multi frequency network (MFN)

In contrast to common- frequency networks, multi-frequency networks (MFN) operate with different transmission frequencies. The technology of multi-frequency networks is known from terrestrial broadcasting, where all neighboring transmitters transmit on different carrier frequencies.

Each transmitter in a multi-frequency network irradiates its own transmission area, which represents its own radio cell. One of the main advantages of multi-frequency networks is that there is no interference between adjacent channels.

The frequencies used in multi-frequency networks can only be used again at a certain distance from another transmitter. The distance must be large enough to ensure that the different transmitting frequencies do not interfere with each other.
