Utility
Controlling RFID tag population backscatter characteristics
24 Oct 23
RFID tag ICs in a population can adjust the impedance values used to backscatter-modulate reply signals to increase the distribution or spread of backscattered signal parameters, thereby facilitating the recovery of collided tag replies.
