Location of the Subscriber Unit must take into consideration the following guidelines:
• Clear line of site to the AU.
• Height above the ground.
• Distance between sites.
Path of Clearest Propagation
A propagation path is the path that signals traverse between the antennas of any two
bridges. The “line” between two antenna sites is an imaginary straight line, which
may be drawn between the two antennas. Any obstacles in the path of the “line”
degrade the propagation path. The best propagation path is, therefore, a clear line of
sight with good clearance between the “line” and any physical obstacle.
Physical Obstacles
Any physical object in the path between AU and SU can cause signal attenuation.
Common obstructions are buildings and trees. Any buildings or other physical
structure such as trees, mountains or other natural geographic features higher than
the antenna and situated in the path between the two sites can constitute
obstructions. Install outdoor antennas high enough to avoid any obstacles, which may
block the signal.
Minimal Path Loss
Path loss is determined by several factors:
• Distance between sites – Path loss is lower when distances between sites
are shorter.
• Clearance – Path loss is minimized when there exists a clear line of sight. The
number, location, size, and makeup of obstacles determine their contribution
to path loss.
• Antenna height – Path loss is lower when antennas are positioned higher.
Antenna height is the distance from the imaginary line connecting the
antennas at the two sites to “ground” level. “Ground” level in an open area is
the actual ground. In dense urban areas, “ground” level is the average height
of the buildings between the antenna sites.
