Analysis and Modeling of Wireless Channel Characteristics in Mobile Internet of Things

Channel feature analysis and channel modeling are the foundation for designing mobile IoT wireless communication systems. Firstly, for different application scenarios, channel characterization and channel models of the characteristics of wireless channels in the mobile Internet of Things are analyzed from two aspects: large-scale fading and small-scale fading. Then, three types of channel modeling methods, deterministic modeling, statistical modeling, and machine learning modeling are summarized. Finally, the future challenges of wireless channel modeling in the mobile Internet of Things were explored.
