phone development in Lund, Sweden. Over the years, Ericsson and Lund University have collaborated on a range of research projects, such as EASE, or the Industrial Excellence Centre for Embedded Applications Software Engineering, and SoS, the Industrial Excellence Center in System Design on Silicon.

But the agreement we are announcing today is by far the largest and most ambitious collaboration yet, and we’re excited to get started.
