6 Frequently Asked Questions about “UWB outdoor and indoor base stations are used together”
How many UWB base stations are required for 2D positioning?
Therefore, at least two UWB base stations are required for the 2D positioning of indoor objects using the UWB indoor posi-tioning system. To ensure reliability, we use four positioning base stations with unique IDs, and the principle of positioning is shown in Fig. 1.
Can UWB Positioning System be used in practical deployment?
Both the location and number of UWB positioning base stations are optimized from a theoretical point of view, and good results are obtained through simulation and experimental verification. Therefore, the paper provides a new reference for the practical deployment application of UWB positioning system.
Does the layout of UWB base stations affect positioning accuracy?
The simulation results show that the layout of UWB base sta-tions has a greater impact on the positioning accuracy, and the more averaged the distribution of distances from the area to be located to each base station, the higher the positioning accuracy.
How accurate is UWB indoor positioning?
Although the accuracy of UWB indoor positioning has now reached about 10 cm, it still does not meet the needs of industrial development, so the research on UWB indoor precise positioning algorithms is crucial.
What is UWB positioning technology?
Ultra Wideband (UWB) (Oppermann and Iinatti, 2004, Ruming, 2009) position-ing technology has attracted more and more attention due to the advantages of high positioning accuracy. For UWB positioning technology, the cost of base-station deployment network lim-its its wide application.
Is UWB base station layout suitable for underground parking garages?
Another literature (jindong, 2021) summarized the three-stage design method of UWB base station layout scheme suitable for underground parking garages, and provided a scientific base-station layout process for practical scenarios.
