Abstract

An access port has an RF tag associated therewith (e.g., physically incorporated into the access port), wherein the RF tag includes configuration information. A mobile unit having an RF tag reader associated therewith sends a probe request and reads the configuration information from the RF tag. The RF tag may include, for example, information traditionally incorporated into an IEEE 802.11 probe response or beacon. The tag may include, for example, non-real-time configuration information, such as capabilities of the access port, data rates, and the like.

Claims

1. A method for associating a mobile unit with an access port in a wireless network, the method comprising:

providing a RF tag coupled to the access port, wherein the RF tag includes configuration data;

scanning for RF tags in the vicinity of the mobile unit; and

reading the configuration data from the RF tag.

2. The method of claim 1, wherein reading the configuration data includes reading information related to configuration of the access port.

3. The method of claim 1, wherein reading the configuration data includes reading information related to configuration of the wireless network.

4. The method of claim 1, wherein reading the configuration data includes reading information that at least partially comprises a probe response from the access port.

5. The method of claim 4, wherein the configuration data comprises at least a portion of an IEEE 802.11 probe response.

6. The method of claim 1, further including updating the configuration data on the RF tag.

7. The method of claim 1, wherein the access port is configured to send a probe response that includes an instruction to the mobile unit to perform the step of reading the configuration data from the RF tag.

8. The method of claim 7, wherein the configuration data includes a substantially non-real-time component of an IEEE 802.11 beacon.

9. A wireless network system comprising:

an access point having an RF tag associated therewith, the RF tag including configuration information, the access point configured to send a probe response in response to a probe request; and

a mobile unit having an RF tag reader associated therewith, the mobile unit configured to send the probe request and to read the configuration information from the RF tag.

10. The system of claim 9, wherein the configuration data includes information related to configuration of the access port.

11. The system of claim 9, wherein the configuration data includes information related to configuration of the wireless network.

12. The system of claim 9, wherein the configuration data comprises a subset of an IEEE 802.11 probe response.

13. The system of claim 9, wherein the access port is configured to update the configuration data on the RF tag.

14. The system of claim 9, wherein the probe response includes an instruction to the mobile unit to perform the step of reading the configuration data from the RF tag.

15. The system of claim 9, wherein the probe response includes at least one non-real-time parameter of an 802.11 beacon.

16. An access port having an RF tag coupled thereto, wherein the RF tag includes configuration data related to the access port.

17. The access port of claim 16, wherein the configuration data includes a subset of an IEEE 802.11 probe response.

18. The access port of claim 16, wherein the access port is configured to send a probe response that includes an instruction to read the configuration data from the RF tag.

19. The access port of claim 16, wherein the RF tag is selected from the group consisting of active tags, passive tags, and semi-active tags.
