RFID tag dynamically adjusting clock frequency |
摘要 |
RFID tags are configured to adjust their clock frequency in order to meet predefined limits for reply frequencies to conserve tag power. A deviation of computed tag reply frequency from a reader commanded reply frequency is used to determine an adjustment to the tag clock frequency. The tag clock frequency may be adjusted during backscatter and restored once backscattering is completed. |
