RFID Read Range Calculator

Calculate RFID read range based on reader power, tag sensitivity, and antenna gain.

리더기 TX 출력 (dBm)

안테나 이득 (dBi)

케이블 손실 (dB)

태그 감도 (dBm)

주파수 (MHz)

환경 요소

예상 읽기 범위

(0.0 ft)

프리이스 전송 공식

R = (c / 4πf) × √(EIRP / P_tag) × env_factor

여기서 EIRP = P_tx + G_ant - L_cable (선형 스케일)
