“…The former assumes the entity to be tracked endowed with a device that participates actively in the localisation solution, while RF-based device-free localisation systems are tag-less, i.e., without the need of an electronic device mounted on the target. In [9], an indoor positioning system based on Bluetooth 5.1 and angle of arrival measurements is presented. [10] proposes a UWB infrastructure that utilises Time Difference of Arrival (TDoA) for tracking purposes.…”

UltraWide-Band (UWB) low-power devices are becoming an increasingly effective solution for tracking and positioning systems, especially in IoT devices with limited power sources. Background models can be created by analysing the radio frequency or channel impulse response in a static environment. Comparing this background model with runtime measurements it is possible to identify moving objects inducing changes in the impulse responses, and as a consequence, we can compute the distance of the object from the radar devices, usually consisting of one transmitter and one receiver. In particular, using multiple receivers, it becomes possible to elaborate a 2D position of the moving object. This type of tag-less passive tracking system has the advantage of retrieving the trajectory of a moving object without the adoption of any additional electronic device. In this paper, we present an IoT positioning architecture achieving an RMSE of about 30 cm.

“…Wireless localization technology measures ranging or angles and calculates the target's position by radio wave [10], which mainly includes long-term evolution (LTE) [11], ultrawide band (UWB) [12], Wi-Fi [13] and Bluetooth [14]. Compared with other techniques, it relies less on the environment and has been thought of as a promising complement of GNSS.…”

With the rapid development of fully automatic operation (FAO) and location-based services, the evaluation criteria of average localization accuracy can no longer meet our demands, in favor of deterministic localization. However, most localization researches modeled localization performance function and enhanced it by minimizing average localization root mean square error (RMSE). The performance degradation in a small region was not considered. In this paper, we present a survey of deterministic localization and analyze the relationship between accuracy and certainty. In this paper, two common solutions of localization enhancement are presented and their localization certainties are discussed. Furthermore, we carry out related localization enhancement experiments in rail transit line and analyze their improvement on deterministic localization. The experimental results show that the overall localization performance is improved, while the deterministic localization requires the stricter solution to promote.
