What is C-band and what does it mean ?

For 5G to deliver a better experience than 4G, it needs a wide, dedicated channel, preferably 50 MHz or more. That's where C-band comes in: the frequency that can save 5G in the United States.

He came. You see. The planes did not fall from the sky. AT&T and Verizon recently rolled out their c band 5G networks after months of wrangling with airlines and the FAA. In logging, so far, we have not seen any major aviation problems or threats to aviation safety. After two years of AT&T and Verizon's "national 5G" network looking like 4G, C-band may finally increase speed. But what is C-band and what does it mean for 5G? Do you need a C-band phone? Is C-band the new frequency? Should we fear group C? We can explain. Satellite recovery

According to the radio research company Rohde and Schwarz, C-band covers all frequencies between 4 and 8 GHz. However, when American wireless geeks talk about C-band, they're talking about 3.7 to 4.2 GHz - and more, in this case, the 3.7 to 3.98 GHz range.

There is also another range of radio waves involved, from 3.45 to 3.55 GHz. No one really decided what to call them: they were "3.45", "DoD" (the military used them), or even "Andromeda". But they have a lot to do with the C.-band spectrum, so we include them in this description.
