a transceiver coupled to the processor and the antenna for transmitting the hashed ID wirelessly within a physical layer frame/packet via the antenna.

6. The access point device in accordance with claim 5 wherein the processor is further operable for:

inserting the hashed ID within a signal field of a preamble in the physical layer frame/packet.

7. The access point device in accordance with claim 5 wherein the second number of data bits is less than or equal to 10.

8. The access point device in accordance with claim 5 wherein the ID is a BSSID that comprises at least 46 bits.

9. A wireless user station, comprising:

an antenna;

a transceiver coupled to the antenna and operable for receiving a hashed ID wirelessly within a physical layer frame received at the antenna, the hashed ID uniquely identifying a remote access point device and a channel of the remote access point device; and

a processor coupled to the transceiver, the processor operable for:

generating an expected hashed ID by:

combining a desired ID with channel information of a predetermined channel to generate combined ID/channel information, the combined ID/channel information comprising a first number of data bits, wherein the combining comprises combining the desired ID with the channel information using an exclusive-OR function, and

applying a hashing function H to the combined ID/channel information to generate the expected hashed ID, the expected hashed ID comprising a second number of data bits and less than the first number of data bits,

wherein the received hashed ID is at least a one of a received hashed SSID and a received hashed BSSID, the combined ID/channel information is at least a one of a combined SSID/channel information and a combined BSSID/channel information, and the expected hashed ID is a one of an expected hashed SSID and an expected hashed BSSID,

comparing the received hashed ID to the expected hashed ID, and

initiating an action based on a result of the comparison.

10. The wireless user station in accordance with claim 9 wherein the processor is further operable for:

retrieving the received hashed ID within a signal field of a preamble in the physical layer frame.

11. The wireless user station in accordance with claim 9 wherein the second number of data bits is less than or equal to 10.

12. The wireless user station in accordance with claim 9 wherein the desired ID is a desired BSSID comprising at least 46 bits.

13. The wireless user station in accordance with claim 9 wherein the wireless user station functions in compliance with one or more versions of an IEEE 802.11 standard.

14. A method for generating a unique identifier for a wireless access point within a wireless network, the method comprising:

combining a BSSID of the wireless access point with channel information of the wireless access point using an exclusive-OR function to generate combined BSSID/channel data;

applying a hashing function H to the combined BSSID/channel data to generate a hashed BSSID, the combined BSSID/channel data having a first number of bits comprising at least 48 bits, the hashed BSSID having a second number of bits which are less than the first number of bits of the combined BSSID/channel data; and
