System Gain vs FEC Coding
This table shows the relationship between modulation, FEC coding, system gain, capacity and coverage.
Maximum FEC coding results in the highest system gain, the best coverage but the least capacity
Minimum FEC coding results in lower system gain, lower coverage but higher capacity
No FEC coding results in the lowest system gain, the lowest coverage but the highest capacity
This table defines the modulation order based on gross capacity and receiver sensitivity:
