Installing the OSU
This section describes how to find an appropriate installation location for the OSU and how
to install the OSU on the building.
Selecting an installation location for the OSU
It is recommended that you determine the optimum installation location for the OSU before
physically mounting the OSU to the building. There are two methods you can use to
determine the best installation location for the OSU.
Using an RSU to detect signal from a base station
The first method uses a residential subscriber unit (RSU). The RSU can detect where a signal
from the service provider can be received at the installation site.
Most often if you mount the OSU on the side of the building facing the service provider's
base station, the OSU can detect adequate signal in order to provide high-speed Internet
access. However, unless there is an obvious line of sight to the correct base station, the
correct orientation of the OSU is often not apparent. There also may be practical reasons why
you cannot mount the OSU on the side the building that faces the base station.
To use the RSU to determine where you might be able to install the OSU on the building,
point the back of the RSU in the direction in which the OSU is to be oriented. The back of
the RSU is the side without logos.
At each direction you point the RSU, note the number of blinking lights on top of the RSU.
The stronger the signal that the RSU can detect, the more lights blink on and off.
After determining where signal can be detected around the building, you can then choose a
corresponding OSU installation location on the building. As you attach the OSU to the
building, make sure to point it in the same direction that the RSU was pointed when the RSU
detected a signal.
Note: When detecting signal at the site, you must use an RSU that has the same vertical or
horizontal polarization as the OSU to be installed.
Using LinkMonitor application to detect signal from a base
station
The second method of detecting signal from a base station uses the OSU and the
LinkMonitor program that ships on the CD-ROM. The installer connects the OSU to power
and to the installer’s computer. Then, the installer follows the procedure described in the
section “(Optional) Finding the strongest service provider signal” on page 12 in this guide.
Installation overview
To install the OSU:
1 Attach the mounting bracket to the outside of the building.
2 Set the OSU inside the mounting bracket.
3 Tighten the lower mounting bolt to hold the OSU in place.
The following sections describe these steps in greater detail.
