Abstract
Agencies oftentimes desire to monitor personnel in the field during the course of their duties. To provide flexible monitoring capabilities to agencies, a common mobile device such as a mobile phone is converted for use as a radio-based listening system to collect and transmit audio data. A relay is implemented within the system to pass message communications between the mobile device and a server such that the server can facilitate establishment of sessions for monitoring the mobile device.
