Australian state-owned broadband wholesaler aggregates 11 carriers of 3.4-GHz, 2.3-GHz spectrum.

Australia’s NBN this week achieved gigabit downlink speeds in a fixed wireless trial.

The state-run broadband wholesaler used carrier aggregation technology to combine seven carriers in the 3.4 GHz band with four carriers in the 2.3 GHz band, achieving 1.1 Gbps on the downlink and 165 Mbps on the uplink.

The trial took place in Ballarat, Victoria.

"The company continues to demonstrate its focus on providing technology to meet today’s demands while ensuring a strong path of development and upgrades to meet Australia’s future data demands," NBN said, in a statement on Wednesday.

The trial was conducted in partnership with Ericsson, NetComm Wireless and Qualcomm.

NBN plans to launch a 100-Mbps fixed wireless service pitched at the regional business segment in 2018.

"The success of its ultrafast fixed wireless demonstration underlines the company’s ability to launch even faster services on the NBN fixed wireless network," NBN said.
