Direct satellite broadcasting systems in Italy
Abstract
Generic and specific features of the planned Italian five-channel direct broadcast satellite system (DBS), scheduled for operation in the 1990s, are outlined. The channels will have a 27 MHz bandwidth with carrier signals in the 11.7-12.3 GHz range. The FM signals will be received by either outdoor antennas or UHF-VHF televisions. An SNR of 33 dB is projected. Ground-based antennas will be 90-220 cm in diameter, depending on their location relative to the center of the coverage zone. The Italian system will seek to bypass cable networking, which will require individually-modified television receivers. The necessary modification will need to be low cost to spur the market interest in the DBS. However, a compromise may be possible by using existing ground-based transmission facilities as relays for the satellite signals.
