Australia's nbn, a state-owned company building the national broadband network, has completed a series of live LTE Fixed Wireless trials that could pave the way for an upgrade to 1Gbps broadband speeds in the country.

Using carrier aggregation, the company combined seven 3.4GHz carriers with four in the 2.3GHz bands to achieve 1.1Gbps downlink and 165Mbps upstream speeds. Nbn also demonstrated peak speeds of 400/55Mbps, 250/50Mbps and 100/40Mbps in separate device trials using different carriers across the two bands.

The trials were conducted in collaboration with Ericsson, NetComm Wireless and Qualcomm, using speed testing technology from Mill Software.

The results displayed the next potential steps for nbn Fixed Wireless which will be delivered to the Australian market as a fully managed nbn 100 Fixed Wireless commercial product in 2018 using Ericsson network technology and Wireless Network Termination Devices (WNTDs) engineered by NetComm Wireless, according to the company.

The nbn Fixed Wireless network differs from a mobile network in that it establishes a direct connection between the WNTD at the premises and Ericsson infrastructure to enhance capacity and provide a consistent level of broadband speed and performance, even in peak data demand periods.

The network has the capacity to support the future digital demands of regional Australia using Ericsson infrastructure, WNTDs from NetComm Wireless and Snapdragon X16 LTE modems from Qualcomm to optimise transmission bandwidth and the quality of experience for end users as demand for higher speed services continues to grow, nbn said.

WNTDs integrate a high-gain directional panel antenna using advanced MIMO to maximise cell performance and increase spectral efficiency. The devices feature advanced carrier aggregation capabilities for increased overall transmission bandwidth and network capacity. The NetComm Wireless Indoor Unit is designed to power the WNTD over Ethernet and deliver a high-speed broadband connection to the premises.
