What term describes a specific frequency subdivision within a wireless band?

• A. Channel
• B. Band
• C. Subband
• D. Slot

Answer: (A)

A channel is the specific frequency slice allocated within a wireless band for a single communication. A wireless band covers a broad range of frequencies, and that range is divided into channels, each with its own center frequency and bandwidth. This separation lets multiple transmissions occur in the same band without interfering with each other. For example, in the 2.4 GHz Wi‑Fi band, several channels exist, each occupying about 22 MHz of spectrum, so devices can pick a channel and communicate there. The broader band is the entire spectrum; a subband would be a smaller portion within a band but isn’t the standard term for a single communication path in this context, and a slot refers to a time division rather than a frequency division.
