This paper summarizes resources for Wireless Channel and Radio Propagation.
The channel effect includes large scale fading (path loss and shadowing) and small scale fading (multipath). Please refer to the communication textbook by Professor Andrea Goldsmith: Wireless Communications, for more details (Chapter 2 and Chapter 3).
