초록
As an RFID interrogator transmitting a command depending on a collision situation and a control method thereof, the RFID interrogator includes a collision diagnosis unit that analyzes data of a received signal received during a receive time in correspondence with a transmitted signal from an RF communication unit that can transmit and receive signal to and from one or more tag, verifies whether or not a collision occurs in the received signal, and diagnoses a collision type depending on an analysis result of the data of the received signal; and a collision resolution unit that can retransmit a command to the tag through the RF communication unit depending on the collision situation on the basis of whether or not occurrence of the collision or not and the collision type that are received from the collision diagnosis unit.
