Satellite communication uses satellites in geosynchronous orbit to provide communication coverage over wide areas of Earth. There are about 750 communication satellites currently in orbit. Satellites can transmit signals over long distances with only a 0.3 second delay and transmission costs do not depend on distance between locations. Common satellite communication protocols include FDMA, TDMA, and CDMA which divide available bandwidth between users. VSAT networks use small satellite dishes for localized communication networks like banking. DirecPC provides high speed internet access to users through a satellite dish and computer card.
