FIELD: radio engineering, communication.SUBSTANCE: invention relates to a method and system for dynamic adjustment of radiofrequency parameters of a multi-frequency label, as well as a multi-frequency label. Through the present invention, the multi-frequency label can be adapted to different interaction objects and meet the requirements of different service functions. To this end, the system comprises a multi-frequency label and an interaction object, where the multi-frequency label includes: a carrier detection module, a main control module and N communication modules, where N is an integer greater than or equal to 2, and each communication module works on different frequency bands. The method is used during communication between the multi-frequency label and the interaction object, the method involving: the interaction object transmitting a negotiation request on the predetermined frequency band, the request at least carrying identification information and radiofrequency parameter information of the frequency band to be negotiated; the multi-frequency label receiving the negotiation request on the predetermined frequency band, and adjusting the radiofrequency parameters of the frequency band to be negotiated according to the content carried by the negotiation request.EFFECT: through the present invention, radiofrequency state can be adjusted according to the application scene, thereby reducing power consumption as much as possible.12 cl, 4 dwg |
