Ericsson has partnered with Finnish communications service provider Elisa and chipset vendor Qualcomm Technologies, Inc. to demonstrate high uplink speeds in commercial 5G standalone (SA) networks, enabling Elisa subscribers to Deliver a seamless user experience.
The three partners used uplink carrier aggregation to achieve upload speeds of 230 Mbps on live 5G networks. This test combined the 25MHz 2.6 GHz FDD (frequency division duplex) band with the 100MHz 3.5 GHz TDD (time division duplex) band on a mobile test device equipped with a Snapdragon® X75 5G modem RF system.
Ericsson’s uplink carrier aggregation software combines mid-band FDD and mid-band TDD within Frequency Range 1 (FR1), increasing speeds for applications such as live streaming, broadcasting, cloud gaming, augmented reality, and video-based usage. Enables uplink-intensive applications. Case.
More and more consumer applications are making heavy use of uplinks
The amount of data traffic generated on uplinks is currently increasing, highlighting the need for new network capabilities to increase uplink speeds and capacity and provide a seamless 5G user experience. . For example, concertgoers are recording and streaming live video on their social media accounts. Fast uplink speeds allow you to share your most exciting moments with friends and family in real-time without worrying about delays, congestion, or poor network quality.
Ericsson has a robust portfolio of software features to enhance uplinks, and FR1 Uplink Carrier Aggregation, a feature introduced in this demo with Elisa and Qualcomm, will be commercially available in Q4 2023 became.
