Usage of VSAT satellite technology in business

Speed and volatility of communications is among the biggest challenges faced by thousands of companies operating in hard-to-reach and remote places. Hence, it has become common for companies to leverage satellite systems that allow them to have an agile and independent communications network. This is where VSAT satellite technology. VSAT Satellite Connectivity in Africa is especially quite popular.   Such a technology makes use of a type of antenna that receives and transmits data.  Such antenna comprises of small terminals can be installed in distributed sites, and connected to a central Hub owing to a satellite. 

VSAT: How does it operate and what does this network support?

VSAT satellite technology tends to operate in varying sizes, shapes and frequencies.   C-band and Ku-band are the most popular operating frequencies, and is known to work well with Point-to-Point (Customized Private Hub) and Star Network (Private Hub), and would be capable enough to support a large number of places and Mesh Systems. It is ideally smaller than star systems (between 5 and 30 sites in general).

Owing to this operating environment, such antenna can provide satellite services that can effectively support LAN, internet, video and data communications, as well as IP voice. This helps in the creation of private and public networks for a dependable communication. Details of VSAT Teleport in Africa and more can be found online.

VSAT technology tends to represent an affordable solution for companies that need to have an independent communication system, while connecting several dispersed sites.

Selecting the ideal band

At the present, there are three categories of band used in the VSAT system. One can avail 20/30GHz at Ka-band, 12/14GHz at Ku-band and 4/6 GHz at C-band. C-band has the advantage of being a mature technology and boasts of stable space transmission as well. However, it can interfere with ground microwave of the same band and its location is limited when used in cities. Ka-Band in Africa is pretty popular and does not have interference with ground microwave of the same band. It has smaller aperture as well. However, it can be a bit of unstable space transmission. As a result, there is a need to keep adequate link margin for Ku-band when designing the system. Ka-band is not applied extensively at the present owing to complicated technology and limited channel resource. VSAT C band is typically used for voice transmission, while -band is generally available for data transmission.
