VSAT
VSAT is a small telecommunication earth station that receives and transmits real-time data through a satellite.
VSAT is a technology commonly known as a private earth station. Earth station is designed to transmit and retrieve data signals through satellite signals. VSAT includes the term "very small" which refers to the size of the antenna on the VSAT dish.
The antenna is typically about four feet in diameter and consists of a low-noise converter that receives the satellite signal, and a Block Upconverter (BUC) that transmits the signal for radio waves. The antenna can be mounted on the ground or it can be mounted on the roof.
VSAT end users require a box that interfaces between the user's computer and an external antenna with the transceiver. The transceiver sends or receives signals to a satellite transponder in the sky.
Satellite Earth Station sends and receives signals from computers that act as a hub for the system. Each end user is connected to the hub station via a satellite in a star topology.
For one end user to communicate with the other, each transmission must first go to the hub station which transmits it via satellite to the other end user's VSAT. VSAT handles data, voice, and video signals.
Most VSAT antennas range from 30 inches to 48 inches. Data rates typically range from 56 Kbps to 4 Mbps.
VSATs are most commonly used to transmit:
VSAT is commonly used to transmit the following:
Narrowband data:
This includes transactions such as credit cards, voting or radio-frequency identification (RFID) data, or supervisory control and data acquisition (SCADA) data.
Broadband data:
Broadband data for the provision of satellite Internet access Voice over Internet Protocol (VoIP) or video at remote locations.
VSAT systems provide high-speed, broadband satellite communication for Internet or private network communication.
