Maximum usable frequency
Maximum usable frequency (MUF): In radio transmission using reflection from the regular ionized layers of the ionosphere, the upper frequency limit that can be used for transmission between two points at a specified time.
Note: MUF is a median frequency applicable to 50% of the days of a month, as opposed to 90% cited for the lowest usable high frequency[?] (LUF) and the optimum traffic frequency (FOT).
