The specification describes techniques for identifying blind spots in a cellular landscape using cellular call traffic analysis. It is based on the recognition that blind spots cause an inordinate number of failed connections. These are calls that either fail to set-up, or are terminated prematurely. Analyzing the call pattern over the area served by a station, and comparing that pattern to a previous pattern, can identify locations of abnormal or unusual changes in call patterns, such as call volume, call duration, etc. These variations will often indicate a blind spot within the network.
