3) Connect a ground cable between the Outdoor unit and an appropriate
grounding point.
4) Connect the Outdoor-to-Indoor shielded CAT5 cable to the Outdoor unit and
route it to the selected location of the PoE Outlet. Assemble the enclosed
connector on the cable.
5) Mount the Indoor Outlet and connect:
• Outdoor-to-Indoor cable to the ‘PWR LAN-OUT’ port.
• CAT5 Ethernet cable (from network) to the ‘LAN-IN’ port.
• AC Input to the power (100-240VAC).
6) Align the antenna and secure the unit by fastening the mounting screws.

Select the best location for the outdoor unit using the following guidelines:
• The outdoor unit can be pole or wall mounted.
• The location should allow easy access to the unit for installation.
• When using an external antenna, the unit should be installed as near as
possible to the antenna.
• Make sure clear Line of Sight between the 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 MU and SU may cause signal attenuation.
Common obstructions are buildings, trees and hills located in the path between the
two sites. 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 distance between sites is
shorter.
• Clearance – Path loss is minimized when there is a clear line of sight. The
number, location, and size 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.
Minimizing path loss maximizes link’s signal strength, throughput and availability.
