Program SCOPE

The purpose of the Conference is to Promote the use of Ka band satellite systems. Initial acceptance of Ka band systems by international and regional operators has been limited by several factors, primarily:

1) significant propagation impairments in rainy weather,
2) the added complexity of the adaptive rain fade countermeasures needed to avoid unacceptably
high link margins for high availability services and
3) the higher costs and the risks associated with unproved technologies.

Throughout the 1980's, with the exception of Japan's domestic spacecraft, no operational application of commercial Ka-band satellite systems emerged. However, in the early 1990's pilot and pre-operational Ka-band systems - such as ETS, ITALSAT and ACTS - were built, launched and are providing important results in terms of propagation data acquisition, technology development and communications payload performance. Experience gained from these systems has increased confidence in the use of Ka-band satellite technologies, and today, the market appears to favor exploitation of Ka-band satellite communications technology.

The Conference, organized by Istituto Internazionale delle Comunicazioni (IIC), is planned for October 10, 11, 12, 1995 in Rome, Italy, for the purpose of disseminating information on the performance of existing Ka-band systems, presenting planned global fixed and mobile systems that will employ Ka-band and addressing regulatory issues, like world wide coordination, on the use of Ka-band. Two days are dedicated to technical presentations followed by a day dedicated to plant visits sponsored by Italian Industry and featuring satellite manufacturing facilities and ground installations.
The technical presentations will be given by invited speakers involved in the on-going operations of the Ka-band systems, by experts in the field of spectrum regulations and by representatives of the companies that have announced future Ka-band systems.
