Engineers at the University of Bristol, the UK, and the Swedish University of Lund in cooperation with technology company National Instruments have demonstrated wireless data transmission of 1.59Gbit/s.
This was achieved in a 20MHz channel and represents a 12-fold improvement over the fastest currently available 4G cellular technology.
MIMO is a multiple-antenna system used in existing Wi-Fi routers and 4G cellular phone networks. It usually relies on four antennas to cater for multipath propagation of the data signal. In massive MIMO, the number of antennas used in a single router is increased multiple times. The system used by the Bristol and Lund teams used 128 antennas.
"We see massive MIMO as the most promising 5G technology and we have pushed it forward together with partners in Bristol and in our EU project MAMMOET,” said Ove Edfors, professor of radio systems at Lund University. “It is a pleasure seeing those efforts materialise."...
