A high-speed radio link, such as the LMDS (local multipoint distribution sy
stem), proves to be quite complex to simulate tinder OPNET modeler radio fr
om the electromagnetic propagation point of view. This paper describes the
introduction of a 3-D radiation diagram in the simulation and integration o
f software computing the electromagnetic propagation, taking note of the mu
ltipath. (C) 2001 John Wiley & Sons, Inc.
