“…For performance analysis of the SDS-TWR method the five reference positions (marked with numbers 32, 33, 34, 51, 53) inside the offices were used. Every measurement was carried out on the marked points (cross marker [1][2][3][4][5][6][7][8][9][10][11][12] hall between the offices, so we could evaluate different NLOS (non line-of-sight) multipath signal propagation. Figure 5 shows the worst case measurements in the whole area consolidated by all nodes, so we can see maximum possible error introduced in this environment using the UWB devices and then predict or deal with this occurrences.…”

This study deals with the distance estimation issue in low-power wireless systems being usually used for sensor networking and interconnecting the Internet of Things. There is an effort to locate or track these sensor entities for different needs the radio signal time of flight principle from the theoretical and practical side of application research is evaluated. Since these sensor devices are mainly targeted for low power consumption appliances, there is always need for optimization of any aspects needed for regular sensor operation. For the distance estimation we benefit from IEEE 802.15.4a technology, which offers the precise ranging capabilities. There is no need for additional hardware to be used for the ranging task and all fundamental measurements are acquired within the 15.4a standard compliant hardware in the real environment. The proposed work examines the problems and the solutions for implementation of distance estimation algorithms for WSN devices. The main contribution of the article is seen in this real testbed evaluation of the ranging technology.

“…Even though the performance and the effect of the various communication mode parameters on the performance of the UWB communication have been addressed in multiple studies, none of the works known by the authors provides a comprehensive picture. E.g., in [19] and [20] the authors analytically characterized the effect of the rate, the pulse repetition frequency (PRF) and the preamble length on the packet's on-air time and maximum throughput. The effect of the preamble length and the channel used on the communication distance was analytically studied in [21].…”

The ultrawideband (UWB) radio signals are known for their good time resolution enabling implementation of accurate localization and tracking. The recent appearance of commercial UWB transceivers in masses on the market has boosted the interest towards this technology and facilitated its use not just for research, but also for business. In this paper we focus on the problem of UWB-based wireless indoor localization of machines and humans by means of IEEE 802.15.4-2015 high rate pulse repetition (HRP) UWB technology and specifically the accuracy of such localization. Namely, we report the results of an extensive experimental study revealing the effect of various communication settings on the accuracy of indoor localization for an asymmetric localization protocol. The conducted experiments lasted over 200 hours almost nonstop and involved transmission of more than 30 million ranging packets. In the experiments we have tested over 200 different modes and explored the effect of seven different parameters on the UWB ranging performance. The presented results reveal that the communication settings need to be accounted when determining the time of flight using UWB. Also we show that the accuracy of ranging is strongly affected by the used channel, data rate and pulse repetition frequency. Finally, we note that the increase of the UWB transceiver's temperature due to self-heating has a strong effect on the results of the localization.
