Abstract:
1. A method of using an interloping beacon to cause a target wireless device to respond to an overriding control message provided by the interloping beacon rather than to a control message provided by a live beacon of the target wireless device, the target wireless device operating on a frequency channel of the live beacon in a wireless network that operates according to a standard that employs code division multiplexing to define code channels in the frequency channel, the code channels including a pilot channel for a pilot provided by the live beacon, the target wireless device responding to the pilot of the live beacon by listening for a control message provided by the live beacon on another code channel, the control message occurring in the other code channel at a location which is determined by the standard, and the method comprising the steps performed by a signal generator which generates the interloping beacon of: the overriding pilot and the overriding control message being generated by the signal generator only as long as required to cause the target wireless device to respond to the overriding control message rather than to the control message provided by the live beacon, whereby causing the target wireless device to respond to the overriding control message does not cause another wireless device operating on the frequency channel to respond to the overriding pilot in a manner which is noticeable by a user of the other wireless device.
