Classification: CPC H | IPC H

Claim 0:
1. A method of pairing a first device with a second device for wireless communication therebetween comprising:
the first device transmits signals for a selected duration at selected intervals and in a selected radio frequency range;
the second device scans for signals in the selected radio frequency range, the second device being provided with signal strength data related to respective signals detected when scanning;
the second device determines whether the signal strength data for at least one of the detected signals satisfies signal strength criteria whereby the signal strength data is greater than a selected minimum signal strength criterion and is less than a selected maximum signal strength criterion;
the second device determines whether the detected signals are from either the first device or another device; and
the second device sends the first device a pairing command when the detected signals satisfy the signal strength criteria and the second device determines that the detected signals are only from the first device and not from another device, the second device preventing pairing with the first device when the detected signals are determined to also be from another device.
