Abstract

Today, wireless local area network systems using the IEEE 802.11 standard are becoming increasingly widespread to provide radio access for user devices to global networks in various operational scenarios. Along with the access capabilities of the IEEE 802.11az standard at the radio interface level, there is a possibility of implementing high-precision range-finding positioning technology for user devices with decimeter accuracy. This work continues a series of studies dedicated to positioning issues in wireless local area networks using the IEEE 802.11az standard and addresses the problem of investigating the impact of multipath propagation on the accuracy of primary range-finding signal arrival time measurements.
