Ericsson announced a new upload speed record with 5G on mmWave spectrum. In a test of four-component carrier uplink aggregation with MediaTek, the company achieved a peak throughput rate of 495 Mbps. This included 425 Mbps on 5G New Radio plus 70 Mbps in LTE.
The demo performed in June used pre-commercial software on a device containing a MediaTek M80 5G chipset. The lab test used Ericsson RAN Compute baseband 6648 with the AIR 5331 millimeter wave radio. Four carriers of 100 MHz each in the 39 GHz band were used for non-standalone 5G, along with 20 MHz in the 1,900 MHz band for LTE.
Ericsson said the test of uplink carrier aggregation is the first of its kind, as the industry previously focused more on boosting download speeds. The increased adoption in the past year of home working and schooling has driven the use of applications like videoconferencing that require also fast upload speeds.
