Ericsson joins hands with MediaTek to enhance 5G user experience with Dual Connectivity technology

Ericsson and MediaTek have recently continued to make new technological breakthroughs in the field of 5G Standalone (5G SA) networking. Not long ago, MediaTek proved that dual connectivity technology (that is, combining the large coverage of the frequency band below 6GHz with the higher data rate of millimeter-wave on commercial hardware and chipsets) can increase 5G quality with higher speed and lower latency experience.

MediaTek has made a new breakthrough by aggregating 800MHz high-frequency spectrum and 60MHz mid-frequency spectrum, enabling the maximum speed of a single user device to reach 5.1Gbps. This is the first time in the 5G SA mode, the mid-frequency band has been aggregated to test millimeter waves.

It is understood that this 5G dual connection or New Radio (NR) DC test was carried out in a millimeter-wave laboratory, and the signal was sent to a device equipped with a MediaTek M80 5G modem through a wireless network. The demo successfully showed that because the connection is located in both millimeter-wave and mid-band spectrum, millimeter waves can be used with confidence in the new 5G SA architecture, which will make the uplink and downlink data rates of 5G SA higher than current deployments.

Signal transmission and high peak rate in Ericsson 5G core network, 5G wireless access network (Ericsson wireless system), and user equipment (such as MediaTek M80 modem) are the keys to achieving NR DC. NR DC will also provide support for the development of high-performance, delay-sensitive applications for individuals and enterprises, helping to lay the foundation for innovative use cases for mobile broadband and fixed wireless access (FWA) such as games and immersive media. In addition, the report shows that Ericsson will release the commercial NR DC function in the third business quarter of 2021.
