본 논문에서는 RFID Gen2 프로토콜을 기반으로 단일 리더 환경에서 충돌 회피 방법인 FS-Aloha를 이용하여 태그 수가 증가함에 따라 Inventory Round과정을 거쳐 EPC값을 얻기까지의 인식시간 변화를 시뮬레이션으로 추정하였다. 그 결과 태그가 100개, 300개, 500개일 때 각각 0.09초, 0.30초, 0.49초로 추정되며, 이는 Gen2의 fast 모드에서 초당 1000개의 태그인식률을 만족 시키므로 본 지 실험 결과의 근거가 된다.

Purpose - Korean firms have entered the Mongolia, the world’s top 10 resource rich country with huge market potential, since the diplomatic relations between Korea and Mongolia were established in 1990, but little is known about Korean firms’ entry strategy in the Mongolian market. With this background, this study aims to investigate the seven cases of Korean firms doing business in Mongolia (SK Telecom, Samsung S1, T-Money, E1 Energy, Cafe Bene, E-Mart, and CU). Methodology - this study is based on numerous primary and secondary data about the Mongolian market, as well as Korean firms in Mongolia. Findings - the following three implications were derived from our case analysis: first, when entering into Mongolia, a thorough analysis of political and social risks and a good understanding of institutional voids should be preceded. Second, for this reason, entering through cooperation with local partners, such as joint ventures or franchising, is expected to increase the possibility of success. Third, unlike in the early days of Korean firms in Mongolia, the business environment in Mongolia has become more stable and predictable, and a friendly atmosphere for Koreans and Korean firms is forming, increasing the possibility of success and settlement of Korean firms. Research implications - this study contributes to extant literature by providing more systematic research on Korean firms in Mongolia and by presenting practical implications through the analysis of success and failure cases of Korean firms in the Mongolian market.
