Qualcomm Technologies and ZTE last week announced that, to support the testing needs of the IMT-2020 (5G) promotion group for 200MHz carrier bandwidth over 5G mmWave, the companies successfully showcased features required in anticipation of 5G mmWave rollouts in China.
The tests were completed using a smartphone form-factor test device powered by the flagship Snapdragon X65 Modem-RF System, and ZTE mmWave AAU network infrastructure equipment. This marks the first connection in China using 5G NR standalone Dual-Connectivity (NR-DC, or FR1+FR2 DC) with one 200 MHz carriers 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.
