Method for differentiating between data signals and interference signal, involves receiving signals of radio frequency identification tags, particularly signal strength indicator signal by multiple antennas

摘要

The method involves receiving signals of Radio frequency identification (RFID)tags (Tag1,Tag2), particularly signal strength indicator signal by multiple antennas of a radio frequency identification gate. The period under observation is determined. The difference between the highest value and the lowest value of the signal strength of each signal curve for each transmitter of each antenna, is determined. An independent claim is also included for a radio frequency identification gate with an evaluation circuit.
