Australian mobile network operator (MNO) Optus claims to have made the world’s first ‘2300MHz + 3500MHz 5G Non-Standalone Carrier Aggregation call’. In a press release regarding the development, the cellco said that the call – which it made in Sydney in collaboration with technology partner Ericsson and using Samsung’s Galaxy S20 5G handset range – demonstrated the benefits of utilising both spectrum frequencies simultaneously. Specifically, it claimed that these include a ‘significant’ increase in the average and peak 5G speeds that customers with an eligible handset (local compatible variants of the Galaxy S20 5G and the newly launched Galaxy Note20 5G) would receive, as the capability becomes available across what it referred to as its ‘5G Dual Band’ network in Sydney and Melbourne later this year.
Commenting, Lambo Kanagaratnam, Managing Director Networks at Optus, said: ‘5G Carrier Aggregation is a significant technology milestone that provides us with the ability to combine two spectrum frequencies to improve and extend the coverage, speed and capacity of our 5G network … We are ambitious in our 5G network rollout and together with our technology partner, Ericsson, this testing has further demonstrated how carrier aggregation can and will play an important role in optimising the capacity of our network.’
The MNO noted that to date it has rolled out 5G to over 900 sites in Australia, with its network now covering ‘more than 426,000 households’.
