Ericsson, Telstra, Qualcomm set uplink speed record close to 1 Gbps
Ericsson, Telstra and Qualcomm Technologies, Inc. achieved the highest peak uplink speed ever on a commercial network during a live demo in Queensland, Australia. Together, they achieved an uplink data rate of nearly 1 Gbps, paving the way for more seamless experiences in use cases such as live video streaming and social media sharing.
Utilizing Ericsson’s New Radio-Dual Connectivity (NR-DC) and carrier aggregation software features along 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 an new important milestone for the ecosystem cooperation between the three companies.
The high uplink peak rate was achieved by combining both the midband and highband (millimetre wave) data rates to fully utilize Telstra’s spectrum for an enhanced user experience. The demo took advantage of Ericsson’s NR-DC software feature with uplink four-component carrier aggregation (UL 4CC CA), which combines four contiguous 100 MHz carriers, resulting in faster data rates.
By delivering peak uplink speeds of nearly 1 Gbps, Telstra can more than double the current uplink throughput in its 5G network. This is especially important for supporting applications and services that require large amounts of data to be uploaded.
Sibel Tombaz, Head of Product Line 5G RAN, Ericsson, said: “We continue to look for new and innovative ways to increase the end-user impact of 5G. An uplink speed of almost 1 Gbps using NR-DC and four-component carrier aggregation is the latest in a series of 5G milestones we have achieved in partnership with Telstra and Qualcomm Technologies. This means users can enjoy vastly improved experiences from applications where faster upload time makes a difference.”
Nikos Katinakis, Group Executive Networks and IT, Telstra, said: “We have a history of world firsts with Ericsson and Qualcomm Technologies. In 2016 we broke the 1Gbps barrier on 4G; in January of this year we set a new download record on 5G, and now we set a new record in the uplink on a commercial 5G network. It’s a testament to our team’s continued efforts to innovate, and I’m proud of how we continue to push the boundaries of what this technology can deliver together.”
Sunil Patil, Vice President, 5G Product Management, Qualcomm Technologies, said: “Qualcomm Technologies is excited to partner with Ericsson and Telstra on this 5G milestone with dual connectivity and carrier aggregation. By achieving the highest uplink peak rate ever recorded on a commercial network in Queensland, Australia, we underline our commitment to enabling differentiated 5G experiences for a variety of use cases beyond mobile. Together, we are realizing the full potential of 5G through new breakthroughs that will deliver transformative benefits for both consumers and businesses.”
Ericsson, Telstra and Qualcomm Technologies achieved first on a commercial network in Queensland, Australia with a theoretical maximum uplink speed of 986 Mbps, integrating four components 100 MHz millimeter wave carriers, combined with the 100 MHz of 3.6 GHz spectrum . NR-DC is implemented with n78 and n258.
The tests were conducted at Telstra’s 5G Innovation Center (5GIC) using Telstra’s commercial network, resulting in throughputs of approximately 1 Gbps, more than doubling the current uplink speed on the market. The smartphone form factor test device powered by Snapdragon X65 was used with Ericsson Radio System’s Baseband 6648 and AIR 6488 for mid-band, which has been widely deployed in Telstra’s network, and Baseband 6648 with the AIR 5322 for high-band.
Ericsson’s NR-DC software combines 5G frequency ranges below 7.125 GHz (mid-band, Time Division Duplex, TDD) and above 24.25 GHz (high-band TDD) and is now available for commercial deployment. The UL 4CC carrier aggregation software is expected to become commercialized worldwide in the second quarter of 2022.
