1. A wireless batch calibration apparatus, comprising:

  • a wireless transceiver wirelessly connected to a reference apparatus and a plurality of to-be-calibrated devices in a calibration area, to receive a reference signal of the reference apparatus and a to-be-calibrated signal of each to-be-calibrated device;

    a processor circuit coupled to the wireless transceiver to calculate a compensation value of each of the to-be-calibrated devices according to the reference signal and the to-be-calibrated signal, to generate a compensation polynomial according to the compensation value and a calibration precision of each to-be-calibrated device, and to establish a calibration table to write the compensation polynomial of each of the to-be-calibrated devices and a setting bit back to each to-be-calibrated device; and

    a storage circuit coupled to the processor circuit to store the calibration table;

    wherein the calibration table comprises a field of MAC addresses, a field of signal parameters, a field of compensation polynomials and a field of complete calibrations.
