A Hub is an earth station that acts as the central role of a star or "hub and spoke" network. The Hub station is composed of a large antenna and high-powered amplifiers. One advantage of this is to minimize the remote VSAT terminal antenna and amplifier size requirements. In a Hub station scenario, all surrounding VSAT traffic must pass through the station resulting in the inability for VSAT terminals to communicate directly with each other, even if their electronics allow for this.
