Qualcomm and ZTE Complete Snapdragon X65 Baseband mmWave Test in China

Qualcomm and ZTE Complete Snapdragon X65 Baseband mmWave Test

Recently, Qualcomm and ZTE achieved a new milestone of 5G millimeter-wave for the cooperation and support of the IMT-2020 (5G) Promotion Group developed to support the 200MHz carrier bandwidth of 5G millimeter-wave testing and deployment needs.

It is reported that Qualcomm and ZTE used smartphone form factor test terminals equipped with the flagship Snapdragon X65 and network infrastructure equipment such as ZTE’s millimeter-wave AAU to complete the test, demonstrating significant progress towards commercial 5G millimeter-wave in China.

This marks the first connection in China using 5G NR standalone Dual-Connectivity (NR-DC, or FR1+FR2 DC) with one 200 MHz carrier in the 26 GHz (n258) mmWave band, along with one 100 MHz carrier in the 3.5 GHz (n78) band, achieving a peak downlink speed of over 2.43 Gbps using a single device. In the tests, the companies also achieved a peak downlink speed of over 5 Gbps using a single device employing carrier aggregation with four 200MHz carriers in the 26 GHz (n258) mmWave band and successfully tested two 200 MHz mmWave carriers on the uplink. The use of standalone (SA) that uses a 5G Core (5GC) network allows for capabilities such as network slicing and lower latency.


According to previous news, the Snapdragon 898 (SM8450) flagship chip to be released at the end of the year will have the Snapdragon X65 baseband built-in, as Qualcomm had already revealed at the Snapdragon 888 Plus launch.

As previously reported by IT House, the Qualcomm Snapdragon X65 5G modem was formally released in early 2021 and is the world’s first chip to support 10Gbps 5G rates, manufactured using a 4nm process. Qualcomm previously said that the X65 chip is capable of simultaneous Sub-6GHz and high-band millimeter-wave connectivity, with dual-band concurrent data transmission. The completion of the 5G millimeter-wave test by Qualcomm and ZTE signals that this communication service is expected to be launched in mainland China, enabling faster connection rates.

Snapdragon 898 will not only have a built-in X65 baseband to achieve higher 5G connectivity, but will also have another surge in performance, with a triple-cluster CPU design, including a mega-core frequency of 3.09GHz, a large core frequency of 2.4GHz, and a small core frequency of 1.8GHz, of which the large 3.09GHz core will have a new generation of Cortex-X2 design.
