Qualcomm & Ericsson enabling Telstra to achieve 1Gbps uplink

Qualcomm Technologies have combined with Ericsson and Telstra to achieve the highest uplink peak rate ever recorded on a commercial network, in the course of a live demonstration in Queensland, Australia.

Together, they reached an uplink data speed of close to 1Gbps, paving the way for more seamless experiences in use cases such as live video streaming and social media content sharing.

Using Ericsson’s New Radio-Dual Connectivity (NR-DC) and carrier aggregation software features together with a smartphone form-factor test device powered by Snapdragon X65 5G Modem-RF System on Telstra’s network, this new uplink speed record marks another significant milestone for the ecosystem collaboration between the three companies.

The high uplink peak rate was reached by combining the data rates from both mid-band and high band (millimetre wave) to fully utilise Telstra’s spectrum for improved user experience. The demo used Ericsson’s NR-DC software feature with uplink four-component carrier aggregation (UL 4CC CA), in which four contiguous carriers of 100MHz are combined, resulting in higher data speeds.

Delivering uplink peak rates of close to 1Gbps will enable Telstra to more than double the current uplink throughput in its 5G network. This is particularly important for supporting applications and services that involve uploading vast amounts of data.

Sunil Patil, Vice President, 5G Product Management, Qualcomm Technologies, Inc., said, “Qualcomm Technologies is pleased to collaborate with Ericsson and Telstra on this 5G dual connectivity and carrier aggregation milestone. 

“By achieving the highest uplink peak rate ever recorded on a commercial network in Queensland, we are underscoring our commitment to enabling differentiated 5G experiences across a variety of use cases beyond mobile.

“Together, we are realising the full potential of 5G through new breakthroughs that will drive transformative benefits for consumers and enterprises alike.”
