Prediction Model
Lee has developed the macro, micro, and pico propagation models. The key advan­
tage of the Lee models is that they can be integrated and work seamlessly together
so that one integrated set of three models can cover all radio planning needs, from
pico- (in-building) to micro- to macrocells. Many field data have been collected and
