Abstract: The importance of indoor communication scenarios, such as industrial Internet of things, superstores, and stadiums, is becoming increasingly significant in the sixth generation (6G) wireless communication systems. The investigation into indoor line-of-sight (LoS) signal probability is conducive to improving the accuracy of indoor communication performance analysis. In this paper, a LoS probability model is constructed for indoor environments, considering any position and any height of blockages. This model can accurately characterize the LoS probability in different scenarios. Based on the model, this paper derives the signal-to-noise ratio (SNR) distribution and investigates the coverage performance and energy efficiency. The research results are instrumental in instructing the deployment of indoor wireless systems and reducing costs.
