Title: Broad Band VSAT Network


1
  • Broad Band VSAT Network
  • Presentation

2
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.

9
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

12
ETCs BB MM NW Structure
  • The Network consists of
  • MM network in Addis Ababa connecting users data
    center to ETCs Network
  • International Local Internet Teleports
  • Satellite Hub station and remote VSAT stations
