RFID DENSE READER/AUTOMATIC GAIN CONTROL
First Claim
1. A method for increasing accuracy of locating a media enhanced shopping cart comprising:
- determining a location of a cart based on a proximity scan of one or more RFID tags using one or more RFID antennas and an RFID reader;
detecting when a dense reader mode of operation is indicated; and
adjusting sensitivity of the RFID antennas such that RFID tags anticipated as being included in the proximity scan are read and RFID tags anticipated as excluded from the proximity scan are not read.

Abstract
A media enhanced shopping cart system comprises a shopping cart comprising a frame, a basket, a handle, a base tray, a plurality of wheels, a read component for performing a proximity scan of the shopping cart, a locationing component for determining a location of the shopping cart within a store based on the scan, and a display component for displaying at least one advertisement for a product based on the location of the shopping cart within the store, wherein the locationing component is further operable to determine a location of the product within the store relative to the shopping cart based on the scan, and wherein the display component is further operable to display an indication of the location of the advertised product relative to the location of the shopping cart.

16. A method for increasing accuracy of locating a media enhanced shopping cart comprising:
-
determining a location of a cart based on a proximity scan of one or more RFID tags using one or more RFID antennas and an RFID reader; accessing a database of known locations of RFID tags to determine which tags of the RFID tags read in the proximity scan are anticipated as being included or excluded from the proximity scan; and adjusting sensitivity of the RFID antennas such that RFID tags anticipated as being included in the proximity scan are read and RFID tags anticipated as excluded from the proximity scan are not read. - View Dependent Claims (17, 18, 19, 20)
