Ericsson and MediaTek have set a new 5G uplink speed record of 440 Mbps in low-band and mid-band spectrum using Uplink Carrier Aggregation. That uplink speed was achieved in an Ericsson lab. The test was performed with Ericsson’s Radio Access Network (RAN) Compute Baseband 6648 and a mobile device using a MediaTek Dimensity 9200 flagship 5G smartphone chipset.
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. The fast 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 440 Mbps 5G upload speed achieved in the lab compares to an average of 26.78 Mbps outdoors and 22.98 Mbps indoors, as per a Cellsmart survey.
Sibel Tombaz, Head of Product Line 5G RAN, Ericsson, said: ”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. The 440 Mbps upload speed achieved by Ericsson and MediaTek will help make that difference. We are also continuously designing innovative solutions for optimizing 5G networks so our customers can make the best use of their spectrum assets.”
Service providers are seeking innovative ways of boosting capacity while using existing spectrum efficiently to meet growing demands for wireless data and applications. This is where carrier aggregation comes in, optimizing the service provider’s spectrum assets to bring to users better coverage, increased capacity, and higher data speeds.
HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek, said: “The successful result of combining Ericsson’s state-of-the-art 5G Baseband and MediaTek’s flagship smartphone chip has achieved another 5G industry milestone, and paves the way for superior mobile experiences to benefit users every day.” Uplink speed is becoming more crucial with the expected uptake of
gaming, XR, and video-based apps. For example, as AR devices gain popularity with larger augmentation objects, rendering becomes more demanding. This increases the demand on networks to deliver higher throughput and lower latency.

Earlier this year, AT&T boasted that it had completed what was believed to be the first 5G standalone (SA) uplink 2-carrier aggregation data connection in the U.S.
The connection was made at its Redmond, Washington, lab, where they achieved upload speeds of over 120 Mbps with a combination of 850 MHz and 3.7 GHz spectrum.
In May, T-Mobile reported reaching uplink speeds over 200 Mbps in a 5G data call using uplink CA; in that case, they used T-Mobile’s live commercial 5G SA network as opposed to a lab environment. T-Mobile used 2.5 GHz and 1.9 GHz bands.
