The VSat satellite is the best solution for rural areas, where there is no telecom infrastructure
The term Very Small Aperture Terminal (VSAT) refers to a small fixed earth station. VSATs provide the vital communication link required to set up a satellite based communication network. VSATs can support any communication requirement be it voice, data, or video conferencing.
The VSAT comprises of two modules - an outdoor unit and an indoor unit. The outdoor unit consists of an Antenna and Radio Frequency Transceiver. (RFT). The antenna size is typically 1.8 metre or 2.4 metre in diameter, although smaller antennas are also in use. The indoor unit functions as a modem and also interfaces with the end user equipment like stand alone PCs, LANs, Telephones or an EPABX.
VSATs can typically be divided into two parts- an outdoor unit and an indoor unit. The outdoor unit is generally ground or even wall mounted and the indoor unit which is the size of a desktop computer is normally located near existing computer equipment in your office.
The VSat satellite is the best solution for rural areas, where there is no telecom infrastructure
VSAT satellite focus on a particular high density region and multiple satellites can work together to provide global coverage. This is very useful for remote locations (rural areas, ships and coastal regions, hills, etc) where there is limited or no terrestrial connectivity.Mobile Access: Mobile access has been another traditional strength of a satellite network. This makes TV broadcasters (for example) make broadcasts from anywhere – even when they are on the move. Another possible application could be mobile Internet access, while on the move.
Internet Access: A VSAT Network can provide Internet access in addition to the point to point WAN links. Its all set to create a next major wave in the consumer broadband industry with the launch of satellites operating in the Ka band offering very high throughput, especially in the non metro regions. ‘Always ON’ broadband Internet services are possible with VSAT networks.
VPN: Satellites support encryption of all data transmitted between two sites or multiple sites, which make the creation of Virtual Private Networks (VPN) possible. This is one reason why the VSAT networks could find more acceptance in the corporate and Government/ Defense connectivity requirements.
Scalable: VSAT networks can be easily and cost effectively be scaled to accommodate multiple locations across the globe. In fact, some of the largest customers of VSAT networks have as many as 10,000 sites on a single network!
Reliable: Satellite Networks are very reliable (having up-times in the magnitude of 99.5% and above) and have been field tested for many years now. Mission critical applications like Bank ATM’s, Navy and Point of Sale appliances use VSAT!
