nbn hits 1.1 Gbps speeds in fixed wireless trial

nbn has achieved 1.1 Gbps speeds in a fixed wireless demonstration conducted in Ballarat, Victoria.

nbn hit 1.1 Gbps downstream and 165 Mbps upstream speeds by using carrier aggregation technology that fused seven carriers in the 3.4 GHz spectrum band and four carriers in the 2.3 GHz spectrum band.

As part of the demonstration nbn also delivered trial peak speeds of 400 Mbps/55 Mbps, 250 Mbps/50 Mbps and 100/40 Mbps, all delivered using a range of carriers in the 2.3 GHz and 3.4 GHz spectrum bands.

The 1.1 Gbps speed was achieved by bonding together three next-generation Wireless Network Termination Devices (WNTDs) — the antennae located on the roof of a nearby school — while the other speeds were all achieved via a single WNTD.

The trial was conducted with nbn’s fixed wireless technology partner Ericsson along with NetComm Wireless and Qualcomm while the speed tests were conducted with technology from Mill Software.

In order to conduct the trial nbn used a spare operating sector on an established nbn Fixed Wireless tower and installed additional radio equipment.
