In the modern communication system, wireless systems and communications such as cellular, mobile radio, wireless mouse are becoming popular in their daily life and environment. To achieve an optimized wireless system for an environment, accurate propagation characteristics of the environment should be known. To model for indoor wireless communication is especially difficult because the channel varies according to the environment. The radio wave channel for indoor depends heavily on factors such as structure, layout of rooms and the type of construction materials used. In this paper, their previous propagation and path loss model for indoor wireless is improved by comparing with the previous propagation model.
