Optus claims milestone in 5G carrier aggregation

Optus has made what it claims is the world’s first 2300 + 3500 MHz 5G non-standalone carrier aggregation call.

According to Optus, the call — which was made in Sydney in collaboration with Ericsson and using Samsung’s Galaxy S20 5G handset range — demonstrated the benefits of simultaneous use of both spectrum frequencies simultaneously, ie, a significant increase in average and peak 5G speeds.

The capability will be made available across Optus’s Sydney and Melbourne 5G dual-band network later this year. Optus says it has so far rolled out 5G to more than 900 sites.

“When using carrier aggregation, customers will see an improved experience when using data-hungry applications and services, such as high-resolution video streaming, AR/VR and downloading large files,” said Lambo Kanagaratnam, Optus Managing Director Networks.
