In telecommunications, a guard band is a narrow, intentionally unused
frequency band that is placed between adjacent frequency bands to minimize
interference between them. It is used in
frequency-division multiplexing. Guard bands exist in both
wired and
wireless
Wireless communication (or just wireless, when the context allows) is the transfer of information (''telecommunication'') between two or more points without the use of an electrical conductor, optical fiber or other continuous guided transm ...
communications.
A guard band can also be licensed for use by low-powered devices such as a
private mobile phone network.
