VSAT stands for "Very Small Aperture Terminal" and refers to receive/transmit terminals installed at dispersed sites connecting to a central hub via satellite using small diameter antenna dishes (0.6 to 3.8 meter).
VSAT technology represents a cost effective solution for users seeking an independent communications network connecting a large number of geographically dispersed sites. VSAT networks offer value-added satellite-based services capable of supporting the Internet, data, LAN, voice/fax communications, and can provide powerful, dependable private and public network communications solutions.
Generally, these systems operate in the Ku-band and C-band frequencies.
- Ku-band based networks, are used primarily in Europe and North America and utilize the smaller sizes of VSAT antennas.
- C-band, used extensively in Asia, Africa and Latin America, require larger antenna
