New research conducted at Lund University in Sweden and the University of Bristol in the UK has demonstrated 5G technology twelve times as efficient as the current 4G technology, paving the way for the mobile systems of tomorrow.
Researchers in Lund and Bristol have made enormous progress with their work on Massive MIMO (multiple-input multiple-output) – a technology which, in simple terms, consists of equipping every base station with hundreds of antennae instead of the few they currently have.
“What we have developed is an extremely efficient 5G technology. We have actually found the most efficient technology ever in terms of capacity to handle many users simultaneously. What is really new here is that it has been demonstrated in practice that this fantastic spectrum efficiency can be achieved”, says Ove Edfors, Professor of Radio Systems at Lund University’s Faculty of Engineering.
The research findings on more efficient mobile systems are the result of a collaboration, explains Edfors’ colleague Fredrik Tufvesson:
“This progress is based on work conducted over several years at Lund University, with our doctoral students and together with partners such as the University of Bristol, Linköping University, and within the EU project called MAMMOET.”
The next generation of mobile technology, 5G, is under development and the research on Massive MIMO is an important contribution to this.
“Lund and Bristol are now breaking world records in efficient 5G networks, or in spectrum efficiency to be precise”, says Professor Fredrik Tufvesson.

5G is expected to reach the market around 2020 and intensive standardisation work is currently ongoing for this next generation of mobile technology. Massive MIMO is one of the main technologies to achieve the capacities required by the mobile systems of tomorrow. The goal is a thousand-fold increase in capacity through a combination of several antennae on the base stations, more but smaller base stations and the exploitation of new frequencies.
