Channel spacing, also known as
bandwidth, is a term used in radio
frequency planning. It describes the frequency difference between adjacent allocations in a
frequency plan. Channels for
mediumwave radio stations, for example are allocated in internationally agreed steps of 9 or 10
kHz: 10 kHz in ITU Region 2 (the Americas), and 9 kHz elsewhere in the world.
