5g mobile phones can be seen from the network type as nsa and sa. Operation method: 1. Open the phone settings and click "Dual SIM and Mobile Network"; 2. After entering "Dual SIM and Mobile Network", click "Advanced Settings"; 3. In the "Advanced Settings" interface, find "5G Network Type" ” to view.
#The operating environment of this tutorial: MIUI 12 system, Xiaomi 11 mobile phone.
Nowadays, 5G mobile phones are becoming more and more popular. Basically, you can buy a 5G mobile phone at a price of around 2,000. However, many people think that turning on the 5G switch in the settings will enable the 5G network. In fact, it may be In the NSA mode network of 5G non-independent networking, there is still a certain difference in speed between NSA and SA mode. So how can you tell if a 5g mobile phone is NSA or SA?
5g mobile phones can tell from the network type that they are nsa and sa.
The specific steps are as follows:
1. Open the phone settings and click Dual SIM and mobile network
2. Enter Dual SIM and Mobile Network, click Advanced Settings
3. Enter Advanced Settings, find the 5G network type to view
The meaning of NSA and SA
5G has two networking methods, one is non-standalone (NSA) and the other is independent Networking (Standalone, SA). NSA refers to the joint networking of 5G and 4G LTE, which means that a 5G network is built on the basis of existing 4G equipment.
NSA refers to the joint networking of 5G and 4G LTE, which means that 5G networks are deployed based on existing 4G equipment. Under 5GNSA networking mode, operators can use 4G, 5G Sharing the core network saves network investment, but the disadvantage is that it cannot support the core new features of 5G such as low latency.
Moreover, the mobile phone needs to be connected to 4G and 5G networks at the same time under the NSA network, and the power consumption is higher than that under the SA network. In order to save money, some operators will use the NSA method in the early stages of 5G network construction, so many netizens also ridiculed that NSA is "fake 5G".
The purpose of NSA is to enable consumers to use 5G equipment faster. At this stage, whether it is the speed of base station construction, the maturity of mobile phones, the continuity of signal coverage and positioning, or the consideration of international roaming and not changing cards To meet the demand for 5G services without changing numbers, deploying NSA first is the consensus of operators and the industry and is an objective choice.
At the same time, users cannot experience the low-latency features brought by SA, and the uplink bandwidth of NSA is far lower than that of SA. Many performance defects of NSA will hinder the development of new services, such as Smart manufacturing, 5G medical emergency, VR live broadcast, etc. that are very sensitive to uplink bandwidth and delay.
There are three main differences between NSA and SA:
1. NSA does not have a 5G core network, while SA has a 5G core network. This is a key difference.
2. Under NSA networking, 5G and 4G interoperate at the access network level, and the interconnection is complicated; under SA networking, the 5G network is independent of the 4G network, and 5G and 4G only interoperate at the core network level. , simple interconnection.
3. Under NSA networking, the terminal is dual-connected to LTE and NR wireless access technologies; under SA networking, the terminal is only connected to NR wireless access technology.
