What is 5.5G? Some models equipped with Snapdragon 8 Gen3 and Dimensity 9300 processors can still support 5.5G without the N79 band? Let's talk about it today!
First of all, let's briefly talk about what 5.5G is, and what is the difference between it and traditional 5G?
5.5G network, also known as 5G-A, is a transition product in the development process from 5G to 6G, but its speed is 10 times faster than the traditional 5G, and the stability and latency of the network are better.
Then let's talk about the N79 frequency band, N79 belongs to the 5G frequency band used by China Mobile, which is medium and high frequency, characterized by high bandwidth, but small transmission range and poor penetration, so it is mainly deployed in occasions that require high density and high traffic, such as railway stations, stadiums, hot crowd areas, etc.
Most areas are deployed in the N41 frequency band, so if the mobile phone does not support the N79 frequency band, it will affect the 5G network speed of mobile card users, but China Unicom and Telecom users will have no impact.
Then some people are probably going to ask, how big is the scope of this impact?
For example, even in densely populated Beijing, the N41 band is still used in most areas, while the coverage area of the N79 band is very targeted.
So, is there a necessary connection between whether the mobile phone supports 5.5G network and N79?
5.5G is the use of the aggregate carrier of the 5G frequency band to achieve higher bandwidth, you can think of it as bundling the bandwidth of multiple frequency bands, so the speed is faster.
The 5.5G bundled frequency band combinations of each company are N41+N28A, which are available to the three major operators, and China Mobile has three more N79 combinations than other operators.
Therefore, some models equipped with Snapdragon 8 Gen3 and Dimensity 9300 processors, especially those with relatively large sales, such as Xiaomi 14, vivo X100, iQOO12, realme realme GT5 Pro, although there is no N79 in the frequency band, as long as there is N41 and N28A, it can theoretically support the 5.5G network of the three major operators.
For example, the Honor Magic6 series has been confirmed to support 5.5G, including the Magic6 standard version without the N79 frequency band.
Seeing this, some people may say, then this N79 band is useless?
Of course not, the 5.5G carrier combination that can be supported by mobile phones with the N79 band is undoubtedly the most complete.
But the premise is that you have to be a distinguished mobile user, and at the same time you have to be a distinguished top flagship mobile phone user, and you have to be in the first-tier cities of railway stations, stadiums and other key coverage occasions.
Therefore, there is no need to worry about the lack of the N79 band in mobile phones, which is not the only criterion for deciding whether to support 5.5G or not.
