5G phones can be seen as nsa and sa from the network type.
Open your phone's settings, click on Dual SIM & Mobile Networks, go to Dual SIM & Mobile Networks, click on Advanced Settings, go to Advanced Settings, find the 5G network type to see if it's SA or NSA.
There are three main differences between NSA and SA:
1, NSA does not have a 5G core network, SA has a 5G core network, which is a key difference.
2, in the NSA network, 5G and 4G in the access network level interoperability, interconnection is complex; in the SA network, 5G network is independent of the 4G network, 5G and 4G only in the core network level interoperability, interconnection is simple.
3. Under NSA networking, terminals are dual-connected to both LTE and NR radio access technologies; under SA networking, terminals are connected to only one radio access technology, NR.
NSA and SA meaning
5G has two kinds of networking methods, one is non-standalone (Non-Standalone, NSA), the other is standalone (Standalone, SA). NSA means it is the joint networking of 5G and 4GLTE. of joint networking, which means a 5G network based on existing 4G equipment.
NSA refers to the joint networking of 5G and 4GLTE, that is to say, on the basis of the existing 4G equipment for the deployment of 5G networks. In the 5GNSA networking mode, operators can 4G, 5G **** with the core network, saving network investment, but the disadvantage is that it can not support low latency and other new features of the most core 5G.
And cell phones need to be connected to both 4G and 5G networks under NSA networks, and power consumption is higher than under SA networks. In order to save money, some operators will use NSA in the early stage of 5G network construction, so many users also said 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, cell phone maturity, signal coverage and positioning continuity, or to consider the demand for international roaming and not change the card not change the number that is to use the 5G service, the first deployment of NSA is the operator and the industry's *** knowledge is also an objective choice.
Then at the same time, users can not experience the low-latency characteristics of SA, and the uplink bandwidth of NSA is much lower than that of SA, and many of the performance deficiencies of NSA will impede the development of new services, such as smart manufacturing, 5G medical emergency and VR live broadcasting, which are very sensitive to uplink bandwidth and latency.
