This means that some of the fear surrounding 5G is not unfounded. T and perhaps more efficiently and securely. If you look at most of the networks currently rolling out globally, they are mostly using sub-6GHz networks. That doesn’t mean they can’t or won’t use higher frequencies, called “mmWave.” We’ll talk about that later. 5G NSA and SA Part of the 3GPP Release 15 specification allows for the creation of NSA and SA network architectures What does this mean? First, it has nothing to do with the US National Security Agency, but it has a lot to do with the rapid deployment of 5G.
Many 3GPP members have been lobbying for a faster 5G gansu phone data deployment in 2019 instead of 2020, which has led to a two-step process for launching 5G networks. The first step is known as NSA, or non-standard, where mobile carriers like Verizon, AT&T, Sprint, and T-Mobile can use most of their 4G infrastructure to run their 5G networks. While this means less money for carriers to spend initially building out 5G networks, it also means that early 5G devices will have to connect to both 4G and 5G simultaneously.
This shouldn’t be surprising, given that any new cellular technology will initially have limited coverage and will have to rely heavily on older ones for a long time to gain coverage. This also means that mobile operators can combine their 4G and 5G to achieve even faster speeds, with technologies like EN-DC. EN-DC is an industry technical acronym that stands for E-UTRAN New Radio - Dual Connectivity (E-UTRAN is the technical term for 4G LTE).
