First Claim
Patent Images
1. An RFID tag comprising:
- a decoder operable to decode a first wireless signal received subject to a first reception bandwidth setting; and
a selector switch operable to select, responsive to the first decoded signal, one of a second reception bandwidth setting and a third reception bandwidth setting different from the second reception bandwidth setting, such that the decoder is operable to further decode a subsequently received second signal subject to the selected reception setting.

Abstract
RFID tags, tag circuits, and methods adapting the reception bandwidth. A tag has a decoder for decoding a first received wireless signal subject to a reception bandwidth setting. The tag also has a selector switch for transitioning to a different setting, such as by switching to using a different filter. A subsequently received second signal is decoded subject to the new reception bandwidth setting.
