The quest for highly efficient 5G wireless connectivity has been given a boost thanks to a collaboration between a team of 5G engineers from the Universities of Bristol and Lund, National Instruments (NI), and BT Labs, one of the world’s leading providers of communications services. The research team has undertaken field trials of a massive MIMO system at the BT Labs in Adastral Park, Suffolk. The trials were conducted in a large indoor hall mimicking a stadium environment and outdoors within the Adastral Park campus.
