A wireless device may receive a wireless signal, measure a first energy level in a first frequency band associated with an expected frequency band of the narrow band wireless signal, measure a second energy level in a second frequency band that is offset from and non-overlapping with the first frequency band, and determine whether a difference between the first energy level and the second energy level exceeds a threshold. A wireless receiver of the wireless device may be powered up based at least in part on the difference between the first energy level and the second energy level exceeding the threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting narrow band signals in wide-band interference","description":"Systems and methods are disclosed that may detect a likely presence of a narrow band signal in the presence of wide-band interference without powering up a wireless receiver.
