2 . The method of claim 1 , wherein automatically converting, independent of digital signal processing, the received request comprises automatically converting the receive request from a first frequency to a second frequency independent of digital signal processing.

3 . The method of claim 2 , wherein the first frequency comprises 915 MegaHertz (MHz) signals.

4 . The method of claim 1 , wherein the second frequency 5.9 GigaHertz (GHz) signals.

5 . The method of claim 1 , wherein automatically converting the receive request from a first frequency to a second frequency comprises:

demodulating the received request from a first frequency to a baseband signal; and

directly modulating, independent of digital signal processing, the baseband signal to a second frequency to generate the converted request.

6 . The method of claim 1 , wherein automatically converting, independent of digital signal processing, the received request comprises automatically converting the receive request from a first RFID protocol to a second RFID protocol independent of digital signal processing.

7 . The method of claim 1 , wherein the first RFID protocol comprises Electronic Product Code (EPC) GEN 2.

8 . The method of claim 6 , wherein the second RFID protocol comprises Dedicated Short-Range Communications (DSRC).

9 . The method of claim 1 , wherein a passive transceiver receives the request and transmits the converted request transparent to the RFID reader.

10 . The method of claim 1 , further comprising:

receiving a reply from the RFID tag compatible with the second RFID protocol;

converting the reply to a form compatible with the RFID reader; and

transmitting the converted reply to the RFID reader.

11 . The method of claim 1 , further comprising presenting a slave transceiver as an RFID reader of the first type.

12 . The method of claim 1 , further comprising:

receiving a request from the RFID reader to update a communication frequency of transmitted signals; and

automatically updating a modulation frequency in response to at least the request.

13 . An RF converter, comprising:

a receiver configured to receive a request from a Radio Frequency Identification Device (RFID) reader configured to communicate with a first type of RFID tag;

a converting module configured to automatically convert, independent of digital signal processing, the received request to a request compatible with a second type of RFID tag different from the first type of RFID tag; and

a transmitter configured to transmit the converted request to an RFID tag of the second type of RFID tag.

14 . The converter of claim 13 , the converting module further configured to automatically convert the receive request from a first frequency to a second frequency independent of digital signal processing.

15 . The converter of claim 14 , wherein the first frequency comprises 915 MegaHertz (MHz) signals.

19 . The converter of claim 13 , wherein the first RFID protocol comprises Electronic Product Code (EPC) GEN 2.

20 . The converter of claim 18 , wherein the second RFID protocol comprises Dedicated short-range communications (DSRC).

21 . The converter of claim 13 , wherein a passive transceiver receives the request and transmits the converted request transparent to the RFID reader.

22 . The converter of claim 13 , further comprising:

the receiver further configured to receive a reply from the RFID tag compatible with the second RFID protocol;

the converting module further configured to convert the reply to a form compatible with the RFID reader; and

transmitter further configured to transmit the converted reply to the RFID reader.

23 . The converter of claim 13 , wherein presenting a slave transceiver as an RFID reader of the first type.

24 . The converter of claim 13 , further comprising:

the receiver further configured to receive a request from the RFID reader to update a communication frequency of transmitted signals; and

the converting module further configured to automatically update a modulation frequency in response to at least the request.

25 . A system, comprising:

a means for receiving a request from a Radio Frequency Identification Device (RFID) reader configured to communicate with a first type of RFID tag;
