LOW COST, WIDE AREA RFID SYSTEM
First Claim
1. A system comprising:
- a plurality of antennas deployed in a location, wherein each antenna of the plurality of antennas is configured to receive a signal indicative of a tag proximate to the antenna;
a memory;
a processor configured to;
process tag detection signals that are based on the received signals, wherein the processing comprises;
selectively storing tag detection signals in the memory; and
identifying an event related to presence of a tag at the location based on a plurality of tag detection signals, the plurality of tag detection signals comprising at least one stored tag detection signal; and
a transmitter configured to transmit a message indicating the event over a wide area network to a server.

Abstract
Techniques for radio-frequency identification systems include sensor systems having a sensor unit and one or more sensors and a server. The sensor system includes one or more antennas at a location configured to receive signals from a tag proximate to an antenna and a processor configured to process tag detection signals based on the received signals. The processing may include selectively storing tag detection signals received from one or more antennas and identify an event related to the presence of a tag proximate to an antenna at the location. Sensor system may include a transmitter configured to transmit a message indicating the event over a network to a server. The server may be configured to process the message by analyzing a feature of the signals related to the event. The analysis may evaluate an adjustment of a configuration parameter used to operate an antenna. The configuration parameter may be updated by the server, and the server may transmit a message indicating the configuration parameter to the sensor system.
