Ericsson announced a collaboration with MediaTek to achieve a new 5G network uplink transmission speed of 565Mbps, breaking the previous record of 440Mbps.
Increasing uplink transmission speeds will enhance the user experience of FWA (Fixed Wireless Access), which replaces traditional wired connections with wireless transmission. It will also benefit applications such as cloud-based streaming games and virtual reality, which require higher upload response speeds.
The collaborative test was conducted on MediaTek's T830 5G connectivity chip, used in high-end CPE (Customer Premise Equipment). Combined with Ericsson's software-based uplink Single User Multipath (SU-MIMO) technology and uplink carrier aggregation, the three transmit antennas achieved uplink speeds of up to 565Mbps.
In addition, the test was conducted on the 2.1GHz frequency division duplex (FDD) band and the 3.5GHz time division duplex (TDD) band. Both are the most commonly deployed 5G network frequency bands by global telecom operators and the primary 5G network frequency bands deployed by Taiwanese telecom operators. Therefore, they are more conducive to promoting the wireless access application market in Taiwan.
Sibel Tombaz, Head of Product Line 5G RAN at Ericsson, says: "This new milestone demonstrates Ericsson's continued investment in innovation and leveraging new technologies to provide users with the best 5G experience. With this latest solution, both enterprise and consumer FWA users can benefit from higher uplink speeds, which is particularly beneficial for data-intensive applications such as cloud gaming and augmented reality. We will continue to develop high-performance solutions for the evolving FWA market."
Huang Heqi, General Manager of MediaTek's Wireless Communication Systems Development Unit, said: "Improving uplink performance is critical for enterprise-grade 5G FWA equipment. This technological breakthrough will further expand the advantages of 5G CPE. MediaTek and Ericsson have collaborated to overcome technical limitations and further improve network performance and efficiency. This not only opens up new possibilities for telecom service providers and consumers to enjoy faster and more reliable 5G internet services, but also establishes both parties' technological leadership in the market."
