5세대 이동통신시스템을 위한 28 GHz 초고주파 대역 실내 채널 측정 및 전파 환경 분석

This paper presents analyses of the feasibility for the 28 GHz band with a comprehensive overview of the important channel parameters. A channel sounder system with a time-synchronization scheme is introduced, and the channel measurements are conducted in an in-building environment similar to a small shopping mall, especially NLoS positions. Furthermore, the path loss and channel modeling parameters are successfully obtained and analyzed.
