Abstract

A method for wireless communication by a wireless communication device is described. The method includes receiving geographic location information. The method also includes querying a geographic location tuning database for tuning parameter values corresponding with the geographic location information. The method further includes determining one or more tuning parameters to change based on the tuning parameter values. The method additionally includes adjusting an antenna for inductively coupled communication with a reader device according to the determined tuning parameters.

adjusting an antenna for inductively coupled communication with a reader device according to the determined tuning parameters.

2. The method of claim 1, wherein the geographic location information is received in at least one of a Global Positioning System (GPS) signal, a wireless wide area network (WWAN) signal, or a wireless local area network (WLAN) signal.

3. The method of claim 1, wherein the geographic location information is received in a non-standardized message sent by the reader device.

4. The method of claim 3, wherein the non-standardized message includes geographic location coordinates of the reader device.

5. The method of claim 3, wherein the non-standardized message includes a unique signature associated with the reader device from which the geographic location information of the reader device is determined.

6. The method of claim 3, wherein the non-standardized message is received in response to sending a poll response to the reader device, wherein the non-standardized message is sent using a near-field communication (NFC) technology identified by the poll response.

7. The method of claim 6, wherein the non-standardized message comprises a packet that includes a command code byte that identifies the packet as a non-standardized packet from the reader device, one or more bytes that include the geographic location information, and one or more bytes with cyclic redundancy check information for the identified NFC technology.

8. The method of claim 3, further comprising sending a non-standardized response to the reader device indicating support for antenna tuning based on the geographic location information.

9. The method of claim 8, wherein the non-standardized response comprises a packet that includes a command code byte that identifies the packet as a non-standardized packet from the wireless communication device, one or more bytes that include an acknowledgment (ACK) response, and one or more bytes with cyclic redundancy check information for the identified NFC technology.

10. The method of claim 1, wherein the geographic location information is received via a combination of a GPS signal and a non-standardized message, wherein the GPS signal is used by default to obtain the geographic location information, and the non-standardized message is used to obtain the geographic location information if the GPS signal is not available.

11. A wireless communication device, comprising:
