Abstract :
This paper describes WAVE (Wireless Access in Vehicle Environment) system design especially for UHF frequency band. Especially 700MHz band is currently used for analog TV terrestrial service in the world and it is going to be terminated soon or done in the world. Japan will terminate 700MHz band analog TV in July 2011 and it is going to assign new application system from 2012. In terms of WAVE system, IEEE802.11p standard is available in currently world wide standardization activities and it is focused on 5.9GHz frequency band. However 700MHz band has more technology advantage not only longer range communication but also hidden vehicles access such as in urban area. In Japan, MIC (Ministry of Internal Affaires and Communications) is going to assign ITS (Intelligent Transport System) frequency at 720MHz band with 10MHz bandwidth and started several field tests. In order to use 700MHz technology advantage, authors propose optimized 700MHz WAVE system architecture design and it will be useful for future standardization.
