Propagating a Strong Radio Signal

In order for wireless communications to function, the signal must have a path
from the transmitter and the receiver and arrive with enough power left in the
signal for the receiver to comprehend what is being sent.There are many factors
that affect how a signal propagates from the transmitter to the receiver. Some of
the factors that affect propagation affect low frequency signals differently from
high frequency signals.This section looks at several factors that impact the propagation
of EM waves, and compares the benefits of low frequencies and higher
frequencies.
