Why is C-band so important for satellite services in Asia-Pacific region?
C-band is heavily used for satellite communications in Asia-Pacific Region for a multitude of services including: very small aperture terminal (VSAT) networks, internet services, point-top-multipoint links, satellite news gathering, TV broadcasting to satellite master antenna television (SMATV), direct-to-home (DTH) receivers and feeder links for mobile satellite service. The wide coverage of satellites in C-band enables services in developing countries, in sparsely populated and geographically remote areas, and over large distances (e.g. providing program content and data distribution between continents)
Due to its ubiquitous coverage, high availability and instant connectivity, C-band FSS plays a key role on the socio-economic development of many countries to provide vital services and is also crucial for disaster relief operations. This band is also used by governments in conjunction with international commitments; for example, the World Meteorological organization (WMO) uses this band to distribute meteorological data throughout the world and maritime and aeronautical safety related information is relayed through stations operating in this frequency band. Furthermore, due to its lower frequency, in particular in regions characterized by high rain attenuation, C-band is the only realistic satellite band where FSS services can be provided with high availability.
