Abstract-This paper discusses system and technology aspects crucial to the development of satellite communications at Ka band (20-30 GHz) and beyond. It surveys the evolution of Ka band geostationary Earth orbit (GEO) satellite communications until the present stage of development of systems for direct-to-user (DTU) provision of interactive multimedia services worldwide. Then it discusses the attenuation problem and main technical issues of this new technology. Finally, it provides a view on experiments and technological developments at extremely highfrequency (EHF) bands.

“…Shortcoming land-mobile systems based on satellite constellations will adopt feeder links (connection between satellites and radio-base) in K, bands (20/3Q GHz) 141; feasibility studies for systems using millimetre wavelengths also for the mobile-satellite links have been undertaken in the recent past and are still in progress [5]. Many different problems and different strategies (known as fading countermeasures) can be envisaged to counteract rain attenuation: site diversity, up-link power control, adaptive transmission rate:, back ups at lower frequency, etc.…”

The paper deals with the severe propagation problems that wiill be probably encountered in designing the future satellite communication systems in the Ka band and above and with some possible advanced solutions based on the knowledge of the local climatology. Within the very wide spectrum of new envisaged systems two ]particularly significant examples have been selected: the TV-sat at 22 GHz and the feeder-links at 20-30 GHz when site diversity configurations will be necessary as expected with low elevation orbiting satellites. As shown in the paper, by exploiting to the maximuIn extent the available meteorological informations, very effective fading and power-saving countermeasures can be envisaged.The enormous importance acquired by the satellite in some future t e l e c o~~~~c a~i o n systems like the direct TV broadcasting or the radio mobile is under the everybody's eyes; ong the various reasons of this s8uccess, the principal one undoubtly i s the ease to cover, with relatively IOW costs and in short time, very extended a e a s while keeping an e J ;~a o r d i n~ service flex ity. However, owing; to the greatly increased demand of tlransmission capacity (now and for the future), probl arise to cope with shortage of banwidth and orbital arcs, and with control of the EM interference and it is expected to become harder and harder in the next future.
