Wireless communications: Broadcasting system. An advanced CATV system with wireless distribution

Abstract

CATV (Community Antenna TV) has been started as a measure intended to improve the poor reception area since 1955 at the spa of Ikaho in Gunma prefecture. Recently CATV has come into the limelight as a multi program distributor and a new transmission media of the broadband Internet. The percentage of household CATV sets is 22 percent in 2000 in Japan. The wireless distributed CATV system is able to complement the wired system. It is serviceable in where the cable cannot lay, such as the area studded with houses or isolated island. In this paper, an advanced CATV system with wireless distribution is mentioned. The frequency band is the millimeter-wave band, because it has the characteristic of allowing broadband transmission and miniaturization of devices. The link budget of the test system using 60 GHz band is also described.
