Abstract

A wireless communication system for use with a vehicle is disclosed. The communication system comprises a portable wireless device comprising a first manual interface device, the portable wireless device adapted to transmit an activation signal in response to manipulation of the first manual interface device, and an onboard wireless communication device for a vehicle. The onboard wireless communication device can be adapted to transmit Wi-Fi Protected Setup initiation signals in response to receiving the activation signal.

Claims

1. A wireless communication system comprising:

a portable wireless device comprising a first manual interface device, the portable wireless device adapted to transmit an activation signal in response to manipulation of the first manual interface device; and

an onboard wireless communication device for a vehicle, the onboard wireless communication device adapted to transmit Wi-Fi Protected Setup (WPS) initiation signals in response to receiving the activation signal.

2. The wireless communication system of claim 1, wherein the onboard wireless communication device further comprises a second manual interface device, and wherein the onboard wireless communication device is adapted to transmit WPS initiation signals in response to manipulation of the second manual input device.

3. The wireless communication system of claim 1, wherein the onboard wireless communication device is further adapted to transmit a notification signal in response to receiving a remotely-originating WPS initiation signal.

4. The wireless communication system of claim 3, wherein the portable wireless device further comprises a third manual interface device, and the portable wireless device is further adapted to transmit an acknowledgment signal in response to manipulation of at least one of the first and third manual interface devices.

5. The wireless communication system of claim 4, wherein the onboard wireless communication device is adapted to transmit a WPS response signal in response to receiving the acknowledgment signal.

6. The wireless communication system of claim 5, wherein the portable wireless device further comprises a feedback device, and the portable wireless device is further adapted to operate the feedback device in response to reception of at least one of the WPS notification signal and the acknowledgment signal.

7. The wireless communication system of claim 1, further comprising a wireless access point comprising a fourth manual interface device, and the wireless access point is further adapted to transmit a WPS response signal in response to manipulation of the fourth manual interface device.

8. The wireless communication system of claim 1, further comprising a wireless access point comprising a fourth manual interface device, the wireless access point is adapted to transmit the WPS response signal in response to reception of the WPS initiation signal.

9. The wireless communication system of claim 7, wherein the wireless access point is further adapted to transmit WPS initiation signals in response to manipulation of the fourth manual interface device.

10. A method of preparing secure communication between a vehicle and a wireless access point comprising:

receiving a wireless activation signal from a key fob associated with the vehicle; and

transmitting a Wi-Fi Protected Setup (WPS) initiation signal from the vehicle in response to reception by the vehicle of the wireless activation signal.

11. The method of claim 10, further comprising:

receiving the WPS initiation signal at a wireless access point; and

transmitting a WPS response signal from the wireless access point in response to receiving the WPS initiation signal.

12. The method of claim 10, further comprising transmitting the wireless activation signal from the key fob, wherein transmitting the wireless activation signal is responsive to manipulation of at least one button of the key fob.

13. The method of claim 12, wherein manipulation of at least one button of the key fob comprises activation of each of at least two buttons at different times.

14. The method of claim 12, wherein manipulation of at least one button of the key fob comprises activation of at least one of the buttons for at least one second.

15. The method of claim 12, wherein the key fob is adapted to transmit a signal requesting a vehicular action in response to a user pressing the at least one button.

16. A method of preparing secure communication between a vehicle and a wireless access point comprising:

receiving a wireless network security protocol initiation signal at the vehicle;

transmitting a notification signal from the vehicle in response to receiving the wireless network security protocol initiation signal;

receiving the notification signal at a key fob;

operating a feedback device of the key fob in response to the notification signal;

transmitting an acknowledgement signal from the key fob in response to manipulation of a manual interface device of the key fob;

receiving the acknowledgement signal at the vehicle; and

transmitting a wireless network security protocol response signal from the vehicle in response to receiving the acknowledgment signal.

17. The method of claim 16, wherein operating a feedback device comprises emitting an audible or visual signal from the key fob.

18. The method of claim 16, wherein manipulation of the manual interface device of the key fob comprises activation of at least one button of the key fob.

19. The method of claim 18, wherein manipulation of the manual interface device comprises engagement and release of at least one button of the key fob concurrently with engagement of a second button of the key fob.

20. The method of claim 16, further comprising transmitting the wireless network security protocol initiation signal from a wireless access point.
