Wireless Broadband through VSAT

The need to stay connected at all times is fuelling the demand for VSAT  (Very Small Aperture Terminal) services. As the Internet drives more traffic due to innovations in mobile services, more and more customers are signing up for wireless broadband service with larger coverage, either for personal or business use.VSAT is a form of satellite communication system that serves both residential and business customers who need reliable access to wireless broadband in remote locations.
VSAT works by processing signals from a box that communicates with a computer and an outdoor antenna equipped with a transceiver. The transceiver transmits or receives signals to and from a satellite transponder. The satellite processes signals from terrestrial station computer that acts as a hub. Both end-users are connected to a hub station. The signal would go first to the hub station which would send the data to the satellite, which in turn would beam the signal to another transceiver on the ground. VSAT can process voice, data and video signals.Geo-Synchronous satellites cover 30% of the earth’s surface, providing connectivity anywhere in the coverage area.
A satellite can focus on a specific region, and multiple satellites can form a network to extend the coverage globally. VSAT offers reliable connectivity in remote locations such as rural areas, coastal regions, mountainous regions, oceans and exploration sites. VSAT can also immediately provide a backup connectivity system when the terrestrial networks malfunction. Companies that cannot afford even a second of interruption in their wireless broadband service will find VSAT indispensable. VSAT is ideal for stock exchanges, banks, and 24×7 companies that require continuous delivery and access to real-time data.
Because of the extensive wireless broadband coverage of VSAT, the initial cost of the VSAT system is lower than that of networks built specifically for terrestrial infrastructures. Space-segment savings are possible through advancing modulation schemes and coding techniques, which facilitate the transmission of  digital information from the satellite. And since satellites are more powerful, they require cheaper and smaller terrestrial antennas.
The cost of Australia satellite wireless broadband is expected to decrease due to technological advances. New VSAT technologies are using the Ka band which has a higher bandwidth rate. Current FSS satellite systems have enormous capacity yet relatively low cost. VSAT provides reliable wireless broadband for Internet telephony, digital audio broadcasting and high-speed data communication in areas not reached by conventional broadband service providers.
VSAT is attracting more corporate users as the cost of its wireless broadband connectivity decreases. Costs have been more attractive since introduction of Direct to Home (DTH) television broadcasting. As a result, VSAT wireless broadband providers began to extend their market to include the consumer market. The market for VSAT has grown due to the adoption of open standard which made TVRO terminals cheaper. GSO satellites which use Ku band frequencies require smaller remote terminals, making VSAT more affordable.  Also, the advent of multibeam satellites improved connectivity arrangements, making satellite broadband more reliable.
