Determining the state of a station in a local area network

1. A method of determining the state of a station in a wireless local area network, wherein the state of the station indicates whether the station has authenticated and/or associated with an access point in the wireless local area network, the method comprising: receiving transmissions exchanged between the station and the access point using a detector located adjacent to the station, wherein the transmissions are exchanged over the wireless local area network; analyzing the received transmissions to determine the state of the station and determining the state of the station based on the analyzing, wherein the state of the station at least indicates whether the station is authenticated to the access point.

2. The method of claim 1 , wherein analyzing comprises: examining a received transmission; and determining an indicative state of the station associated with the received transmission.

3. The method of claim 1 , wherein the transmissions exchanged between the station and the access point comply with an extensible authentication protocol over local area networks (EAPOL) protocol.

4. The method of claim 1 , wherein the state of the station further indicates whether the station is associated with the access point.

5. An apparatus for determining the state of a station in a wireless local area network, wherein the state of the station indicates whether the station has authenticated and/or associated with an access point in the wireless local area network, the apparatus comprising: a detector configured to: receive transmissions exchanged between the station and the access point when the detector is located adjacent to the station; analyze the received transmissions to determine the state of the station; and determine the state of the static based on the analyzing, wherein the state of the station at least indicates whether the station is authenticated to the access point.

6. The apparatus of claim 5 , wherein the transmissions exchanged between the station and the access point comply with an extensible authentication protocol over local area networks (EAPOL) protocol.

7. The apparatus of claim 5 , wherein the detector is configured to receive transmissions by: scanning a plurality of channels used in the wireless local area network, wherein the station is rebooted if no transmissions are received during a scan of the plurality of channels.

8. The apparatus of claim 5 , wherein the state of the station further indicates whether the station is associated with the access point.

9. A computer-readable storage medium containing computer executable code to determine the state of a station in a wireless local area network, wherein the state of the station indicates whether the station has authenticated and/or associated with an access point in the wireless local area network, by instructing a computer to operate as follows: receiving transmissions exchanged between the station and the access point; analyzing the received transmissions to determine the state of the station; and determining state of the station based on the analyzing, wherein the state of the station at least indicates whether the Station is authenticated to the access point.

10. The computer-readable storage medium of claim 9 , wherein the transmissions exchanged between the station and the access point comply with an extensible authentication protocol over local area networks (EAPOL) protocol.

11. The computer-readable storage medium of claim 9 , wherein receiving comprises: scanning a plurality of channels used in the wireless local area network, wherein the station is rebooted if no transmissions are received during a scan of the plurality of channels.

12. The computer-readable medium of claim 9 , wherein the state of the station further indicates whether the station is associated with the access point.
