INTRODUCTION
Generations of satellites in the Internet
key questions arising in the design of a satellitebased
system:
1) Satellite v/s terrestrial networks
2) Elements of satellite-based Internet link
3) Design issues
CURRENT TRENDS
Advanced Satellite Internet Modems.
Secure communications - 3DES Encryption.
Enforced Quality of Service (QoS).
APPLICATION AREAS
Rural and remote areas.
Internet based applications.
Disaster places.
War fields.
SCOPE
Areas with no cable connection.
Fairly decent upload and download speed.
Latency is reducing day by day, suiting
real-time applications.
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.
