Performance Evaluation of State-of-the-Art Commercial UWB RFID Systems for Chain of Custody Process
- Lawrence Livermore National Laboratory (LLNL), Livermore, CA (United States)
On demand and real time monitoring and tracking of the stated condition of a nuclear warhead and its components through the dismantlement and disposition process from the point of entry to the point of exit using radio-frequency identification (RFID) tags is a powerful technology for improving chain of custody process. The chain of custody process for on-demand and real-time monitoring may significantly be improved by the use of RFID tags in terms of maintaining the continuity of knowledge for weapons and their components. In addition to tracking of the stated condition of a nuclear warhead and its components through the dismantlement and disposition process from the point of entry to the point of exit may also be aided by use of RFID tags. Most of the commercially available RFID tags use narrowband signaling to communicate with their readers. RFID systems that use narrowband signaling for tag-reader communications face a myriad of technical challenges related to the physical properties and the propagation characteristics of continuous wave RF signals. Although there are no passive UWB RF tags available in the market at this time, several active UWB RFID systems are available in the market that have shown promise for their high performance around metallic objects and accurate positioning capabilities. In this paper, we present the results of LLNL’s performance benchmarking of the state-of-the-art commercial “active” UWB RFID systems for their possible use in arms control applications.
