INTRODUCTION

• Generations of satellites in the Internet
• key questions arising in the design of a
  satellite-based system
• 1) Satellite v/s terrestrial networks
• 2) Elements of satellite-based Internet link
  
• 3) Design issues

4
HISTORY

• 1973 Two European computers linked to an
  American network.
• 1996 The first consumer satellite Internet
  service went into service
• 1998 Intel has invested in satellite Internet
  businesses
• 2000 America Online Inc, and Hughes tested a
  high-speed satellite Internet service in 16
  cities.

5
HISTORY (contd..)

• 2002 StarBand Communications Inc. and Hughes
  offer satellite Internet
• 2005 WildBlue's brought its satellite Internet
  service to rural areas around US
• 2008 Google and HSBC plan to provide cheap,
  high-speed net to Africa and other emerging
  markets.
• 2009 Hughes satellite internet service is
  available at US military bases.

CURRENT TRENDS

• Advanced Satellite Internet Modems.
• Secure communications - 3DES Encryption.
• Enforced Quality of Service (QoS).

SCOPE

• Areas with no cable connection.
• Fairly decent upload and download speed.
• Latency is reducing day by day, suiting
• real-time applications.

STATISTICAL DETAILS
25
CONCLUSION

• Satellite Internet promise a new era of global
  connectivity, but also present new challenges to
  common Internet applications.
• Further improvements can be made at the protocol
  level by extending the current TCP standard.

26
FUTURE OF TECHNOLOGY

• Improving the availability.
• A transport and proxy for real-time streaming
  traffic within IDS.
• Improved Security and QoS for all traffic flowing
  through IDS.
• Information mined from warehouse and kiosk
  databases

27
Contd..

• Future launches
• W3B
• KA-SAT
