1. a RFID traffic model air interface parameter testing method, adopts assisted tag test read write lineWith the air interface parameters of tested label, read write line and tested label composition system, read write line and be placed inTested label assisted tag identical or suitable position forms system, and two systems include traffic model, instituteStating assisted tag is electronic tag, and described assisted tag power is adjustable, described assisted tag antenna external andCan test transmitting-receiving level at antenna feed point, tester detects the power of assisted tag, read write lineLevel value, obtains air interface parameters, and air interface parameters is according to the power level of assisted tag, read write lineValue directly or indirectly calculates, and described air interface parameters comprises that the write signal of tested label receives sensitiveThe read signal receiving sensitivity of degree, tested label, the receiving sensitivity of read write line, forward path are propagated and are damagedConsumption, and reverse path propagation loss;

  • The write signal receiving sensitivity of described tested label is that tested label is carried out read write line and write instruction and completeThe minimum received power level of write operation;

    The read signal receiving sensitivity of described tested label is by markSign the minimum received power level that execution read write line reading command completes read operation;

    The reception of described read write lineSensitivity is the minimum reception that read write line can correctly be identified electronic tag return data information while realizing read operationPower level;

    Described forward path propagation loss is negative to the conduct on label signal transfer path by read write lineThe loss of gain;

    Described reverse path propagation loss is to the conduct on read write line signal transmission path by labelThe loss of negative gain;

    Described assisted tag;

    Have self-powered ability, assisted tag can provide the transmitting power larger than tested label;

    And,Assisted tag is identical with the modulation parameter of tested label;

    And,Assisted tag is used Standard Symmetric Multivariate dipole antenna.
