Achieving 1 Gbps speeds using 5G dual connectivity

20 January 2022

Ericsson, Telstra and Qualcomm Technologies have achieved what they claim is the highest uplink peak rate ever recorded on a commercial network.

The companies reached an uplink data speed of close to 1 Gbps, something that could enable use cases such as instant live video streaming and social media content sharing.

The demo, which took place in Australia, used Ericsson’s New Radio-Dual Connectivity (NR-DC) and carrier aggregation software features together with a smartphone form-factor test device using Snapdragon’s X65 5G modem-RF system on Telstra’s network, a telecom in Australia.

The demo also used Ericsson’s NR-DC software feature with uplink four-component carrier aggregation, in which four contiguous carriers of 100 MHz are combined, resulting in higher data speeds. Delivering uplink peak rates of close to 1 Gbps will allow Telstra to more than double the current uplink throughput in its 5G network.

“We continue to pursue new and innovative ways of enhancing the end-user impact of 5G,” said Sibel Tombaz, head of product line 5G RAN at Ericsson. “An uplink speed of close to 1 Gbps using NR-DC and four-component carrier aggregation is the latest in a series of 5G milestones we have achieved in collaboration with Telstra and Qualcomm Technologies. This means users can enjoy vastly improved experiences from applications where quicker upload time makes a difference.”
