C-band is all frequencies of the electromagnetic spectrum measured between 4 Ghz and 8 Ghz ; but the sweet spot of C-band that Verizon and AT&T are buying up is between 3.7 to 3.98GHz. That is used by satellite transmissions, wifi devices, and weather.

Sub-6 5G will have better coverage than millimeter-wave but isn’t as widely available, making the potential top speed lower. Currently, AT&T, T-Mobile, Verizon, and U.S. Cellular utilize sub-6 5G in the United States. The FCC says that low-band frequencies are 600Mhz, 800Mhz, and 900Mhz.

Radio frequency bands below 6 GHz (6,000 MHz) . Prior to 2019, all radio frequency bands used for mobile phones were below 6 GHz. 5G introduced much higher-frequency mmWave bands, and thus the need for the term “sub-6 GHz” to distinguish existing bands from mmWave.
