Telecom network and software maker Huawei has completed the Massive MIMO verification test using SoftBank’s 40 MHz spectrum on the 3.5 GHz band in Tokyo, Japan.
SoftBank and Huawei adopted Massive MIMO and multi-carrier technologies with the peak downlink rate reaching 1.4 Gbps.

The technology company said Massive MIMO, featuring the incorporation of massive antennas and 3D beamforming, enhances spectrum multiplexing among multiple UEs to improve spectral efficiency without additionally site density or bandwidth.
The 3.5 GHz Massive MIMO test further explores the latent potential of 3.5 GHz spectrum, and is expected to open up a new commercial era of LTE-Advanced.
Traffic at SoftBank has increased by 2,300 times within the last ten years. SoftBank, in order to handle data traffic, has deployed a number of commercial Massive MIMO sites at key locations in Tokyo, Osaka, and Nagoya since September 2016.
In February 2017, Huawei received secured the lead in completing massive MIMO+multi-carrier verifications on the 3.5 GHz band, consolidating SoftBank’s technological advantages in network deployment using 3.5 GHz spectrum.
