Program SCOPE
The Ka-Band frequency spectrum allocated to satellites and relatively unused for many years has now become the hottest commodity in satellite communications. Although a portion of it has been lost to terrestrial interests (LMDS) in the U.S., the portion of the spectrum remaining to satellites has been allocated to service by LEO, GEO and shared use with feeder links. Many recent filings in the U.S. and worldwide have been asking for Ka-Band slot assignments to operate national. regional and global systems.
This unprecedented reversal of fortune for a portion of the spectrum judged almost unusable because of the fear of severe and unpredictable rain impediments and lack of suitable technology. has now spurred the commitment of billions of dollars of private investments and promises to open a new era in satellite communications which will bring the visions of a Global Information Infrastructure within the reach of everyone everywhere at an affordable price.
At the same time, recognizing the importance of the role that satellites would play in this field, the Communications Research Laboratory of the Japanese Ministry of Posts and Telecommunications, in cooperation with the State of Hawaii and the Japan-US Science. Technology & Space Applications Program. sponsored the first International Workshop on Satellite Communications for the Global Information Infrastructure. This was held on the island of Maui, Hawaii in November 1995.
Many of the papers presented there and the ensuing discussions pointed out that the majority of the satellites which were proposed to play a future role in the GII would use the Ka-Band. Lower frequencv bands were, in most cases, either too congested or did not provide sufficient bandwidth for the envisaged needs.
It was natural then, for members of the respective organizing Committees that attended both events, to consider combining the two into a single event, with expanded scope. The combined themes should provide a great degree of synergy, enhancing the value of attending the Conference to all participants. as shown in this announcement.
