A study on the coexistence analysis of intelligent transport systems in 60GHz bands

EasyChair Preprint 449

Abstract

As information provided by intelligent transport systems is expanded from simple traffic information to high-resolution maps for autonomous driving and various infotainment services, the need for additional frequency allocation is increasing. Therefore, in Europe, the 63-64GHz band is allocated in addition to the existing 5.9GHz. However, the 60GHz band is used for unlicensed services and the wireless multi-gigabit service is already utilized in the frequency band. For the safe utilization of the frequency band, coexistence analysis between the intelligent transport systems and the wireless multi-gigabit service is required. In this paper, the coexistence between the two services in the 60GHz band is analyzed assuming the case that the same millimeter wave frequency as Europe is allocated for intelligent transport systems in various countries. First, the international specifications and characteristics of the wireless multi-gigabit service and intelligent transport systems are investigated. Furthermore, protection distances between the two services in various application scenarios are analyzed based on the minimum coupling loss. The results show that a careful consideration of frequency allocation for ITS is required for the safe coexistence. The coexistence analysis presented in this paper is expected to be used as a guideline in millimeter wave frequency allocation for ITS.
