This model is based on extensive experimental data collected by AT&T Wireless Services across the United States in 95 existing macro cells at 1.9GHz. The terrains are classified in three categories. Category A is hilly terrain with moderate-to-heavy tree density and has a high path loss. Category C is mostly flat terrain with light tree density and has a low path loss. Category B is hilly terrain with light tree density or flat terrain with moderate-to-heavy tree density. Category B has an intermediate path loss.
