Abstract
Power consumption management for a radio frequency identification (RFID) reader for a radio frequency (RF) transponder system. The RF system includes an RFID device and a host. The RFID reader includes an RFID controller, an excitation signal transmitter, a response signal receiver, an optional RFID device detector, a host interface input/output, and a user interface. The method includes establishing a first power consumption level for the RFID reader, establishing a second power consumption level that is different from the first, and changing between the first level and the second level. The difference between the first level and the second level is derived from at least one technique for power consumption management. A plurality of techniques are presented. Among the potential benefits to reduced power consumption are increased energy efficiency and reduced radiated emissions. The option of choosing between power consumption levels presents unique opportunities in system design, implementation, and operation.
