Abstract: Purpose. Modern scenarios of high-precision positioning in wireless local area networks require overcoming the limitations associated with multipath propagation of signals and nonlinear delays. To implement the rangefinder positioning method in the absence of synchronization between the reference transceiver nodes, the well-known symmetrical double-sided two-way ranging (SDS-TWR) is used. The aim of the work is to study the application of symmetric two-way bidirectional distance measurement technology in the context of determining the location of a user device in a wireless LAN using nanoLOC technology with an unstable indoor environment. The novelty lies in the development of methodological support for the experimental assessment of the accuracy of positioning devices indoors using nanoLOC technology. The results show that using the nanoLOC system to solve the problem of determining the location of a user device can ensure measurement accuracy within a few decimeters through the use of SDS-TWR method. Practical relevance. The presented study can be used for the applied configuration of indoor location scenarios with the configuration of nanoLOC range measurement acquisition and processing modules, as well as for conducting laboratory classes on applied radio access systems.
Keywords: communications network, location detection systems, WLAN, user device, nanoLOC, ToA (time of arrival), ToF (time of flight), SDS-TWR (symmetric double-sided two way ranging).
