Abstract: RFID readers (110), systems (100), and methods are provided for overcoming the effects of RF interference (128). While a system (100) is communicating in a channel, RF interference (128) is monitored. If it is low, then hopping to another channel is performed according to an ordinary decision. But if interference is high, then hopping out to another channel can be earlier than would be dictated by the ordinary decision under the same circumstances. The earlier hopping out can result in diminishing communication in channels with a lot of RF interference (128).

Abstract: RFID readers, systems, and methods are provided for overcoming the effects of RF interference. While a system is communicating in a channel, RF interference is monitored. If it is low, then the next channel to be hopped onto is chosen in an unbiased manner. But if interference is high, then the next channel to be hopped onto is chosen in a biased manner that disfavors at least one channel over another, in view of the detected interference. The choice of the next channel can thus result in diminishing communication in channels with a lot of RF interference.

Abstract translation: 为了克服RF干扰的影响，提供RFID阅读器，系统和方法。 当一个系统正在通道中通信时，会监测射频干扰。 如果它很低，那么将以无偏差的方式选择要跳到的下一个通道。 但是如果干扰很高，那么考虑到检测到的干扰，下一个要跳频的信道是以偏倚的方式选择的，这会使至少一个信道不利于另一个信道。 因此，选择下一个频道会导致信道中的通信量减少，从而产生大量的RF干扰。

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.
