These years there are a lot of science on NSA and SA networking methods, simply put, both ways are 5G, NSA is non-independent network, technology mature, can be widely covered, SA is independent network, to achieve basic coverage takes time, but SA is obviously the final choice of 5G, more technical advantages, but also need to do more investment. October 5, one of the mainstream suppliers of communications equipment Datang Mobile announced that it has successfully completed the SA terminal chip functional interoperability test and ZUC performance test with Huawei Heath and MediaTek chips.
It is reported that this SA interoperability test covers the physical layer, RRC layer, NAS layer function testing, including business hosting, network slice, 4G/5G interoperability, EPS down and other tests, Datang Mobile said successfully completed all the test content, fully verified that its 5G commercial products and the current mainstream chip has good interoperability, for the next 5G SA large-scale commercial deployment has laid a good foundation.
In zuC performance testing, the up/down data rate and delay in the MU-MIMO high-capacity scenario were successfully completed, and the up/down data rate and delay in the SU-MIMO scenario were completed with the instrument, and the performance test results reached the expected target. Datang Mobile has developed 2.6/3.5/4.9GHz multi-band indoor and outdoor 5G base station products, supporting SA/NSA networking, and fully supporting 5G commercial.
Data show that China Xinke Group’s Datang Mobile Communications Equipment Co., Ltd., is the proposer of TD-SCDMA and TD-LTE, the owner of the core intellectual property rights, in the past, co-partners accounted for 30% of China’s TD-SCDMA equipment market share, but also one of the mainstream suppliers of TD system equipment.
