There is a growing problem in correctional facilities in which contraband devices may be smuggled into a correctional facility. These devices are not subject to the typical monitoring and control provided by the inmate communication system provided by the correctional facility, and thus pose a significant security risk. The present disclosure provides details of a system and method that leverages the sanctioned mobile devices and the wireless infrastructure of the inmate communication system to scan for and triangulate the location of contraband devices. The mobile and wireless infrastructure devices scan for transmissions indicative of a contraband device and send alerts to each other and to a central monitoring system. The central monitoring system then leverages multiple alerts to determine a location of the contraband device using multiple triangulation techniques. The triangulation may also be performed by the mobile devices themselves.
