ZTE Corporation, an international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, claims to have completed the world's first-millimetre wave (mmWave) over-the-air (OTA) performance test for 5G. This was an end-to-end test based on a multi-probe darkroom test system pioneered by China Academy of Information and Communications Technology (CAICT) and China Mobile Research Institute. ZTE's mmWave base station system was used to fully verify the test specifications of the mmWave OTA system, and also achieved excellent end-to-end performance using different complex wireless channels, marking a major step forward in the commercial use of 5G mmWave systems.
Jointly conducted by CAICT and ZTE, the 26 GHz mmWave base station test has verified the basic performance items in NSA networks. The test items at different NLOS (non-line-of-sight)/LOS (line-of-sight) channel models include access performance, user peak rate, fixed bit rate test, AMC (Adaptive Modulation and Coding) test, high-speed performance test, and beam management test.
The test has adopted ZTE's full range of end-to-end solutions, including a 5G mmWave high-performance base station, 5G core network equipment and brand-new mmWave test terminals. The experimental data shows that ZTE’s mmWave system with 200 MHz bandwidth and commercial network configuration can provide a single user with a peak rate of up to 1.15Gbps. In the deteriorating high-speed NLOS scenarios of 120 Km/h and 160 Km/h, ZTE’s mmWave system can still provide a peak rate of 822Mbps and 723Mbps respectively, demonstrating the superior end-to-end performance of ZTE’s mmWave system.
By virtue of its experience in the performance verification of wireless systems in mainstream frequency bands, ZTE can provide operators with mature, end-to-end 5G products and solutions. Moving forward, the company will continuously support and cooperate with the IMT-2020 (5G) promotion group to prepare for the commercial use of mmWave systems and help operators achieve 5G commercial success.
