Abstract

Various embodiments of the present disclosure identify radio frequency identification tag(s) and/or location(s) thereof. Embodiments may perform such identification utilizing any number of antennas configured at various power levels and/or frequency channels, such as by incrementing and/or decrementing the power level of each antenna and measuring a number of tag reads at interval for each antenna. Confidence scores for each antenna may be generated and compared. Some example embodiments initiate an interrogation command associated with a RFID tag, cause activation of a plurality of antennas at a plurality of transmit power levels, identify a count of tag reads associated with each antenna, and determine a tag location associated with the RFID tag based on the count of tag reads for each antenna.
