VSAT stands for Very Small Aperture Terminal. It is abbreviation for the satellite terminal which has small diameter antenna system ( 90cm-240cm)

Package Delay is the travel time of the signal from transmitter station to the receiver station over satellite. For the single hop satellite connection this delay is around 240ms. This delay is caused by the distance between the satellite and the location on the Earth.

Because of the satellite communication structure it takes approximately 240-250ms for a package to reach from one point to another one. This delay is much lower on terrestrial lines. Except this delay factor there is no difference between satellite connection and terrestrial connection about running of the applications. The applications like VoIP, Video Conference, SAP can run without any problem over satellite.

Shared satellite internet is an appropriate internet solution for small and medium companies that have low internet traffic and few computers. It provides surfing on the web, receiving/sending e-mails over the satellite. Moreover because of the system is sharable, it is economical.

Dedicated satellite internet is the solution for medium and big size companies that high internet traffic. Dedicated type solution which uses dedicated satellite capacity, supports high performance required VOIP, video conference applications.

TDMA and SCPC are two different methods that used in VSAT systems. Each terminal uses the same carrier in TDMA system. Using of BOD ( Bandwidth on Demand ) in TDMA carrier allows usage of satellite capacity more efficiently. Each single point(office) can communicate with other points directly in the mesh structured TDMA system.

In SCPC based system, terminals can communicate directly with only one point.(with Center) .
In addition, carriers are always on so even there is not traffic on the system the capacity of the satellite is used in SCPC system.

In conclusion we recommend TDMA if you will have data, voice connection between your offices otherwise SCPC.

For our satellite connection solution basically you need antenna and as indoor unit satellite modem for each location. The customers do not have to buy the hardware; customers can rent the hardware from Balkan Telekom for special projects.
