Telecom infrastructure major Huawei announced that peak cell throughput has exceeded 20 Gbit/s to achieve a breakthrough in the C-Band test.

This test procedure is an important part of the China 5G Technology Research and Development (R&D) Trial which is organized by the IMT-2020 (5G).

During the C-Band test, Huawei adopted 5G New Radio, Massive MIMO, Polar code, and other technologies using the entire 200MHz bandwidth on the 4.9 GHz carrier to achieve the seamless wide-area coverage scenario.

Both the 3.5 GHz carrier and 4.9 GHz carrier tests are important components of technology solution verification of China’s 5G R&D trial.

Early this year, Huawei said its 5G tests in three typical scenarios on 3.5 GHz carriers met performance required by the International Telecommunication Union (ITU). As a supplement to the test on the 3.5 GHz carrier, the test on the 4.9 GHz carrier makes the C-Band test more complete.

Huawei, one of the core members in the IMT-2020 5G Promotion Group, has deployed thirty 5G terminals over seven 5G sites in Huairou District, Beijing, supporting large-scale field tests.

When phase one of the R&D trial on 5G technologies was completed, Huawei announced the launch of a 5G phase two trial in August, 2016.
