“…One important challenge today concerns the non-line-ofsight (NLOS) environment. In previous studies as well as in [28], it is mentioned that localization or even ranging with UWB in NLOS is "still a challenging problem for indoor locations". Complex methods using machine learning for detecting NLOS packet receptions are studied in [22].…”

Ultra Wide Band (UWB) provides ranging capabilities much more precise than other radio communication technologies. This paper presents experimental measurement of ranging precision between two UWB tags when one of the tag is moving fast. The use of a specific electro-pneumatic actuator provides precise ground truth for real distance. This study will allow to improve ranging for human wearable tags as for example sportsmen positionning or interaction between dancers during live performances. We show in particular how the inherent noisy measurement has to be smoothed to obtain more acurate ranging.

“…The two main types of systems are: infrastructure free, that includes systems able to position only with the technology carried by the user like inertial systems or positioning via magnetic field; and infrastructure based, that position using information from sensors and emitters associated to the space. In this last group, we can also distinguish two kinds of systems: dedicated, that deploy sensors or emitters which purpose is positioning, like those systems using beacons [3]- [6]; and not dedicated, that use opportunity signals which are there for other purposes, like WiFi [7], or cellular networks.…”

This paper presents a study of indoor positioning in public zones of the Parc Taulí Hospital in Sabadell. It is a challenging scenario because: 1) it combines wide spaces with middle sized and narrow spaces; 2) it is a shielded zone where no signals are available, and therefore, no WiFi signal can be used for positioning; and 3) it is not possible to deploy beacons for positioning. The goal of this work is to test whether it is possible to get indoor positioning in a real and challenging scenario by using only the magnetic field. The positioning precision requires to locate the part of the hospital where the user is. The proposed solution defines "virtual corridors" to improve positioning in wide areas. To validate the work, magnetic field data have been recorded from the scenario, using different smartphones and by different persons. The obtained magnetic data curves have been compared by using dynamic time warping distance. Results show that it is possible to characterize every path with the magnetic field. The main contributions of the present paper are: 1) defining "virtual corridors" as a way to position using magnetic field in 2D spaces; and 2) showing that even in wide spaces, like the hall of a hospital, it is possible to find magnetic anomalies linked to positions.

Ultra Wide-Band technology has a lot of advantages, such as low power, anti-multipath interference ability, high security, low system complexity, especially high precision in location. It has become a potential technology of indoor wireless location system. Based on location technology of the time difference of arrival (TDOA) , a joint location method based on the Taylor and Chan algorithms is proposed.The simulation has been completed to comparing the algorithms. The design of indoor ultra-wideband wireless location system on FPGA development platform is completed. This paper focuses on the frame structure of the base band signal, the selection of the spreading code, the pulse generation and the synchronization capture. Verilog language is used to design and simulate each part module of the indoor UWB location system.
