WAVE system architecture design in urban area

This paper describes WAVE (Wireless Access in Vehicle Environment) system design especially for Urban area. WAVE technology is currently is developing in worldwide and there are standardizations under IEEE, ETSI (European Telecommunication Standard Institutes), and ARIB (Association of Radio Institutes and Business) in Japan. WAVE technology is based on wireless LAN (Local Area Network) technology in IEEE802.11 series and it is studied as IEEE802.11p. The frequency band is assigned in 5.9GHz in Europe and north America. In Japan, there are 5.8GHz and next 700MHz plan. In general WAVE radio range is not so much long distance such as mobile phone but achieves high speed access network in dedicated short distance, therefore it is also called DSRC (Dedicated Short Range Communications). Therefore authors describe how to use WAVE and mobile communication architecture for vehicular wireless communications, especially in urban area.
