Modeling the radio channel has historically been one of the most difficult parts of mobile radio system design. Channel modeling is the basis for the high-level network planning process (antennae heights, frequency assignment, base station subsystem parameter set, network architecture, etc... ). In this contribution, we will compare two of the most important outdoor macro-cell models, COST 231-WI model and ECC-33 model with simulation and measurement. The measurement is taken in urban areas.
