What is VSAT Internet?
What is VSAT Internet?
A very small aperture terminal (VSAT) is a small-sized earth station used in the transmit/receive of data, voice and video signals over a satellite communication network, excluding broadcast television.
What is the difference between VSAT and Inmarsat?
Coverage: Inmarsat provides almost global coverage for BGAN, with terminals in South America, Africa, Europe or Asia. Meanwhile, VSAT, in most cases, needs separate contracts on different satellites and teleports to achieve global coverage.
How does a VSAT work?
A VSAT user requires a box to read between the user’s computer and an outdoor antenna which has a transceiver. The transceiver is used to send and receive signal to and from a satellite transponder via an earth based station known as ‘hub’ which is interconnected with the satellite.
How much does a VSAT cost?
A standard 1m diameter VSAT system requires a very large antenna and can cost in the region of US$50,000 toUS$60,000. The radome for the Sea Tel WaveCall 4006, for example, is 1.2m in diameter and 1.5m high, and weighs more than 100kg.
How fast is VSAT Internet?
Internet Speed of Fiber vs. DSL vs. Cable vs. Satellite
|Download Speed||0.2 Mbps – 2,000 Mbps||12 Mbps – 100 Mbps|
|Upload Speed||0.128 Mbps – 1,000 Mbps||3 Mbps|
|Latency||12 ms – 33 ms||610 ms|
|Packet Loss||0% – 1%||>1%|
What are the disadvantages of VSAT?
Following are the disadvantages of VSAT: ➨As mentioned it requires clear Line of Sight between VSAT dish and satellite in the space. ➨The malfunctioning of satellite and Hub station (in case of star topology) will lead to disruption of VSAT services.
What band is BGAN?
BGAN uses L-band frequency, with the terminal receiving (Rx) frequencies of 1525.0-1559.0MHz and transmitting (Tx) frequencies of 1626.5-1660.5MHz.
What is VSAT equipment?
Apr 6, 2019. Very Small Aperture Terminal (VSAT) is a ground station with dish antennas that transmits and receives data from satellites. The dish antenna we see in houses for D2H or at the top of tall buildings is a simple example of a VSAT terminal.
How much does VSAT cost in India?
about 3.5 Lakhs
Cost of a VSAT is about 3.5 Lakhs. VSATs are readily available. Each VSAT provides 2 ports for connecting data terminals.

What is VSAT technology?
Very Small Aperture Terminal or VSAT technology is basically a two way satellite groud station that facilitates satellite communications of voice signals, data signals and video signals and connections.
What is VSAT (very small aperture terminal)?
A very small aperture terminal (VSAT) is a data transmission technology used for many types of data management and in high-frequency trading. VSAT can be used in place of a large physical network as it bounces the signal from satellites instead of being transported through physical means like an ethernet connection.
How does the VSAT measure signal quality?
The VSAT periodically measures the signal quality (e.g. C/N) of the outbound carrier and reports it to the NCMC. The NCMC determines the transmit power requirement of the VSAT based on the quality report from the VSAT and its own measurement on the signal quality of the inbound carrier and command it to the VSAT accordingly.
What are the service subscription profiles of the VSAT?
Rep. ITU-R S.2278 11 – service subscription profiles of the VSAT (e.g. maximum transmission speed of outbound/inbound direction); – the current number of terminals already authorized or currently in operation (to prevent overloading of satellite resources). 4.2 Control and monitoring functions during the operation of a VSAT
