The VICS (vehicle information and communication system) and ETC (electronic toll collection) technologies, which are ITS (intelligent transport systems) services, have been made practical in recent years, and services that apply those technologies are steadily being developed in various fields. On the other hand, network services are becoming global in scope as a result of the rapid proliferation of Internet use. Amidst these trends, one development of the "automobile society" is that, by connection with a cell phone, the automobile has become an information terminal. The network service provision platforms, and particularly the wireless access platforms, include broadband communication networks, dedicated networks for special purposes, broadcast communication, etc. We believe that services will be developed that take advantage of the special features of each of these platforms and their mutually complementary nature. As various kinds of communication platforms for supporting ITS services, Hitachi is grappling with broadband communication services [cdma 2000 1xEV-DO (1x Evolution-Data Only)], HEO (highly-elliptical orbit satellite system) and DSRC (dedicated short-range communication system).
