Uplink speed record set by Ericsson

Ericsson has teamed up with Telstra and Qualcomm to achieve the highest uplink peak rate ever recorded using 5G dual connectivity and carrier aggregation.

Using Ericsson’s New Radio-Dual Connectivity (NR-DC) software, a smartphone test device powered by Qualcomm’s Snapdragon X65 5G Modem-RF System on Telstra’s network at a live demo site in Queensland, Australia, the team reached a record uplink data speed of close to 1Gbps.

Delivering uplink peak rates of close to 1Gbps will enable Telstra to more than double the current uplink throughput in its 5G network according to the company. This can be used to support applications and services that involve uploading vast amounts of data including live video streaming and extended reality (XR).

Achieving the theoretical maximum uplink speed of 986 Mbps during the test came by integrating four contiguous component 100MHz carriers of millimeter wave, combining with the 100MHz of 3.6GHz spectrum across 5G New Radio (5G NR) frequency. The high uplink peak rate was reached by combining the data rates from both mid-band and high band.

Sibel Tombaz, head of product line 5G RAN at Ericsson, said: “We continue to pursue new and innovative ways of enhancing the end-user impact of 5G.
