What is C-band used for?

According to wireless testing firm Rohde and Schwarz, the C-band is all frequencies between 4 and 8GHz . When US wireless geeks talk about C-band, though, they’re talking about 3.7 to 4.2GHz—and specifically, in this case, the range from 3.7 to 3.98GHz.

About that spectrum: T-Mobile has 160 MHz on average in the 2.5 GHz layer. It picked up 40 MHz in the C-band auction, but that’s in the second tranche, which won’t be available until 2023 . … Leading up to the availability of that C-band spectrum, T-Mobile can convert more of that Sprint PCS spectrum to 5G.

The terms C-band and “Mid-band” are often used interchangeably . It is more accurate to describe the C-band frequency range as a component of the larger 3.3 – 4.2 GHz mid-band spectrum. Mid-band resides within frequency range 1 (FR1), located squarely between low-band FR1 and the “millimeter wave” (FR2) RF spectrum.

The C band is used for many satellite communications transmissions, some Wi-Fi devices, some cordless telephones as well as some surveillance and weather radar systems .
