Optus confirms trials of Massive MIMO and 3C technologies on live network

29 Sep 2017

Australian mobile network operator (MNO) Optus has announced a successful test of a combination of Massive MIMO (Multiple Input Multiple Output) and tri-band carrier aggregation (3C) technologies over its live network. In a press release outlining the development the cellco noted that that the network trial had actually been conducted on live traffic at Macquarie Park in Sydney back in June 2017, attaining a peak downlink speed of 818Mbps. Having carried out the trial in partnership with Chinese vendor Huawei, Optus claims the development meant it was the first operator in the world to complete a successful combined live network implementation of Massive MIMO and 3C technologies together in the same setting. The Massive MIMO Integrated Antenna system used was reportedly capable of delivering ‘64T64R MIMO, supporting up to 80MHz of all four carriers of Optus’ 2300MHz TDD band’.

Dennis Wong, Managing Director of Optus Networks, said of the matter: ‘We’re committed to leading Australia in terms of 5G development and testing, and this recently completed world-first 3C Massive MIMO test is further testament to our commitment and developments we have been able to achieve in this space. Site capacity during the live testing was significantly improved by almost four times compared to that of legacy 4T4R MIMO base stations.’

Looking ahead, Optus has said it plans to roll out Massive MIMO sites in selected capital cities from the end of 2017.
