The transmitter is activated by the power source responsive to the receiver receiving a wake up command at a predetermined low frequency from the active RFID transceiver. An RFID transceiver includes an antenna, non-transitory computer-readable medium storing instructions and a transmitter to transmit low-frequency signals to RFID tags through the antenna. A processing device of the RFID transceiver can execute the instructions to insert a station identifier (ID) into the low-frequency signals that direct the RFID tags to retransmit the station ID, wherein the station ID identifies an approximate location of the RFID tags."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low-frequency receiving for radio frequency identification","description":"A radio frequency identification (RFID) tag includes a power source, a transmitter to transmit a unique identifier, and a receiver operatively coupled to the transmitter and to receive low-frequency s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9785806","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
