SATELLITE: Why?? (1)
BANDWIDTH
Satellite networks offer
Broadband Links
Bandwidth independency from the number of users for Broadcast and Multicast transmissions
3Ewds_jnc.pptEwds_jnc.ppt
SATELLITE: Why?? (2)
COVERAGE
Satellite coverages enable the international and intercontinental extension of the networks overcoming
geological constraints
poor terrestrial infrastructures

Satellite IP Broadcast (2)
Based on the encapsulation of IP packets into DVB Transport Stream. The DVB Stream is received via a DTH antenna and IP packets are de-encapsulated by an interface card.

THE FUTURE (1)
Enhance the integration of satellite networks with terrestrial ones
Increase the Frequency Bandwidth available on satellites
Decrease the cost of terminals to increase the use of bi-directional networks, to make return channel via satellite accessible also to
consumers and SOHO
19Ewds_jnc.pptEwds_jnc.ppt
THE FUTURE (2)
Enhanced satellite/terrestrial networks integration:
integration of DAMA networks with WLL, xDSL
integration of Multimedia Platforms with optical fibers.
20Ewds_jnc.pptEwds_jnc.ppt
THE FUTURE (3)
Introduction of Ka band
Increase of satellite G/T through the use of multiple spot beam coverages to reduce the size and power of the terminals
Improvement of On-Board Processing (OBP) techniques for on-board cross connection between spot beams
Standardization of systems to ensure interoperability and large volume production of terminals
21Ewds_jnc.pptEwds_jnc.ppt
DVB-RCS (1)
Development Program
Objective to design and develop bi-directional satellite terminals
meeting the DVB-RCS standard and therefore ensuring interoperability between terminals and HUBs from different manufacturers.
This way
to ensure large volume production for terminals
and therefore
to decrease the price of terminals
