November 2 - 4, 1998 Venice, Italy
Fourth Ka-Band Utilization Conference 1998 Program

Program Scope

As we prepare the program for the fourth edition of our conference, it is natural to reflect on some of the changes affecting our field of activity, since a number of significant events have taken place this past year that are bound to have a profound impact on the future of satellite communications:

• Iridium has completed its constellation and is preparing to provide global service.
  
• Teledesic and Celestri have joined forces and are defining a new system.
  
• Some companies have awarded contracts to begin work on their Ka Band systems.
  
• A number of applications have been filed :for high capacity systems at V Band.

The high level of activity is not reflected in our session on systems because the designers and market analysts have not finalized their work. On the contrary, we have a variety of papers on architecture and protocols, propagation, components and ground systems, indicating that the necessary ingredients to the realization of Ka Band systems are being developed and will be available to support the systems when they are defined.

In contrast to the past, this year we have scheduled some sessions to run concurrently in order to accommodate the papers received and to avoid overlap with the start of EMPS '98.
We hope that this will not cause any inconvenience to our attendees.
