摘要: The wireless channel of the wireless communication system is selectively disrupted or interfered with based on the logical states of the data to be transmitted by an electronic device having no wireless data signal transmitting circuitry. A host device transmits a query packet which includes a header and a series of sub-frames to be received by a receiving device. As each sub-frame is transmitted, the electronic device can selectively disrupt the wireless channel by changing its characteristics such that the receiving device can no longer decode that sub-frame based on channel estimation from the header of the frame. Wireless channel disruption occurs in response to a specific state of the bit of data of a message to be communicated by the electronic device. The receiving device then issues a status reply to the host device indicating which sub-frames are decodable and which sub-frames are undecodable based on the initial channel estimation. The host device decodes the status reply to extract the message.
