A Study on the TVWS Available Channels in the East Sea of Korea (Gangneung-Ulneung-Dokdo)

This paper describes the study in Korea to secure available frequency resources at sea among terrestrial DTV (Digital Television) broadcasting bands. Focusing on Gangneung, Ulleungdo, and Dokdo in the East Sea of Korea, the possibility of using TVWS (TV White Space) frequencies of DTV broadcast signals (470～698 MHz) was studied. According to the analyses, channel 39 (623 MHz) and channel 41 (635 MHz), can be used as TVWS available channels without interference with DTV in all nearby seas. Five channels 36 (605 MHz), 43 (647 MHz), 45 (659 MHz), 50 (689 MHz), and 51 (695 MHz), were analyzed to be available for TVWS frequencies on the east coast except Gangneung and nearby area.
