5G Sub 6

Globally, the C-band refers to frequencies between 4 and 8GHz. In the U.S., however, carriers don’t have access to all those frequencies, and right now, they’re only using frequencies between 3.7 and 3.98GHz. That means that while mid-band is a subset of Sub-6, C-band in the U.S. is a subset of mid-band frequencies .31 Oca 2022

mmWave refers to higher frequency radio bands ranging from 24GHz to 40GHz, and Sub-6GHz refers to mid and low-frequency bands under 6GHz .10 May 2021

In many countries, n78 (3500 MHz), or commonly referred to as the 3.5 GHz 5G band, or C-band 5G , is the most commonly tested and deployed 5G frequency. The n78 band’s popularity is due to its relatively common availability, compared to lower cellular spectrum (below 2700MHz) already widely in use by 3G and 4G networks.
