1 THE JOURNAL OF KOREAN INSTITUTE OF ELECTROMAGNETIC ENGINEERING AND SCIENCE Oct.; 25(10), ISSN (Print) ISSN X (Online) An Socio-Economic Effect Analysis of Using Open Spectrum in Korea 박석지 박덕규 김창주 강영흥 Seok-Ji Park Duk-Kyu Park* Chang-Joo Kim** Young-Heung Kang*** 요약,., GHz 2,605 MHz,., WiFi, DSRC, M2M, IoT RFID/USN. Abstract In this paper, we analyze the telecom services and their socio-economic effect of using open spectrum, which is to access sharing spectrum. For this, we suggest a concept and a classification of open spectrum as spectrum access model and make a survey for analyzing the socio-economic effect of spectrum, 2,605 MHz which is candidated for sharing between Hz in Korea. From survey results, we propose Mobile Telecommunications Assist Service and WiFi as the most effective services and Smart Car Service and M2M, IoT, and RFID/USN Service as the effective services to open spectrum. Key words: Socio-Economic Effect, Open Spectrum, Classification of Open Spectrum, Sharing Spectrum, Spectrum Access Model. 서론 GHz,.,., SNS, Off Loading, (R&D)(ICT).

It could enable innovative services, reduce prices, foster competition, create new business opportunities, and bring our communications policies in line with our democratic ideals.
