VSAT

Short for Very Small Aperture Terminal, an earthbound station used in satellite communications of data, voice and video signals, excluding broadcast television. A VSAT consists of two parts, a transceiver that is placed outdoors in direct line of sight to the satellite and a device that is placed indoors to interface the transceiver with the end user's communications device, such as a PC. The transceiver receives or sends a signal to a satellite transponder in the sky. The satellite sends and receives signals from a ground station computer that acts as a hub for the system. Each end user is interconnected with the hub station via the satellite, forming a star topology. The hub controls the entire operation of the network. For one end user to communicate with another, each transmission has to first go to the hub station that then retransmits it via the satellite to the other end user's VSAT.

VSAT solutions was designed and implemented to provide the most cost effective and most powerful Internet access services from any location in Africa. This is the primary application of the system and services for the majority of users depend on their requirements.

Satellite modem and antenna dish is completely separate from the user PC-workstations and is not integrated with local customer equipment. As a stand-alone solution it eliminates possible support and operational problems relating to customer PC-workstation or network equipment. Field service and support is merely the exchange of faulty units and does not require extensive on-site engineering services.

VSAT solution is based on satellite communication channels and Teleport services. Operating on a Satellite and with first tier Internet access to provide the most effective and integrated Internet Access solutions.
