1. A device comprising:

  • a communication component to receive input information including at least a first input corresponding to a first mobile device and a second input corresponding to a second mobile device, the first input including first values, as measured with respect to wireless signals communicated between the first mobile device and a first set of wireless communication devices, the second input including one or more second values, as measured with respect to wireless signals communicated between the second mobile device and a second set of wireless communication devices; and

    a proximity estimator component configured to identify one or more common wireless communication devices, which are included in both the first and second sets of wireless communication devices, the proximity estimator component configured to determine one or more zero-crossing parameter values based on one or more of the first values measured with respect to the one or more common wireless communication devices and one or more of the second values measured with respect to the one or more common wireless communication devices, the proximity estimator component configured to determine a proximity between said first mobile device and said second mobile device, based on a zero-crossing criterion, which is based on a change in a sign of the one or more zero-crossing parameter values.
