Satellite Communication

• Satellite is a microwave device consisting of
  receiver, repeater and regenerator in orbit
• Satellite transmission involves sending signals
  to satellite that receive, amplify, and transmit
  back to earth

Capabilities of Satellite Transmission

• Point-to-point transmission
• To transfer large volume of data
• Voice, data, etc communication
• Video conference
• Point-to-multipoint transmission
• Data communication
• Internet
• Video conference
• Broadcast services such as television

5
Satellite Communication is Best Suited

• For signals originating from a single site with
  simultaneous distribution to many remote sites
• For remote sites which are located in
  geographically dispersed areas
• For delivery of large volumes of data to remote
  sites with relatively small volume return channel

6
Multimedia Applications

• Applications such as text, image, video and
  real time signals served on a common transmission
  media are known as Multimedia Applications.

7
Multimedia Applications (Contd)

• Significant Amount of Bandwidth is required.
• Broadband Infrastructure is required.

8
ETCs Readiness

• ETC is now building such infrastructure in the
  capital city and major towns using optical fiber
  and ATM switches.
• In order to provide these services for users at
  remote and rural sites a Broadband VSAT network
  is also under implementation.

What Is Broadband VSAT Network?

• It is a VSAT network designed to receive and
  transmit wideband signals
• TX up to 512 kbps from a remote station
• RX up to 45 Mbps and any number of TV channels
• A VSAT network that supports multimedia
  application.

10
What Is Broadband VSAT Network? (Contd)

• A Broadband VSAT Network is a flexible DVB-IP
  platform allowing multimedia services such as
  digital video, WAN, Internet, video-conferencing
  and rural telephony on a single infrastructure.

11
Benefits of Broadband VSAT Network

• Same resource can be shared by a group of users.
• Efficient Utilization of Resources.
• Multiple remote sites can get access to
  information concentrated in capital cities.
• High network availability
• Fast deployment
