Optus Showcases 5G FDD, TDD Carrier Aggregation

Optus has achieved another 5G milestone by combining 2100 MHz spectrum with 3500 MHz spectrum for the first time, through the use of 5G carrier aggregation and spectrum sharing technology.

Working in tandem with partners Ericsson and Samsung the testing was completed at a live 5G site on non-stand-alone architecture in Sydney using a Samsung S21 device.

The combination of 5G FDD 2100MHz and 5G TDD 3500 MHz allows the simultaneous use of both 5G and 4G, enabling faster data speeds and improved network performance.

Optus currently has more than 1000 5G sites across Sydney, Perth, Melbourne, Brisbane, Adelaide and Canberra, as well as key areas outside of these cities.
