2.2.1 Frequency plans
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).
2.2.1.1 Frequency Channel Plan A, B and C
Transmit-to-receive channel spacing for frequency channel plans A, B and C is 69
MHz. 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).
