Coexistence analysis between intelligent transport systems and wireless multi-gigabit service in 60GHz bands

摘要

As information provided by intelligent transport systems is expanded to 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 utilized by the wireless multi-gigabit service. For the safe utilization of the frequency band, mutual coexistence between the intelligent transport systems and the wireless multi-gigabit service analysis is required.In this paper, the coexistence between the two services in the 60GHz band is analyzed. First, the international specifications and characteristics of the wireless multi-gigabit service and intelligent transport systems in 60GHz are investigated. Furthermore, protection distances between the two services in various application scenarios are analyzed based on the minimum coupling loss under the interference criterions of the interference to the noise ratio and the carrier to the interference ratio.
