MFN - Multi Frequency Network

A Multi Frequency Network is a network of transmitting stations that all use their own frequency. The main reason to use different frequencies for the stations is to prevent co-channel interference between the transmitters. Frequencies can only be re-used after a certain seperation distance between the stations using the same frequency.

The term is mainly used in association with the term Single Frequency Network (SFN) in the frequency planning of broadcasting stations.
