SYNCHRONIZATION TIMING IN A SPLIT LOCATION HUB

摘要

A split gateway hub for a bent-leg communication system is disclosed. The gateway hub includes: a modulator to modulate a bit stream into a signal to be transmitted to a remote terminal via a radio frequency (RF) signal; a Time Synchronization Application (TSA), geographically co-located with the modulator, to provide timing reference and synchronization to the remote terminal; a network access component to provide traffic for the bit stream; and an Inroute Group Manager (IGM) to manage the traffic to and from the remote terminal. In the split gateway hub, the IGM is disposed geographically remote from either the TSA or from the network access component, and the bent-leg communication system uses a satellite or a High Attitude Platform (HAP) for relaying the RF signal.
