Preconditions for Use of Links with funkwerk Wx002 Bridges

To set up a wireless link with funkwerk Wx002 Bridges, there has
to be an unobstructed line of sight (LOS) between the antennas on
both sides.
The term "line of sight" does not merely refer to a straight visual
line of sight, but to a kind of tunnel, which must not be hampered
by obstacles.
This "tunnel" is the so-called first Fresnel zone. The Fresnel zone
has the form of an ellipsis rotating around a longitudinal axis. At
least 60 % of the first Fresnel zone have to be unhampered. The
radius (or small semi-axis) depends on the frequency used and the
distance between the antennas.
