Optus introduces 4.5G connectivity in Sydney’s hi-tech district

22 Feb 2017

Australian mobile network operator (MNO) Optus has taken what it terms ‘a step towards 5G’ with the switch-on of ‘4.5G’ network services across the suburb of Macquarie Park, Sydney’s hi-tech innovation district. Announcing the development in a press release, the cellco revealed that tests achieved throughput speeds of 1.03Gbps by utilising a combination of technologies, including four and five component carrier aggregation (4CC/5CC), 4×4 MIMO and 256-QAM. Optus has said it aims initially to roll out 4.5G services in selected capital cities, while within the next twelve months it hopes to have deployed the enhanced connectivity to over 70% of its existing network in Sydney, Melbourne, Brisbane, Perth and Adelaide.

Dennis Wong, Managing Director of Networks at Optus, said: ‘Ultimately, the launch is a step closer to Optus being able to deliver 5G network speeds to customers and [we] will continue to invest in R&D and our partnership with Huawei to achieve this.’
