The path between two antennas is referred to as the Line Fresnel Zone
of Sight. There are three main categories of Line of Sight, the
first being full Line of Sight (LOS) where no obstacles reside
between the two antennas, the next is called Near Line of
Sight (nLOS) which includes partial obstructions such as
tree tops between the two antennas and lastly Non Line of Near Line of Sight (nLOS) Line of Sight

signals get diffracted or bent from solid objects near their
path. The radio waves reflecting off the objects may arrive out
of phase with the signals that traveled directly to the receiving
antenna thus reducing the power of the received signal.
