• It is a "single-hop," terminal-to-terminal
  connectivity, which keeps all the branch offices
  in contact with remote locations.

Star Topology

• The Star VSAT network is set-up either as a
  Shared or Private Hub.
• Star topology network will create two-way
  communications between any number of sites and a
  central hub.

Advantages

• Use a satellite communication for a company
  solution can benefit from reduced operation
  costs.
• Low coast of installation
• No cable running (Wireless)
• Pure digital picture for video transmission
• And more..

10
