Definition

Noun: - The entire range of electromagnetic frequencies used for communications: The "radio spectrum" refers to the complete span of radio frequencies, which is a specific portion of the broader electromagnetic spectrum. This range of frequencies is allocated for various communication technologies.

Usage

The term "radio spectrum" is used to discuss the allocation, management, and technical properties of the frequencies used for wireless communication. - It is a finite natural resource managed by governmental agencies. - Different bands within the spectrum are designated for specific services like broadcasting, mobile phones, or satellite links.

Examples

• Noun:
  • The government auctioned licenses for a new part of the radio spectrum for 5G networks.
