1. NSA refers to Non-Standalone networking mode.
< br >
It is networked by integrating 5G base stations and 4G base stations. This networking mode has small investment and fast deployment, and can quickly promote the coverage of 5G network. Therefore, NSA is also the leading networking mode of mainstream commercial 5G in most countries.

2. SA stands for Standalone networking mode.
< br >
Through the construction of an independent 5G base station network, it requires a completely new 5G core network to be put into use. This networking mode requires more investment and takes longer time to achieve basic coverage. Therefore, the SA networking mode will be gradually promoted in the process of NSA 5G popularization.
< br >
At present, domestic operators have started NSA mode 5G services, and SA mode is in the stage of discussion and promotion. According to the development trend of 5G, almost all countries that currently deploy 5G are NSA first, on this basis, gradually transition to dual-mode networking, and finally achieve SA. For consumers, the single mode or dual mode 5G terminals on the market can achieve 5G networking, so there is no saying that \"NSA is fake 5G\".
Different routers may have different working modes. Taking TP-Link routers as an example, it is recommended to select 11a\/n\/ac mixed mode and keep the default 161 on WiFi 5G channel, because if the channel is too low, some mobile phones do not support access. The details are as follows:
1. Generally, routers will provide multiple transmission protocol modes for choice. Taking TP-Link as an example, it is recommended to set the mode to 11a\/n\/ac mixed, which can ensure that the router broadcasts dual-frequency signals of 2.4GHz and 5GHz, ensuring the compatibility of device connection;
2, in the setting also need to select the channel, it is recommended to keep the default 161,161 is China's civil channel, and 36-64 channel is a late open application, some products do not support, if set these channels equipment may not be able to search for WiFi signals.
5G mobile phone users can choose three network modes:
1. Free choice mode: The general network choice is 4G network;
2.SA mode: The network preferentially resides on the 5G network for Internet access services.
3.SA NSA mode: The network also preferentially resides in 5G for business;
