Definition

Noun: A specific, continuous range of radio frequencies, typically designated for a particular type of communication or broadcasting service. These bands are segments of the electromagnetic spectrum allocated for uses such as radio, television, mobile phones, or Wi-Fi.

Usage

The term "frequency band" is used to categorize and manage the radio spectrum. It refers to the slice of frequencies between an upper and lower limit. * Regulatory bodies assign different frequency bands for different services to prevent interference. * A new frequency band was auctioned for 5G mobile networks. * The satellite operates in the Ku frequency band.

Advanced Usage

• "to operate in a frequency band": Describes a device or service using a specific range of frequencies.
  • The wireless microphone operates in the UHF frequency band.
• "allocation of a frequency band": Refers to the official assignment of a frequency range by a governing authority.
  • The allocation of this frequency band for amateur radio is international.

Variants and Related Words

• Band (n): Often used as a shortened, informal form of "frequency band."
  • The device switches between multiple bands to find the strongest signal.
• Bandwidth (n): The width or capacity of a frequency band, measured as the difference between the upper and lower frequencies.
  • A wider bandwidth allows for faster data transmission.
• Waveband (n): A largely synonymous term, especially common in British English.

Synonyms

• Channel: Often implies a narrower, specific frequency within a band used for a single communication path.
• Spectrum allocation: A more formal term referring to the assigned frequency range.

Related Phrases

• Frequency spectrum: The entire range of all possible frequencies of electromagnetic radiation, of which a "frequency band" is a small part.
• Out-of-band: Refers to signals or communication occurring outside the designated or expected frequency band.
  • The filter removes out-of-band interference.
