Boosting SNG

The document discusses satellite communication modulation schemes and their use cases. It mentions 8PSK modulation being used for space segment with 5Mbps throughput and no additional rain margin. It then discusses switching to 16APSK modulation for higher throughput up to 300+Mbps but with lower efficiency and sharing potential. Based on data rates and efficiency, it evaluates when different modulation schemes are best used for very high, medium, and high rate link applications.
