发明名称 Portable encoded information reading terminal configured to adjust transmit power level
摘要 A system and method of adjusting the transmission strength emitted by an integrated RFID reader. The system may stores the location of the RFID when moved proximate to an object as a point of origin. When the RFID reader moves relative to the point of origin, the system may determine the distance of the RFID reader from the point of origin and may adjust the power level of the RFID reader relative to this distance.

主权项 1. A method of adjusting a transmission strength emitted by an RFID reader, the method comprising: scanning, by the RFID reader, a space for predetermined period of time at a first power level; storing, in memory of the RFID reader, a first location of as a point of origin; changing, by the RFID reader, the power level of the RFID reader to a second power level based on a distance of the RFID reader from the point of origin after the RFID reader is moved from the point of origin; and scanning, by the RFID reader, the space for predetermined period of time at a second power level.
