Over the past three years, China has also built the world's largest 5G network, with the total number of base stations exceeding 2 million in October, reaching the annual target ahead of schedule. However, 5G construction cannot be achieved overnight. Millimeter wave 5G is still in its early stage, and Qualcomm recently achieved a breakthrough in 5G millimeter wave in China.
According to Qualcomm, it has completed a series of 5G independent networking (FR2-only) tests in China,The tests were conducted using Snapdragon X65 5G modems and RF test terminals,It is respectively connected with network infrastructure equipment of leading system network manufacturers such as ZTE, Nokia-Bell Shanghai and Chinatrust Mobile.
In the test,When using DDDSU frame structure, the 5G downlink peak rate of more than 7.1Gbps is achieved.When using DSUUU frame structure, the uplink peak rate is more than 2.1Gbps, and the test delay is as low as 3.6ms.
All tests and technical validation were carried out under the guidance of the IMT-2020 (5G) propulsion group.
The test results show that without the use of LTE or Sub-6GHz spectrum anchor, 5G millimeter wave independent networking mode (FR2-only) brings higher speed and lower delay than Sub-6GHz band, thus making 5G network deployment more flexible and meeting the demand for larger network capacity.
