How to Site VSAT Antenna

In the United States, VSAT systems have developed rapidly. There they have supported the introduction of new communications services that have become essential to the efficient operation of many corporations and business. One of the results of this large market is that production costs of small terminals have fallen to relatively low levels. However, it could be argued that VSATs still represent a niche market and have yet to achieve their full potential. In those countries where the regulatory environment is liberal, there is very substantial competition from other technologies, e.g. optical fiber, conventional cable, microwave links and wireless personal communication networks (PCNs).

VSAT also plays a vital role in those Third World countries with virtually no terrestrial telecommunications infrastructure: as an example, VSAT data services based on spread spectrum are now available from the telecommunications administration in India.

Researches have proven that in those developing countries where satellite communications have been introduced, there has followed substantial economic growth, a clear indication that low cost low complexity VSAT systems can be of potential benefit to the Third World where a communications infrastructure may be lacking.

To satisfy domestic and international requirements, two-way VSAT networks are now widely used, which offers voice and data services or even two-way video conferencing. These developments are causing communications service to evolve around customer requirements, either within a country or, increasingly, on an international basis. Examples are news distribution services, voice and data links to isolated locations (mineral exploration sites and oil platforms) and non-standard service options not available from terrestrial communications networks.

 The liberal regulatory environment prevailing in the United States has enabled organizations to provide a wide range of communications services (for themselves and others on a commercial basis) by allowing acquisition of earth terminal equipment and acquisition or leasing of satellite transponder capacity from various satellites (to provide coverage of service areas with adequate power levels) and the ability to procure VSATs with the appropriate features (voice and data at different rates). Moreover, the resources offer end-to-end service (including equipment installation, interfacing between VSATs and customer terminal equipment and maintenance support).
