SATELLITE: Why?? (1)

BANDWIDTH

Satellite networks offer

Broadband Links

Bandwidth independency from the number of users for Broadcast and Multicast transmissions



COVERAGE

Satellite coverages enable the international and intercontinental extension of the networks overcoming

geological constraints

poor terrestrial infrastructures



RELIABILITY

EXPANDABILITY

FLEXIBILITY


SATELLITE SERVICES EVOLUTION (1)

FROM

CENTRALISED INSTALLATIONS , LARGE DIMENSIONS (Dant from 13 m to 3.7 m),

HIGH POWER (Pout from 1500 W to 150 W) HIGH INVESTMENT AND OPERATION COSTS

TO

DISTRIBUTED TERMINALS, SMALL DIMENSIONS (Dant from 3.7 m to 60 cm),

REDUCED POWER (Pout from 150 W to 1 W) REDUCED INVESTMENT AND OPERATION COSTS


SATELLITE SERVICES EVOLUTION (2)

SATELLITE PARTECIPATES IN THE GENERAL EVOLUTION OF TECHNOLOGY:

- WIDESPREAD DIFFUSION OF THE INSTRUMENTS OF INFORMATION TECHNOLOGY

- WIDESPREAD ACCESS TO AN INCREASING NUMBER OF INFORMATION

- DIFFUSION OF THE CAPABILITY OF CREATING AND TRANSMITTING CONTENTS

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


THE FUTURE (2)

Enhanced satellite/terrestrial networks integration:

integration of DAMA networks with WLL, xDSL

integration of Multimedia Platforms with optical fibers.


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


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
