This trend is due to the large bandwidth of UWB signals contributing many advantages for positioning, communication, and radar applications: penetration through obstacles, accurate position estimation, high-speed data transmission, and a low-cost, low power transceiver. Commercially available UWB radio modules were evaluated. Such modules have the ability to very precisely measure time of arrival of RF signals, range, or localization. The physical layers specify the received signal strength indicator utilized in the localization technique. We estimated and compared the distance of a walking human with the reference distance in different environments, indoor LOS and hard-NLOS utilizing one of these commercial modules. This report also introduces the identification and mitigation of NLOS channels. The results were highly acceptable for indoor localization because the module attained ranging accuracy in a hard-NLOS environment below one meter.

A promising technology for location-aware sensor networks is an Ultra-wide bandwidth (UWB) transmission due to its robust operation in harsh environments, fine delay resolution, and power efficiency. However, the existence of walls and other obstacles causes a notable challenge in terms of localization, as they can result in positively biased distance estimates. A non-line-of-sight (NLOS) identification and mitigation technique created for UWB technology. A distance mitigation method is proposed using online line-of-sight (LOS) and NLOS identification by Fuzzy logic control decision. The result of the proposed method shows 99 % of the accuracy of the proposed NLOS identification method and less than 20 cm of the measured distance error.
