1. A method for detecting a victim wireless device, comprising:
- obtaining a set of wireless bands and a set of time periods, wherein during a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data;
during each of the time periods in the set of time periods;
receiving a signal, if any; and
in the event a signal is received, recording the subset of vacant wireless bands corresponding to that time period; and
after the set of time periods ends, determining whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.

Abstract
A victim wireless device is detected by obtaining a set of wireless bands and a set of time periods. During a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data. During each of the time periods in the set of time periods: a signal, if any, is received; in the event a signal is received, the subset of vacant wireless bands corresponding to that time period is recorded; and after the set of time periods ends, it is determined whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.

15. A system for detecting a victim wireless device, comprising:
-
an interface configured to obtain a set of wireless bands and a set of time periods, wherein during a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data; and a signal processor which is configured during each of the time periods in the set of time periods to; receive a signal, if any; and in the event a signal is received, record the subset of vacant wireless bands corresponding to that time period; and after the set of time periods ends, determine whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.

16. A computer program product for detecting a victim wireless device, the computer program product being embodied in a computer readable storage medium and comprising computer instructions for:
-
obtaining a set of wireless bands and a set of time periods, wherein during a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data; during each of the time periods in the set of time periods; receiving a signal, if any; and in the event a signal is received, recording the subset of vacant wireless bands corresponding to that time period; and after the set of time periods ends, determining whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.
