The complexity of communication channel in mobile communication is analysed in this paper. Some correlative factors of electromagnetic wave propagation loss in wireless communication and their influence for channel parameters are introduced. Some basic characteristics of the propagation models and an overview of popular prediction models are given. In addition, for uncertainty parameters of propagation models, some measure and test methods of local typical value and practical improvements of predetermined models are introduced.
