Distributed Testbed for First Responders
ITL's contribution to DTFR was in the areas of communications, networking, and indoor localization. Specifically, we designed and prototyped a wireless ad hoc network (also known as a mesh network) based on commercial-off-the-shelf (COTS) hardware that provides users with multimedia communication capability. Each handheld communication device is an HP/Compaq iPAQ PDA, a PC tablet, or a PC laptop running on Linux, equipped with an IEEE 802.11b WLAN card, and uploaded with NIST-developed research prototype implementations of a number of protocols and algorithms. These communication devices automatically form a network as the first responders from various jurisdictions converge on the scene of an emergency and are within radio range of each other.
DTFR offers an array of advanced capabilities for first responders and public safety officers. These capabilities include private (one-to-one) / group (teleconferencing) / broadcast voice / data communications, streaming video, sensor information communication, and indoor 3D localization and tracking of responders / officers / civilians / assets. Furthermore, DTFR has interoperability with the Internet, PSTN, and cellular telephone networks.
