There are basically five types of networks employed
in VSAT operations.
Multipoint Network
These are data oriented networks that require voice. This provides
for two-way data, voice and multi-media operations with a star
type network configuration that connects one or more main sites
to various remote sites.
Full-Meshed Network
Full-Meshed Designed Network is used for voice oriented networks.
There is no central hub and each site can communicate directly
with all network nodes. It employs single satellite hops between
each network nodes, which enables superior voice quality, and
efficient fast-response data connections.
Hybrid Voice and Data Network
It is a hybrid of Multipoint and Full-Meshed network. This system
takes separate voice and data interfaces at the remote site
and then processes this and combines them onto a single cable
connecting to the antenna. The system is capable of a wide-range
of advance telephony and PBX voice services and provides an
efficient LAN/WAN network service.
Single Channel Per Carrier (SCPC) -
Point-to-Point
SCPC circuits are point-to-point circuits that provide two-way
communication between VSAT terminals located at two sites. It
is a very flexible system and has the capability to handle multiple
data types over multiple protocols.
Broadcast Networks
Broadcast Networks provide for the transmission of data, video
and audio files to any number of users. This one-way system
provides an uplink from the central site and each remote site
downlinks (receives) only.
