The 3 centimeter or 10 GHz band is a portion of the SHF radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. The amateur radio band is between GHz and GHz, and the amateur satellite band is between GHz and GHz. The allocations are the same in all three ITU regions. “GHz” stands for gigahertz. “Giga” equals one billion or 10^9 in the SI measurement system. One GHz equals one billion cycles per second. Thus, GHz is a unit of frequency. GHz is used to refer to radio frequencies, sound frequencies, and computer processors at higher frequencies. In computers, GHz refers to the clock speed of the 5/5(2).

5G will employ low- ( GHz - GHz), mid- ( – 24 GHz), and high-band frequencies (24 GHz and higher). In the U.S., the Federal Communications Commission (FCC) has allocated “low-band” spectrum at GHz (e.g., MHz), “ mid-band” spectrum in the GHz range, and 11 GHz of “high-band” frequencies including licensed spectrum from GHz and . Terahertz (THz) radiation with frequencies between GHz and 30 THz has developed into an important tool of science and technology, with numerous applications in materials characterization, imaging, sensor technologies, and telecommunications.
