What does 5gsa mean?

5GSA refers to the 5G independent network group, that is, the 5G private network mode.

SA is independent, which means independent network. In the 5GSA architecture, both the 5G core network and the 5G radio access network (RAN) are brand-new and no longer need to rely on the 4G network. Compared with 5GSA (non-independent architecture) which relies on the existing 4G infrastructure, 5GSA can provide higher network capacity, faster speed and lower latency.

5GSA has three application scenarios: Enhanced Mobile Broadband (EMMB), High Reliability and Low Delay (URLLC) and Mass Connection (MMTC). At the same time, 5GSA also has new 5G features such as network slicing, edge computing and cloud network convergence. These features enable 5GSA to provide higher network performance and better user experience.

In a word, 5GSA is a brand-new 5G network architecture. Compared with 5GNSA, it can provide higher network performance and better user experience.

5G network type

1, NSA mode. NSA mode, also called "dependent networking mode", is a kind of 5G based on the original 4G network, so many people call it "fake 5G". At the beginning of the transition from 4G to 5G, in order to speed up the deployment of 5G, many operators often choose to reduce the cost of infrastructure and increase the network speed on the basis of 4G. Therefore, the transmission rate of NSA mode is only a little faster than that of 4G, so it can't be called a real "5G".

2. The SA .SA mode, also known as the "independent networking mode", refers to the service provider's independent construction of the real 5G base station, and the overall core network is built by 5G, which is a real 5G. When users connect to the 5G network through different terminal devices, they can feel different rates. At present, the infrastructure of 5G is not available all over the country, and the coverage rate is still relatively low. Some big cities have invested.
