Abstract

A wireless device (e.g., a mobile telephone) and method of paring wireless devices by positioning a first wireless device within an operable distance from a second wireless device facing each other for a predetermined time period. The wireless devices have detectors and electromagnetic sources. Electromagnetic radiation in a predefined pattern is detected the detector of the first wireless device, wherein the electromagnetic radiation was transmitted from the second electromagnetic radiation source. The detected is processed to establish a wireless communication link (e.g., GSM, CDMA, WCDMA, MBMS, WiFi, WiMax, DVB-H, ISDB-T, Bluetooth, infrared, etc.) between the first wireless device and the second wireless device. Upon establishing the communication link information (e.g., files, multimedia, images, etc.) rendered on one device may be transferred through the communication to the other device.

Claims

1. A method for pairing wireless devices, the method comprising:

positioning a first wireless device having a first detector and a first electromagnetic source on a first surface within an operable distance from a second wireless device having a second detector and a second electromagnetic source on a second surface, wherein the first surface and the second surface are oriented facing each other for a predetermined time period;

detecting electromagnetic radiation in a predefined pattern at the first detector, wherein the electromagnetic radiation was transmitted from the second electromagnetic radiation source;

processing the detected electromagnetic radiation to establish a wireless communication link between the first wireless device and the second wireless device based at least in part on the first wireless device and the second wireless device facing each other for the predetermined time period within the operable distance; and

establishing the wireless communication link between the first wireless device and the second wireless device.

2. The method of claim 1 further including transmitting electromagnetic radiation in the predefined pattern from the first electromagnetic source for receipt by the second detector in response to detecting the electromagnetic radiation transmitted by the second electromagnetic radiation source.

3. The method of claim 2, wherein the step of transmitting electromagnetic radiation in the predefined pattern from the first electromagnetic source to the second detector includes displaying the predefined pattern on a display associated with the first wireless device.

4. The method of claim 3, wherein the predefined pattern is periodically displayed on the display for a duration that is not perceptible to an associated user of the first wireless device and/or the second wireless device.

5. The method of claim 4, wherein the first detector is an optical sensor for detecting the response transmitted from the second wireless device.

7. The method of claim 1, wherein the first electromagnetic source is a light emitting diode that transmits electromagnetic radiation in the predefined pattern.

9. The method of claim 1, wherein the step of processing the detected electromagnetic radiation to establish a wireless communication link between the first wireless device and the second wireless device includes determining whether the detected electromagnetic radiation is valid by comparing the detected electromagnetic radiation to one or more authorized responses stored in a memory of the first wireless device.

10. The method of claim 1 further including detecting the predefined pattern of electromagnetic radiation at the second detector prior to transmitting the predefined pattern to the first wireless device.

11. The method of claim 1, wherein the communication link is a mobile telephony communication link.

12. The method of claim 1, wherein the communication link is a Bluetooth compatible communication link.

13. The method of claim 1 further including automatically transferring a file rendered on the first wireless device to the second wireless device upon establishing the wireless communication link.
