Optus - Australia

Optus Australia uses the UMTS band B8 (900 MHz GSM). This frequency band is deployed for both UMTS and LTE networks. The deployment of this band is part of Optus's strategy to enhance its 5G coverage, particularly in rural and in-building areas, where the 900 MHz spectrum can penetrate deeper and provide broader coverage.

Optus Australia uses LTE Band 1 (2100 MHz) in Darwin, Cairns, Hobart, and the Sunshine Coast. This frequency band was first deployed in 2013 in Canberra.

Optus Australia uses LTE B3 (1800 MHz +) in Brisbane, Sydney, Newcastle, Perth, Melbourne, and Adelaide. This frequency band is currently operating in these cities.

Optus Australia uses LTE B7 (2600 MHz) for its 4G network. This frequency band is being rolled out nationwide.

Optus Australia uses LTE Band 28 (700 MHz APT) for its 4G LTE network. This band operates between 703 MHz and 803 MHz, with a duplex spacing of 55 MHz. The uplink frequency range is 703–748 MHz, and the downlink frequency range is 758–803 MHz. Optus has deployed this band nationwide, with a bandwidth of up to 20 MHz.

Optus Australia uses LTE Band 40, also known as TD 2300 MHz, in big cities such as Sydney, Melbourne, Brisbane, Adelaide, and Canberra, plus selected metropolitan locations. This frequency band was first deployed in Canberra in May 2013.

Optus Australia uses LTE Band 8 (900 MHz) for its 4G network. This frequency band was added to Optus Australia's network on August 4, 2024.

Optus Australia uses the 5G NR frequency band n1, which covers the 2100 MHz frequency range. This band is used for both uplink and downlink operations, with the uplink ranging from 1920 to 1980 MHz and the downlink ranging from 2110 to 2170 MHz. The band supports various channel bandwidths, including 5, 10, 15, and 20 MHz. Optus has deployed this band to enhance its 5G network, leveraging its existing 3G and 4G infrastructure to support advanced 5G use cases such as virtual and augmented reality, real-time gaming, and IoT applications.

Optus Australia has activated its 5G NR N8 (900 MHz) frequency band to increase its 5G footprint and improve rural and in-building coverage. This technology update is expected to increase Optus's 5G coverage by 20% on a per-site basis. The deployment of the 900 MHz spectrum has been activated on close to 1,000 sites, with additional sites progressively rolling out across the country.

Optus Australia uses the 5G NR frequency band n40, which operates on the 2300 MHz band. This band is commonly referred to as the 2.3 GHz 5G band. Optus launched the world's first 2300 MHz and 3500 MHz dual-band 5G production network in February 2020, utilizing this frequency band.

Optus Australia has completed the world’s first 2.3 GHz + 3.5 GHz 5G non-standalone carrier aggregation call using the 3500 MHz frequency band. This deployment demonstrates the benefits of combining two spectrum frequencies to improve and extend the coverage, speed, and capacity of their 5G network. The call was made in Sydney, in collaboration with Ericsson and using Samsung’s Galaxy S20 5G handset.
