Fading channel modeling for fixed terminal in outdoor environment

Many more customers are now enjoying cellular phone service in not only mobile environments but also non mobile environments. Recently, many customers are using cellular phones outdoors without moving such as on the sidewalks of downtown areas and in parks to communicate; they are moving very slowly or are stopped. In this case, the mobile terminals remain stationary while in use. As a result, the communication characteristics are wildly different from those seen when the terminal is moving. In static usage, the mobile terminal itself doesn't move, but the environment around it changes due to moving obstacles such as people and cars. In order to accurately evaluate the resulting propagation environment, a propagation model (channel model) that can simulate this environment is necessary.
