Optus and Huawei achieved a single-user transmission speed of 35 gigabits per second during a 5G trial using spectrum in the 73GHz band.
The Sydney trial was aimed at exploring spectrum efficiency at frequencies above 30GHz, Optus said.
“Australia is well positioned to take a pioneering role in the development of 5G technologies globally,” Optus Networks acting managing director Dennis Wong said in a statement.
“We believe Optus, as one of the Australasia’s leading telecommunications and entertainment providers has the partnerships and the expertise to take a leadership position.”
In 2014 Optus’ parent company, Singtel, and Huawei signed a memorandum of understanding (MoU) for a joint 5G innovation program.
Last month Optus and Nokia announced they had also signed an MoU, with the two companies planning an “early 5G prototype” using the telco’s 3.5GHz spectrum holdings.
Optus said that it was already working on 5G precursor technologies, deploying inter-site carrier aggregation at the AFL Grand Final in October and planning later this year to trial Massive MIMO (multiple-input and multiple-output).
Australia’s three mobile carriers have all conducted local 5G tests.
In September, Telstra and Ericsson staged Australia’s first public demonstration of 5G technology. The demo employed 800MHz of spectrum in the 15GHz band, delivering 10Gbps data streams to two end user devices.
In October Vodafone and Nokia staged a 5G trial at the University of Technology Sydney. That trial leveraged spectrum in the 4.5GHz band.
