RSV requires 1.5 dB incremental power to provide the same level of service. 1/100 bits lost 1/100,000,000 iDirect Other RSV Other RSV Shannon Limit At 5dB Eb/No iDirect Operating at 10x-9 is extremely important for higher TCP throughputs. TCP is very sensitive delay and loss. At 10x-7 TCP throughput over satellite drops to an poor 5% throughput (without acceleration). At 10x-9, TCP throughput is at about 98% throughput with acceleration. The additional power provided by TPC, allows for automatic uplink power control, thus higher availability. This additional power can also be used to run carriers in a bandwidth limited manner, thus saving recurring expenses. Standard Network Operating Range High Availability Slide
