Ericsson and MediaTek have set a new 5G upload speed record of 440 Mbps in low-band and mid-band spectrum using Uplink Carrier Aggregation. The zippy uplink speed brings better, smoother experiences for the likes of video conference users, streamers, and their audience with more frames per second and higher image resolution.
The record uplink speed was achieved in an interoperability development test at an Ericsson lab. The test was performed with RAN Compute Baseband 6648 and a mobile device using MediaTek Dimensity 9200 flagship 5G smartphone chipset. The Uplink Carrier Aggregation combination involved a frequency division duplex (FDD) and time division duplex (TDD) channel, in a frequency range widely deployed in today’s 5G networks.
More precisely, the combination used was 50MHz FDD n1 and 100MHz TDD n77. By aggregating these two bands, communications service providers can considerably increase their uplink speeds, resulting in better network performance and user experience.
“Super-fast uplink speeds make a big difference in the user experience. From lag-free live streaming, video conferencing, and AR/VR apps, to more immersive gaming and extended reality (XR) technologies,“ said Sibel Tombaz, Head of the Product Line for 5G RAN at Ericsson. “The 440 Mbps upload speed achieved by Ericsson and MediaTek will help make that difference. We are also continually designing innovative solutions for optimizing 5G networks so our customers can make the best use of their spectrum assets.“
Nokia and SURF, the organization for IT in Dutch education and research, have successfully reached a single carrier 800Gb/s optical transmission over SURF’s existing cross-border, multi-vendor research and education network infrastructure.
Nokia and Vodafone are collaborating to test the viability of L4S technology over passive optical networks (PON).
The GSMA believes that critical reform of European laws is necessary to position the region as a technology frontrunner by 2030.
