This paper presents development of the transponder system which provides an accurate train position, especially for supporting 400km/h high speed train. Here, we analyzed an operating frequency band of the transponder system which can be interoperable with the Eurobalise system already installed in Korea railroad as to be used for the automatic train protection (ATP). By investigating the power frequency band and its data frequency band of the transponder system, we presents the adoptable frequency band for the developed transponder system. Additionally, through the real testbed using HEMU-430X, we evaluate its performance requirement and shows interoperable operation with the Eurobalise system.

Unmanned Aerial Vehicles (i.e., drone) are gaining a lot of interest from a wide range of application domains such as infrastructure monitoring and parcel delivery service. In those service scenarios, multiple UAVs are involved and should be reliably operated by so-called UAV management system. For that, we propose oneM2M standard based UAV management and control system which is specifically targeted at traffic management of low-altitude UAVs. In this paper, we include oneM2M platform architecture and its implementation for UAV management system in conjunction with UAV interworking procedure.

스마트시티를 구현하기 위해서는 다양한 ICT 기술이 필요한데, 도시의 다양한 객체로부터의 센싱, 상당량의 센서로부터의 무선 통신 기술, 센싱된 데이터를 수집/저장/분석하고 분석된 결과를 토대로 센서로의 제어, 시각화, 통계 제공 등이 있다. 본 논문에서는 도시의 다양한 데이터를 수용하여 데이터 기반의 실질적 스마트시티를 이룩하기 위하여 필요한 현 ICT 대표기술을 알아보고, 이를 어떻게 유기적으로 연동해야 하는지에 대해 기술한다.
