1. A radio frequency identification (RFID) system comprises:

  • an RFID reader including;

    a reader processing module to encode outbound RFID data to produce outbound RFID encoded data and to decode inbound RFID encoded data to produce inbound RFID data;

    an RFID transceiver coupled to convert the outbound RFID encoded data into an outbound RF RFID signal and to convert an inbound RF RFID signal into the inbound RFID encoded data; and

    a reader radio frequency (RF) bus transceiver;

    an RFID tag including;

    a power recovery module coupled to produce a supply voltage from the outbound RF RFID signal and to produce a received RF RFID signal;

    a tag processing module coupled to recover the outbound RFID data from the received RF RFID signal and to generate tag RFID data; and

    transmit section coupled to convert the tag RFID data into the inbound RF RFID signal;

    a network connection module coupled to provide connection to a network, wherein the network connection module includes a network connection RF bus transceiver, wherein the reader RF bus transceiver exchanges at least one of the inbound RFID data and the outbound RFID data with the network RF bus transceiver via an RF bus.
