Abstract
Methods, systems, and apparatuses for ways of locating tags are described. A power level of a RFID communication signal transmitted by a RFID device, such as a reader, is adjusted to hone in on a specific tag. For example, the power level may be decreased or increased, depending on the situation, to hone in on the tag. The RFID device may be repositioned to aid in further honing in on the tag. Transmitting RFID communication signals, adjusting transmit power levels, and repositioning the RFID device may be iterated as needed to hone in on the tag.
