Today, Huawei Weibo officially announced that the Huawei Mate 20 X 5G obtained China’s first 5G terminal telecom equipment network license. According to the official introduction, this is a 5G dual-mode smartphone that supports SA/NSA simultaneously.
Bruce Lee, vice president of Huawei’s smartphone product line, stressed that only Huawei can provide SA/NSA 5G dual-mode phones.
SA and NSA respectively represent 5G independent networking and non-independent networking. In the 5G NSA networking mode, operators can share the core network with 4G and 5G, saving network investment. But the disadvantage is that it cannot support 5G’s new features such as low latency.

Moreover, the smartphone needs to connect 4G and 5G networks at the same time under the NSA network. Thus, the power consumption will be higher than that of the SA network. In order to save money, some operators will adopt the NSA mode in the initial stage of 5G network construction. But SA is the final evolution direction of 5G.
We know that the Huawei Mate 20 X 5G version is equipped with a 5G multi-mode terminal chip Baron 5000, which is the world’s first single-core multi-mode 5G baseband, based on 7nm process technology. It not only supports 5G SA independent and NSA fee independent networking but also supports 4G, 3G, and 2G networks.
According to the official introduction, Baron 5000 is the first to achieve the industry’s benchmark 5G peak download rate. Say, it has achieved 4.6Gbps in the sub-6GHz (low-frequency band, 5G main frequency band) band. And in the millimeter wave (high-frequency band, 5G extended band), it reached 6.5Gbps, which is 10 times the experience rate of 4G LTE.
