4.1 Find Room Location with Best Signal Strength
The most important factor when installing the SU-I is to find the
location where maximum signal strength is detected. Correct antenna
alignment is essential in obtaining the maximum performance from
the SU-I. A misaligned antenna will decrease the received signal and
can result in a total loss of the connectivity with the base station.
Use the following procedures to test signal strength at various
locations in the room before deciding on the final location to install the
SU-I unit.
Base Station Location
Each SU-I must communicate with a WiMAX base station located in
your area. Identifying the tower or building where the base station
antenna is located can assist in setting up the subscriber. To receive
the best signal, the subscriber requires visual line-of-sight (LOS) and
must be located as close as possible to a window facing the base
station antenna. When the base station antenna is not visible from the
SU-I location, it is still be possible to receive a strong signal reflected
from nearby buildings.

Aiming the SU-I Antenna
The antenna is located inside the black plastic cover on the back of
the SU-I. The subscriber must be positioned with the antenna pointed
straight out the window. The closer the SU-I is positioned to the
window, the more likely it is to receive a strong signal.
