Satellite and wireless: a long history • Satellite communications are, ideally, the synthesis of

two powerful dreamers:– Arthur C. Clarke and – Guglielmo Marconi. – The former is the father of the satellite in the geostationary orbit,

the latter is the father of wireless communications.

• In April 1912, one hundreds years ago, the 705 surveyors from the Titanic disaster reached the Harbour of New York

• Britain's postmaster-general summed up, referring to the Titanic disaster, "Those who have been saved, have been saved through one man, Mr. Marconi...and his marvelous invention."

Wireless communications and society

• the conference will be held in Italy, reinforcing the scientific and industrial links across the Atlantic Ocean, contributing to make “mankind free from many of the burdens imposed by present economic conditions”.

• These words were pronounced by G. Marconi a few months lather the disaster in October 1912.

Space belongs to mankind: a dream?

• Since the very beginning the use of space (inception of the Outer Space Treaty of 1967) has been an international and global problem:

• the, international law regarding the use of outer space by nations and individuals has been dominated by the res communis doctrine, the concept that space belongs to mankind

• the socio-political and economic environment makes the treaty more of a hindrance than a safeguard.

Space telecommunications: orbit and frequency allocation management

• In the last 50 years communications satellite technology has been driven by the need of increasing the communication information rate to allow the geostationary access to all the nations and to the widest user’ number, increasing the dimension and power of satellite and decreasing at the same time the dimensions of the user terminals.

• The necessary regulation environment realised inside the ITU (International telecommunication Union) has been the fundamentalmediation table between different national interests.

• The progressive exploitation of the orbit/frequency resources and the resulting likelihood of congestion of the geostationary-satellite orbit resulted in the establishment (and introduction into the ITU regulatory regime) of frequency/orbital position plans in which a certain amount of frequency spectrum is set aside for future use by all countries, particularly those which are not in a position, at present, to make use of these resources.

The Estel IEEE-AESS Conference on Satellite Communications

• The Conference is presenting 5 macro-areas connected by the “fil rouge” of advancing one step in improving life of people:– exploiting communications performance, – introducing new services according to the full internet

paradigm, – simplifying the bandwidth/orbit access and – decreasing the final cost for the users.

• In this wide area it is possible to outline two of these elements, which can open a new era in Satellite communications: – MIMO communications and – Software Defined Radio. – These two technologies can be the key elements for a real

revolution in thinking and designing new satellite payloads and the correspondent blocks on ground.

• They give the possibility of redefining the satellite payload subsystems not only for reduction of weight, power consumption and costs,

• but also a complete unknown freedom in re inventing the communication system functionality, similar to the digitalisation revolution which has completely changed the communication networking.

11

• In the spirit of outlining the social importance of Communications since the first SOS’s launched by the transatlantic Britannia and Titanic,

• It has to be noted the emphasis that the role of satellite has in emergency communications services.

Future Satellite Communication SystemsMacro area # 4: Future Satellite Communication Syste ms

• Next Generation Mobile, Broadband and Broadcast Satellite Systems• Channel Modeling for EHF Satellite Communications• Millimeter Wave Technology and Devices• Multi-Gigabit Communications• New Constellation Design



15

• This macro area aims to increase the bandwidth availability: – using higher frequency bands, – new constellations or – new transmission modes possible with the realisation of twisting

radio waves around the propagation direction.

• This macro area offers a vision of the future systems, where there is a lot of room for researches and engineers, who are animated by the same spirit of G. Marconi, which can be synthesised “contrary to common opinion”.

• knowing the outer space is the engine to any space activity.

• This year Italy we hosts at the same time the IAC conference in Naples.

• Therefore there is the possibility to create a marvellous mega event on Space, with:– time sharing of ideas, – impressions and – participation to realise a unique synergy between all

the aspects of the satellite and space technologies.
