Claim Text:
1. An apparatus, comprising: a receiver, coupled with the apparatus, to sense a degradation of radio signals send by a plurality of wireless devices, wherein to sense the degradation of radio signals, the receiver is to consider the radio signals degraded when signal strength of the radio signals is below a threshold level; a motion detector, coupled with the apparatus, to determine a motion characteristic of the apparatus, wherein to determine the motion characteristic of the apparatus, the motion detector is to determine a motion characteristic of the apparatus subsequent to a last known location of the apparatus; a location detector, coupled with the receiver, to determine a current location of the apparatus, wherein to determine the current location of the apparatus the location detector is to determine the current location of the apparatus among one or more dead zones near a last know location of the apparatus, determine a lookup range relative to the last known location of the apparatus based at least in part on the motion characteristic of the computing device and a time lapse since the computing device moved away from the last known location, retrieve a list of predefined dead zones within the lookup range from the last known location, which list comprises characteristics of the dead zones, select a dead zone the apparatus is currently located in or near from the list of predefined dead zones based at least in part on the motion characteristic of the apparatus, and a characteristic of the one or more dead zones.
