Massive MIMO

Massive MIMO has quickly established itself as a crucial 5G technology, particularly below 6 GHz where enhanced spectral efficiency is paramount. By focusing on spatial multiplexing, a massive MIMO system can provide a capacity increase in the order of 10-20x (compared to current LTE systems) by serving more users simultaneously in the same frequency resource.  Through close collaboration with Bristol Is Open (a joint venture between the University of Bristol and Bristol City Council), the CSN Group has experimental access to a 128-antenna real-time massive MIMO testbed. This platform is under joint-development with Lund University and National Instruments. Using this system, a team of postgraduate research students set the current world record for spectral efficiency. Our pioneering work in Massive MIMO has been recognised via a number of international awards.
