不依赖位置坐标的室内Wi-Fi网络覆盖度量方法
Indoor Wi-Fi coverage measurement without spatial coordinates
摘要
Abstract
In R16,3GPP proposed that user devices could utilize the 4G/5G cellular networks to report the received signal strength indicator(RSSI)of Wi-Fi signal based on the existing minimization of drive test(MDT)technology,making it possible to measure the coverage probability of indoor Wi-Fi networks.However,existing measurement methods of network coverage probability based on the MDT require the spatial coordinates provided by the GPS.As GPS has poor indoor localization accuracy,it is not able to be applied to indoor Wi-Fi networks.A measurement method for network coverage probability based on clustering without spatial coordinates was proposed.The proposed method could distin-guish RSSI measurement reported on different locations,with the fact that their statistics were similar at similar locations.The coverage probability was accurately measured by utilizing the clustering results without knowing the spatial coordi-nates.Experimental results show that the coverage probability measured by the proposed method is very close to the prob-ability measured by the known spatial coordinates,and the accuracy is much higher than existing methods.关键词
