Optus completes infield test of Massive MIMO in partnership with Huawei

2 Mar 2017

Australian mobile network operator (MNO) Optus has announced the completion of a successful infield test of Massive MIMO (128T128R) technology in partnership with Chinese vendor Huawei. In a press release, the cellco noted that the trial achieved aggregate cell throughput of 665Mbps over a single frequency channel of 20MHz on Optus’ 2300MHz frequency band, shared by 16 devices. Further, the trial – which used Huawei’s Massive MIMO AAU solution, which has 16 beamforming streams in a 128T128R configuration – demonstrated an aggregated speed improvement of up to eight times when compared to what is currently being provided via existing 4G cell sites, while increasing the cell site capacity within the same spectrum channel. Finally, Optus said that in addition to overall aggregated speed improvements, the Massive MIMO testing had also indicated a significant improvement to areas with high density populations, with the new beamforming function.

Commenting on the development, Dennis Wong, Managing Director, Optus Networks, said: ‘Massive MIMO is an important technology enabler and lays the foundation for the upcoming 5G. We are proud to have successfully taken this next step towards 5G with our partner Huawei … Earlier this month, we launched the 4.5G network in Macquarie Park. Today’s announcement showcases our dedication to launching a world-class 5G network in Australia and shows how we are leading the field in testing the technology.’
