TDMA

Perhaps the best known V-SAT network architecture is the Multi-Frequency Time Division Multiple Access network, which is used around the world for low speed (16 Kbps to 4 Mb) data communications, such as credit card processing and verification, point-of-sale inventory control and general business data connectivity.

DAMA

A Demand Assigned Multiple Access, system is typically a single hop satellite transmission network, which functionally allows direct connection between any two nodes in a network among many users sharing a limited pool of satellite transponder space.

SCPC

Single Channel Per Carrier, is a point-to-point and multipoint technology, making it the V-SAT equivalent to conventional leased lines. SCPC is used for economical distribution of two way duplex or simplex data broadcasting for audio, video and data communications. In an SCPC system configuration, user data is transmitted to the satellite continuously.

DVB-S

Similar to SCPC technology, DVB-S can deliver high speed data connectivity to the home for almost anything that can be digitized, whether for High Definition TV, multiple channel Standard definition TV (PAL / NTSC or SECAM) or even exciting new broadband multimedia data and interactive services.

DVB-S2

The latest innovation in satellite transmission technology, is 30% more powerful and efficient than DVB-S, supports a much wider range of applications and is quick and easy to install. It is used for access to internet services as well as for point-to-point and multipoint applications. Data is transmitted via a DVB-S2 modulator and is received on a DVB-S2 Demodulator/Receiver and vice verse. DVB-S2 also can be configured as a simplex or a duplex dedicated link.
