1. A computer-implemented method of managing inventory, comprising: receiving, at an antenna operatively coupled to a radio-frequency identification (RFID) reader, product identification information encoded in a first RF signal transmitted by a plurality of RFID tags associated with a plurality of first products at a first location; receiving, at the antenna, product identification information encoded in a second RF signal transmitted by one or more RFID tags associated with one or more second products at the first location; analyzing, by a processor, the first RF signal to identify a first product characteristic common to the plurality of first products based on the product identification information encoded in the first RF signal; analyzing, by the processor, the second RF signal to identify a second product characteristic different from the first product characteristic and associated with the one or more second products based on the product identification information encoded in the second RF signal; and identifying, by the processor, a data pattern from the first product characteristic and the second product characteristic, the data pattern identifying that the plurality of first products comprise a majority of all products at the first location based on the first product characteristic, and indicating that the one or more second products are incorrectly co-located at the first location with the plurality of first products based on the difference between the second product characteristic and the first product characteristic.
