Abstract

A wireless peripheral mode is provided by a host system that communicates to a WiFi infrastructure and, utilizing the same WiFi RF subsystem, also communicates to peripherals. The host system may employ additional RF channels for communicating with high bandwidth peripherals, such as display devices, where high levels of QoS may be managed locally. The host system may be a conventional desktop computer system, a notebook computer system, a multi-media access point, a cell phone, a game machine, a portable game machine, a Personal Digital Assistant (PDA), a smart phone or any other type of device that benefits from accessing both a WiFi infrastructure and local peripherals.

Claims

1. A method comprising:

establishing a Wi-Fi connection between a first device and second device, the Wi-Fi connection enabling wireless communication neither in infrastructure mode nor in standard ad hoc mode; and

transmitting, from the first device to the second device using the Wi-Fi connection, content for display on the second device.

2. The method of claim 1, wherein establishing the Wi-Fi connection between the first device and the second device comprises exchanging a key between the first device and the second device.

3. The method of claim 2, wherein exchanging the key comprises exchanging the key via the established Wi-Fi connection between the first device and the second device.

4. The method of claim 2, wherein exchanging the key comprises exchanging the key via a Wi-Fi infrastructure network.

5. The method of claim 2, wherein exchanging the key between the first device and the second device comprises exchanging a key having an expiration date.

6. The method of claim 2, wherein establishing the Wi-Fi connection between the first device and the second device comprises establishing the Wi-Fi connection between the first device and the second device without receiving a key entered by a user.

7. The method of claim 1 further comprising:

encrypting, by the first device, the content using said exchanged key; and

transmitting, by the first device, the encrypted content to the second device.

8. The method of claim 7, wherein encrypting, by the first device, the content comprises encrypting, by the first device, content having video data.

9. The method of claim 1 further comprising:

generating information associated with the established Wi-Fi connection between the first device and the second device between the first device and the second device; and

storing, at the first device, the generated information associated with the established Wi-Fi connection between the first device and the second device, wherein the generated information is configured to facilitate a subsequent establishing a Wi-Fi connection between the first device and the second device.

10. The method of claim 2, wherein exchanging the key between the first device and the second device comprises receiving, at the first device, the key from the second device.

11. The method of claim 1, wherein establishing the Wi-Fi connection between the first device and the second device comprises establishing wireless communication between a mobile device and a television.

12. The method of claim 1, wherein establishing the Wi-Fi connection between the first device and the second device comprises establishing wireless communication between two mobile devices.

13. The method of claim 12, wherein at least one of the mobile devices is a mobile phone.

14. The method of claim 1, wherein establishing the Wi-Fi connection between the first device and the second device comprises establishing wireless communication using a multiple-input and multiple-output (MIMO) antenna.

15. The method of claim 1, wherein the first device and the second device are each capable of concurrently wirelessly communicating on a second wireless connection.

16. The method of claim 1 further comprising concurrently wirelessly coupling the first device or the second device to a Wi-Fi infrastructure network.

17. The method of claim 1 further comprising:

concurrently wirelessly coupling the first device to a Wi-Fi infrastructure network; and

concurrently wirelessly coupling the second device to the Wi-Fi infrastructure network.

18. The method of claim 1, wherein the first device or the second device is capable of concurrently wirelessly communicating using Bluetooth.

19. The method of claim 1, further comprising concurrently wirelessly coupling the first device or the second device to a cellular network.

20. The method of claim 1, wherein the first device or the second device is capable of concurrently receiving wireless television signals.

21. The method of claim 1, wherein the Wi-Fi connection between the first device and the second device facilitates displaying, on the second device, a display screen of the first device.

22. The method of claim 1, wherein the Wi-Fi connection between the first device and the second device comprises facilitating output of audio content at the second device, the audio content being transmitted from the first device.

23. The method of claim 1, wherein the first device instructs the second device to pause the display of video content.

24. The method of claim 23, wherein the first device transmits the video content in encrypted form to the second device via the Wi-Fi connection between the first device and the second device.

25. The method of claim 1, wherein the second device instructs the first device to pause video content being displayed on the second device.

26. The method of claim 1, wherein the first device transmits to the second device an instruction to retrieve display content from a third device.

27. The method of claim 26, wherein the first device encrypts the instruction using a key exchanged with the second device.

28. The method of claim 1, wherein the first device streams to the second device display content from a third device.

29. The method of claim 28, wherein the third device comprises a server.
