강수 환경에서의 Passive Tag 인식거리 측정 시험

In the world, RFID technology system which detect and recognize object with non-connecting using wireless signal remotely is being widely used to many industrial areas for position detection. The RFID System is composed Tag, reader and antenna The RFID Tag can be classified active and passive Tag. Passive Tag are cheap than active Tag, but is essential to ensure reliability from developing RFID tags packaging because the performance degradation such as tag read range reduced by abiotic factors. Passive Tag are cheap than active Tag, but is essential to ensure reliability from developing RFID tags packaging because the performance degradation such as tag read range decreasing by abiotic factors such as snow, rain, fog and so on.. In the paper, the sticker-type commercial passive tag read range in the frequency bands 900~960MHz has been measured for utilize the train position detection in the precipitation.
