EIT records in spectrum efficiency. 

Lund University (EIT) and Bristol University together break new grounds in the field of spectrum efficiency with a 128-antenna array in a prototyping platform from National Industries.

Compared to existing 4G-platforms, the team shows around 22 times better capacity using 256-QAM modulation, a shared 20 MHz radio channel at 3,51 GHz  and a 128-antenna M-MIMO-array.  Eight researchers and postdocs from Bristol and Lund demonstrated this and from Lund Liang LiuSteffen Malkowsky and Joao Vieira participated. 

The team beats their own earlier record and another one from Facebook with 24 users and a 96-antenna array. A 1000 fold increase in network capacity compared to 4G is claimed needed to meet future 5G-needs. Massive MIMO, mmWave and beamforming are technologies that will contribute and our Lund researchers are key persons.
