This simulator is formed by the junction of Virtual Reality techniques with
propagation models, developed through the studies of radio enlace, describing the
loss that the transmitted signal suffers along the way in the environment. The
Simulator has two modules. The first allows the creation of virtual environment with
the placement, on a ground, buildings, trees, cars, antennas and other primitives that
allow the construction of a customizable three-dimensional environment. The second
module allows the configuration of the parameters related to antenna signal
propagation as power, frequency, gain, etc., and also selects the propagation model
for the simulation execution. Within this second module, there is a submodule
responsible for coverage area planning study composed by antennas, in other words,
this submodule simulates the distance that each antenna in the scenario can reach
and generates its coverage area. To demonstrate the Simulator efficiency was created two virtual environments
for testing. A scenario representing an urban environment where employed a classic
propagation model, Okumura-Hata to small and medium-sized cities, and a wooded
three-dimensional environment using a specific model for propagation simulation of
densely wooded regions, developed at the Federal University of Pará called Lyra-
Castro-UFPA.
