This model shows a transmitter (at the left) and a receiver
(at the right), where the receiver moves as the model executes.
The channel is a PowerLossChannel with a limited range. When the
receiver is in range, the power depends on the distance to the
transmitter, according to an inverse square law.

This model illustrates the
"wireless" domain, where
communication occurs via
channel models that do not
require physical connectivity.

This model assumes that the
transmitter broadcasts one
watt using an isotropic antenna,
and that anything more than 200
meters from it is out of range.
The receiver has a perfect
efficiency antenna with area
(1cm)^2. The received
power is shown on the plot.
