What is C-Band?

C-Band refers to a mid-band spectrum ranging from 3.3 GHz to 4.2 GHz, widely used for 5G networks, satellite communications, and radar systems. In the U.S., mobile carriers like Verizon, AT&T, and T-Mobile use the 3.7 GHz to 3.98 GHz portion of the C-Band to provide a balance between coverage and speed, offering faster data rates than low-band spectrum while providing better range and building penetration than mmWave. C-Band is considered a key component of 5G deployment, enabling faster connectivity in cities and suburbs while supporting high-demand applications like streaming, gaming, and IoT devices.
