Geostationary satellites are located in orbit approximately 36,000 kilometres above the equator. A roundtrip time to a satellite for data needs about 250 msec, the 2-way protocol latency is about 600 msec including SurfBeam system latency. To mitigate latency, which would impact on TCP throughput and web browsing speeds, a Performance Enhancing Proxy (PEP) and Web acceleration are integrated into the SurfBeam modem and DOCSIS head-end system.
