nbn, the company overseeing Australia’s National Broadband Network (NBN) project, claims to have achieved ‘ground-breaking gigabit speeds’ in a demonstration of fixed-wireless technology. The trial, which was conducted in Ballarat, Victoria, recorded a downlink rate of 1.1Gbps and an upstream rate of 165Mbps by using carrier aggregation (CA) that fused seven carriers in the 3.4GHz spectrum and four carriers in the 2.3GHz band. As part of the demonstration nbn said it had also delivered trial peak speeds of 400Mbps/55Mbps, 250Mbps/50Mbps and 100/40Mbps, by using a range of carriers in the aforementioned bands. It also noted that the peak 1.1Gbps speed had been achieved by bonding together three next generation Wireless Network Termination Devices (WNTDs), while the other speeds were all reached via a single WNTD. The high speed trial was conducted in partnership with Swedish vendor Ericsson, NetComm Wireless and Qualcomm, while also using technology from Ozzie software developer Mill Software.
Commenting on the development, nbn CEO Bill Morrow said: ‘Our ability to deliver gigabit speeds on fixed-wireless demonstrates our continued focus on identifying and implementing tech advancements as and when they are needed, across all technologies … This also underlines the importance of nbn’s spectrum in the 2.3GHz and 3.4GHz bands in allowing high speed services to Australians.’
