Ericsson, MediaTek claim upload speed record of 440 Mbps

Ericsson and MediaTek say they set a new 5G upload record of 440 Mbps using uplink carrier aggregation (CA). 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. Specifically, the CA combination involved here was 50 MHz FDD 2.1 GHz and 100 MHz of TDD C-band, or 3.7 GHz. Ericsson said that by aggregating these two bands, communications service providers can considerably increase their uplink speeds, resulting in better network performance and user experience. Uplink speed is becoming more critical with the expected uptake of gaming, XR and video-based apps. By way of example, Ericsson notes that as AR devices gain popularity with larger augmentation objects, rendering becomes more demanding, thereby increasing the demand on networks to deliver higher throughput and lower latency.
