Guard band
Guard bands are small, unused chunks of radio spectrum placed between two nearby frequency bands to prevent interference. They are used in systems that split signals across different frequencies (frequency‑division multiplexing) and appear in both wired and wireless networks. In some cases, guard bands are licensed for low‑power use, such as private mobile networks.
