The MDR5800 Outdoor Units operate in the 5.725 GHz to 5.850 GHz ISM frequency
band. The MDR5800 has predefined frequency channel plans (termed A, B, C and D).
The MDR2400 Outdoor Units operate in the 2.400 GHz to 2.4835 GHz ISM frequency
band. The MDR2400 has predefined frequency channel plans (termed A, B and D).
2.2.1.1 MDR5800 Frequency Channel Plan A, B and C
The channel spacing is based on the bandwidth occupied by the spread spectrum
signal (approximately 17 MHz) and is used to optimise link performance. In the case
of plan A, plan B and C, note that both Outdoor Units of a link must be set up to the
same frequency channel plan (i.e. A, B or C).
