2.2.1 Frequency plans
The SC5800 Outdoor Units operate in the 5.725 GHz to 5.850 GHz ISM frequency
band. The SC5800 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 optimize 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).
