RFID Read Range Calculator

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

Daya TX Pembaca (dBm)

Gain Antena (dBi)

Rugi Kabel (dB)

Sensitivitas Tag (dBm)

Frekuensi (MHz)

Faktor Lingkungan

Jangkauan Baca Perkiraan

0.0 m

(0.0 ft)

Rumus Transmisi Friis

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

Di mana EIRP = P_tx + G_ant - L_cable (dalam skala linier)
