Abstract

Reliable positioning capability is a crucial need for first responders in emergency and disaster situations. Lack of a dependable positioning system can result in disruptions in the situational awareness between the local responders in the field and the emergency command and control centers. Indoor localization and navigation poses many challenges for search and rescue teams (i.e. firefighters) such as inability to determine their exact location and communicate with the incident commander outside the building. Although RF navigation and tracking systems have many advantages over other technologies, the harsh indoor RF environment demands new ways of developing and using RF sensor and communication systems. A new approach, proposed recently [1-4], employs passive RFID for geo-location and tracking of a first responder. However, because conventional passive RFID tags have limited communications ranges, a very large number of these tags will be required to fully cover a large multi-storied building without any dead spots. Another technical challenge for conventional RF communications is the transmission of data from the mobile RFID platform (the tag reader) to the outside command and control node, as the buildings walls impose challenges such as attenuation and multipath. In this paper, we introduce a mobile platform architecture that makes optimal use of long-range passive tags, and takes advantage of the frequency diversity of Ultra-wideband (UWB) communication systems for a reliable, robust and yet low-cost infrastructure.
