The most distinguishing characteristic of wireless communication systems is the wireless channel, which has important implications on the design and analysis of wireless transmission technologies. In this chapter, we first provide an overview of wireless channel modeling. Then, the popular models for large-scale channel effects, i.e., path loss and shadowing, are presented. After that, path loss models and shadowing model are respectively applied to the cochannel interference analysis and outage/coverage analysis of wireless communication systems. The fundamental design principle of cellular system is also presented. The small-scale channel effects will be considered in the next chapter.
