What frequency range does Extremely High Frequency (EHF) cover?

Extremely High Frequency (EHF) is defined as the frequency range from 30 to 300 gigahertz (GHz). This range is part of the electromagnetic spectrum and is primarily used for advanced communication technologies, radar systems, and satellite communications. The characteristics of EHF allow it to support a wide array of applications, including high data rate transmission and secure communication links, making it integral to modern wireless communication systems.

In contrast, the other frequency ranges mentioned do not fall under the classification of EHF. The range of 3 to 30 GHz corresponds to the Super High Frequency (SHF), while 300 to 3,000 MHz falls under the Ultra High Frequency (UHF), and the 3 to 30 MHz range is associated with Very Low Frequency (VLF) communications. Understanding these classifications helps in recognizing the applications and limitations associated with each frequency range within the electromagnetic spectrum.
