摘要： A distributed antenna array with a centralized data hub for determining the presence and location of RF tags has been disclosed. This antenna array centralizes electronics and distributes the RF to zones in a facility to greatly reduce the expense of recurring components for monitoring RF tags. A single BRT/hub with multiple antennas attached to transmit and receive ports is used to cover an entire facility. Large facilities are covered by a small number of the BRT/hub combinations. The BRT/hub has transmit antennas coupled thereto, preferably by co-axial cable, that transmit signals to a portion or all of the RF tags and all or a portion of them modulate and reflect the RF signal to a particular receiving antenna. The receiving antenna then returns the RF signal with tag data to the BRT/hub, preferably by co-axial cable. Also disclosed is an RF backscatter tag that cleanly switches a resonant aperture antenna on and off, thereby greatly increasing the mark-to-space ratio of the backscatter data. This enables tags to be detected by the BRT at much greater distances.

摘要： An advertising compliance monitoring system is provided that includes a backscatter tag affixed to a sign or marketing material or shopper ID card, the tag communicating with a backscatter reader on a periodic basis. The tag includes a memory for storing tag data, a transmitter and a receiver. The tag uses sleep modes to conserve power. The tag transmits tag data to a reader automatically on a periodic basis or upon an event. The tag data includes an identification number used to identify the tag associated with a particular sign, price, marketing material or shopper, status data (e.g., delivered, displayed), and time and date information. This data is processed by a central server to determine compliance with and/or exposure to a particular advertising program.
