1 THE JOURNAL OF KOREAN INSTITUTE OF ELECTROMAGNETIC ENGINEERING AND SCIENCE Oct.; 25(10), ISSN (Print) ISSN X (Online) 700 MHz Analysis of Domestic and Foreign Frequency Demands for 700 MHz Band and Consideration for Building Public Integrated Radio Network 박덕규 Duk-Kyu Park 요약 DTV 700 MHz. 700 MHz,., 700 MHz, e-navigation. Abstract After DTV transition, frequency allocation to efficiently utilize 700 MHz band, which is remained as Digital Dividend, is in progress domestically and internationally. This paper investigates global frequency allocation of 700 MHz band and utilization of the band, and analyzes domestic wireless technology methods and requested frequency bandwidth by use. In addition, the paper suggests what needs to be considered in case of building public integrated radio network that focuses on disaster and safety network; the integrated radio network also includes railway network and e-navigation. Key words: 700 MHz, Public Integrated Radio Network, Disaster and Safety Network, Railway Network, e-navigation. 서론 DTV, 700 MHz 100 MHz. Digital Dividend,., APT.,, (,, e-navigation),.,, 2014 (ICT).
