As a means to increase the spectrum efficiency and network capacity, Vodafone UK conducted a trial of massive MIMO (multiple input and multiple output) in Europe with the help of Huawei, its technology partner in the initiative. The test has been successful and the duo will continue the trials on commercial networks, said Vodafone UK and Huawei.
“We continue to test the technology, as we believe Massive MIMO could benefit many of our customers, particularly in areas where there are a large number of devices, such as city centers, train stations, business districts and stadiums,” Huawei said in a release.
MIMO is a technique that enables operators to make better use of existing infrastructure and spectrum assets. Vodafone UK considers 4×4 and 8×8 MIMO as an important part of its network evolution as it moves towards 5G deployments. The massive MIMO is capable of focusing the signal into a more precise set of layers. This makes the data transmission more efficient. These layers can bring more capacity than current 4G systems with the same bandwidth and Massive MIMO is also capable of ‘full dimensional beamforming’, which means it can direct beams both horizontally and vertically.
The MIMO technology trial was conducted on 2.6 GHz TDD spectrum on Vodafone’s commercial network in Newbury.
