Multiple input, multiple output (or MIMO) technology increases the capacity of a mobile radio link by using multiple transmit and receive antennas to exploit multipath propagation.
ZTE and Telefónica carried out the trial at the latter’s headquarters in Madrid to assess performance in indoor coverage scenarios. ZTE said the test, the first of its kind to be carried out by Telefónica in Europe, had “exceeded expectations” by improving cell-edge data rate up to six times that of traditional LTE solutions.
During the test, the two companies ran a number of applications over the network including virtual reality and 2K streaming videos.
Enrique Blanco, CTO, Telefónica group, said: "We are very pleased with the results of the Pre5G Massive MIMO live trial with our partner ZTE, a recognised pioneer in the industry in this field. We see a lot of potential for this technology and the capability to bring a better experience for our customers.
“We believe Pre5G massive MIMO technology can solve the Internet’s last mile problem by improving Internet access and therefore enhancing the user experience. Massive MIMO will be a fundamental technological enabler for future 5G networks.”
