    摘要： In accordance with the preferred embodiment and alternative embodiments of the invention, RFID network control devices (RNCDs) are provided wherein RFID traffic signals from any one of multiple RFID readers may be routed to any of the RFID antennas coupled to the RNCD. Each reader coupled directly or indirectly to the RNCD, either through its own action or the action of the external host controller managing the reader, may issue commands to the RNCD, over the same cable used to carry RFID traffic signals, and cause the RNCD to set its internal switch configuration such that a channel is established for RFID traffic signals between that reader and a particular RFID antenna coupled to the RNCD. This may include commands from the reader or external host controller which place other intervening RNCD units in a bypass state so as to establish the required communications channel with a minimum of signal strength loss.
