Abstract

Systems and methods which facilitate wireless communications within a controlled environment in a controlled manner are shown. Embodiments operate to recognize wireless communications terminating within a controlled environment facility and control one or more aspects of the communications. Embodiments also operate to detect wireless devices disposed within a controlled environment facility and determine the location of the wireless devices. Embodiments deploy one or more wireless communication nodes in communication with an information processing platform operating in association with the controlled environment facility, such that wireless devices detected by the wireless communication nodes are located by the call processing platform and wireless communications passing through the wireless communication nodes are subject to call processing by the information processing platform.
