A statement from the company said the demonstration was carried out in Sydney using the Samsung Galaxy S20 5G handset range.
“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,” said Lambo Kanagaratnam, Optus managing director Networks.
“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.
“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.”
Optus said the demonstration showed "the benefits of utilising both spectrum frequencies simultaneously [which was] a significant increase in the average and peak 5G speeds that customers, with an eligible handset, will benefit from as the capability becomes available across Optus’ Sydney and Melbourne 5G dual band network later this year".
Martin Wiktorin, head of Ericsson Singapore, Brunei and the Philippines and Global Customer Unit Singtel, said: “Ericsson is pleased to be working with Optus in deploying 5G TDD-TDD carrier aggregation on 5G NSA. 5G TDD-TDD carrier aggregation on 5G NSA allows Optus to combine its mid-band spectrum to deliver its customers higher 5G peak speeds and is an important step towards building Optus’ 5G network."
“The Galaxy S20 5G and Note20 5G have introduced to our customers, a range of completely new experiences which extend from the handset design and chipsets, through to the incredible network performance in Australia,” said Garry McGregor, vice-president, Mobile Division, Samsung Electronics Australia.
“We are committed to working with our partners to build on many years of investment in calibrating our devices for the Australian market.”
