Ericsson and MediaTek achieved 565 Mbps performance by combining two Ericsson software features – uplink single user multiple input multiple output (SU-MIMO) and Uplink Carrier Aggregation – on MediaTek T830 CPE platform with three transmit (3Tx) antennas. The test focused on optimizations for fixed wireless access applications (FWA).
For this demo, a 2.1GHz FDD (frequency division duplex) band was combined with a 3.5GHz TDD (time division duplex) band.
Ericsson said FWA would benefit greatly from combining Uplink SU-MIMO with Uplink Carrier Aggregation in FR1 spectrum, where FR1 stands for Frequency Range 1, the most commonly deployed 5G spectrum globally.
Dr Sibel Tombaz, Head of Product Line 5G RAN, Ericsson, says: “This latest milestone with MediaTek proves that we at Ericsson are continuously innovating and leveraging new technologies to deliver the best possible 5G user experience. With this latest solution offering, fixed wireless access subscribers, consumers and businesses alike, can benefit from higher upload speeds for data-heavy applications such as cloud gaming and extended reality. We are offering high-performing solutions for the evolving fixed wireless access market.”
HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek, says: “Enhancing uplink performance is an essential advantage for 5G FWA devices used by businesses, and this technology breakthrough will further extend the advantage of 5G CPE versus line-based broadband services.
Ericsson predicts FWA connections will reach 300 million in 2028 from 107 million in 2022. By 2028, 5G is estimated to account for almost 80 percent of all FWA connections.
