Abstract
Control systems and methods are disclosed for automatically identifying mobile communication devices located within a vicinity of a gunshot. The control system may discriminates gunshots from other environmental noise and determine the location of the gunshot from information provided by a set of acoustic sensors. Once the gunshot location is determined, the control system may automatically trigger activation of one or more cell site simulators located near the location of the gunshot to identify mobile communication devices within the vicinity. Further precision in identifying the locations of the mobile communication devices may be obtained by using information from radio frequency (RF) sensors that intercept wireless RF transmissions from the mobile communication devices communicating with the activated cell site simulator. The control system may be used as a tool identifying and tracking perpetrators of gun crime and may also be used to located witnesses who may otherwise not have come forward.
