The rise of precise wireless localization for industrial and consumer use is continuing to challenge a significant amount of research. Recently the new ultra-wideband standard IEEE 802.15.4z was released to increase both the robustness and security of the underlying message exchanges. Due to the lack of accessible transceivers, most of the current research on this is of theoretical nature though. This work provides the first experimental evaluation of the ranging performance in realistic environments and also assesses the robustness to different sources of interference. To evaluate the individual aspects, a set of three different experiments are conducted. One experiment with realistic movement and two additional with targeted interference. It could be shown that the cryptographic additions of the new standard can provide sufficient information to improve the reliability of the ranging results under multi-user interference significantly.
工业和消费领域中精确无线定位的兴起持续对大量研究构成挑战。最近，新的超宽带标准IEEE 802.15.4z发布，以提高底层消息交换的鲁棒性和安全性。然而，由于缺乏可使用的收发器，目前对此的大多数研究都具有理论性质。这项工作首次对现实环境中的测距性能进行了实验评估，并评估了对不同干扰源的鲁棒性。为了评估各个方面，进行了一组三个不同的实验。一个是具有实际移动的实验，另外两个是针对干扰的实验。结果表明，新标准的加密附加功能可以提供足够的信息，显著提高多用户干扰下测距结果的可靠性。
