Which frequency range is classified as EHF?

The classification of frequency ranges is based on the electromagnetic spectrum, where different ranges are designated for specific applications and characteristics. The Extremely High Frequency (EHF) range is defined as encompassing frequencies from 30 GHz to 300 GHz. This frequency range is utilized for various advanced communications systems, including satellite communications, radar, and some forms of wireless data transmission.

Understanding this classification is crucial as EHF frequencies exhibit certain properties that distinguish them from lower frequencies. For example, they can provide higher data rates and increased bandwidth but may also face challenges such as higher atmospheric attenuation and limited range capabilities.

Recognizing the context of the other frequency ranges reinforces the understanding of EHF. The range of 30-300 KHz is classified as Very Low Frequency (VLF), 3-30 GHz falls under the Super High Frequency (SHF) category, and 300-3000 MHz defines the Ultra High Frequency (UHF) band. Each of these classifications serves different technical purposes and applications within the field of communications.
