SATELLITE INSTALLATIONS

Broadband in Africa

"Broadband is not a consequence of economic growth, it is a cause"

 

Avanti recently sponsored a report written by the Commonwealth Telecommunications Organisation (CTO), some of the findings included:

 

• 341 million people in sub-Saharan Africa still live beyond the reach of a terrestrial fibre optic network

• In June 2012, eight countries remained 100% dependent on satellite for their international connectivity

 

A very small aperture terminal (VSAT) is a two-way satellite ground station or a stabilized maritime VSAT antenna with a dish antenna that is smaller than 3 meters.

 

The majority of VSAT antennas range from 75 cm to 1.2 m. Data rates range from 4 kbit/s up to 4 Mbit/s some upgraded modules can even reach a max downlink of up to 16 Mbit/s. VSATs access satellites in geosynchronous orbit to relay data from small remote earth stations (terminals) to other terminals (in mesh topology) or master earth station "hubs" (in star topology).

 

VSATs are used to transmit narrowband data (e.g. point-of-sale transactions using credit cards, polling or RFID data, or SCADA), or broadband data (for the provision of satellite Internet access to remote locations, VoIP or video). VSATs are also used for transportable, on-the-move (utilising phased array antennas) or mobile maritime communications.

 

Internet via satellite enables you to break free from internet problems and have a permanent two way connection to the Internet. Enjoy always-on, fast, satellite internet access whenever you need it – no issues with cable theft and phone lines. Save many hours delay downloading large files, surf the web, download e-mail. No more waiting for your connection.

 

Typical Applications

• Companies requiring highly reliable service.

• Small to Medium Enterprise.

• Rural locations, lodges, farms, mines, schools etc. (where no broadband service is available).
