Abstract
A system and method for determining if a first and second device are co-located includes first and second sensors for receiving a sample signal. Each sensor is coupled to the first and second devices. The first and second devices each responsively generate a first and second signal representing the sampled signal. Also included is a transmission device located at the first device for transmitting the first signal to the second device and a receiving device located at the second device for receiving the first signal from the first device. Finally, a signal analysis device determines if the first and second devices are co-located.

A method for determining if a first and a second device are co-located, comprising the steps of:
- sampling a sample signal at the first device and responsively generating a first representative signal of the sample signal;
- sampling the sample signal at the second device and responsively generating a second representative signal of the sample signal;
- transmitting the second representative signal to the first device;
- and
- comparing the first representative signal to the second representative signal.
A method for discriminating between data received from co-located and non co-located devices, comprising the steps of:
- receiving at a base station data from a remote device;
- sampling a sample signal at the remote device and responsively generating a first representative signal of the sample signal;
- sampling the sample signal at the base station and responsively generating a second representative signal of the sample signal;
- determining if the base station and the remote device are co-located;
- and
- processing the data received by the base station if the remote device is co-located.
A system for determining if a first device and a second device are co-located comprising:
- a first sensor located at the first device for receiving a sample signal, the first device responsively generating a first signal representing the sample signal;
- a second sensor located at the second device for receiving a sample signal, the second device responsively generating a second signal representing the sample signal;
- a transmission device located at the first device for transmitting the first signal to the second device;
- a receiving device located at the second device for receiving the first signal from the first device;
- and
- a signal analysis device for determining if the first and second devices are co-located.
A system for determining if a first and second device are co-located comprising:
- means for sampling a sample signal at the first device;
- means for responsively generating a first representative signal of the sample signal at the first device;
- means for sampling the sample signal at the second device;
- means for responsively generating a second representative signal of the sample signal at the second device;
- means for transmitting the second representative signal to the first device;
- and
- means for comparing the first representative signal to the second representative signal.
A computer readable medium having embodied thereon a program, the program being executable by a machine to perform method steps for determining if a first and a second device are co-located, the method steps comprising:
- sampling a sample signal at the first device and responsively generating a first representative signal of the sampled signal;
- receiving from the second device a second representative signal of the sample signal;
- and
- comparing the first representative signal to the second representative signal.
