What is VSAT installation?
VSAT, an acronym for Very Small Aperture Terminal, is the term used for a one-way or two-way satellite ground station consisting of a dish antenna smaller than three meters across. North American and European units usually operate in the Ku-Band frequencies and use smaller antennas.
What are components of VSAT?
A VSAT consists of two parts: a transceiver placed outdoors in direct line of sight to the satellite, and a device that is placed indoors to interface the transceiver with the end user’s communications device, such as a PC. The transceiver receives or sends a signal to a satellite transponder in the sky.
What is VSAT detail?
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 much does a VSAT cost?
Auto-pointing VSAT systems can range in price from $20,000 to $200,000 depending upon the type of system deployed. A trained technician is required for VSAT installations, so you will have additional costs with VSAT for initial fixed site installations.
What is VSAT Internet connection?
How does the VSAT work?
How does 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.
What type of antenna the earth station can use?
The most common type, though is a parabolic reflector antenna (a paraboloid of revolution, to be more specific). A horn antenna is used for full Earth coverage from a geostationary satellite.
How is communication carried out in a VSAT network?
Broadly VSAT network as a whole consists of VSAT terminals distributed across different regions on the Earth and Hub station located at one central place. Communication between Hub station and VSAT terminals is carried out using RF frequencies in different bands (e.g. C band, Ku band) as per applications and regions of use.
How to connect Cisco IP VSAT satellite WAN network modules?
This guide describes how to connect Cisco IP VSAT satellite WAN network modules to your network. It contains the following sections: The NM-1VSAT-GILAT network module provides Cisco modular access routers with two-way satellite WAN connectivity in Gilat SkyEdge-compatible satellite communications networks.
What kind of applications can VSAT be used for?
VSAT is used for many applications which include Internet access,distance education,telemedicine,telephony,banking,video conferencing and more. It makes use of already launced satellites to provide all these facilities. The interface to satellite is through disc antenna and various bands are in use.
Where are the hubs located in a VSAT network?
VSATs in all the CUGs use the same one Hub station. In distributed Hub network type, each network will have its own hub station known as “min-Hub”. This mini hub is located near the client’s premises. In this network, all the clients will have its own traffic hub dedicated to its own CUG.
