RFID READERS SYSTEMS AND METHODS FOR EARLY HOPPING OUT OF A FREQUENCY CHANNEL IN THE PRESENCE OF RF INTERFERENCE

摘要

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).
