Design of 3D Spatial Positioning Experiment Based on Wi-Fi

With the maturity of Wi-Fi technology, Wi-Fi positioning is the best choice for indoor spatial positioning. The positioning in two-dimensional space has gradually failed to meet the needs of society. On the basis of previous studies, this experiment explores the three-dimensional spatial location in Wi-Fi environment. Collecting RSS via the Wi-Fi transmission module, this paper presents an algorithm to improve RSS observations by using the average of a number of selected maximum RSS observations. Three-dimensional spatial positioning of the target is realized by using the trilateral measurement method.
