3.4 Aligning the Si CPE's Antenna
The Signal link quality 7-LEDs display is located on the top panel of the unit. The
higher the number of LEDs that are on, the better the quality of the received
signal. Refer to
“Si CPE Top Panel Components” on page 37 for more details on the
functionality of the LEDs.
The link quality can be estimated more accurately using the Link Quality Display
option in the SU Installer Monitor program. Refer to
Section 4.9.1 for more details
on this option.
This section describes how to align the Subscriber Unit antenna using either the
Signal 7-LEDs display or the Start Link Quality Display option of the Monitor
program.
In the following instructions, the term "antenna" means either the selected
integral antenna or a detached antenna. The default active antenna is the internal
antenna number 3 (opposite to the connectors' side). Refer to
Section 4.7.3 for
instructions on changing the active antenna selection.
1
Point the antenna towards the general direction of the Base Station.
2
Verify that the power indication of the unit is on.
3
Verify that the green Status LED illuminates and at least one LED of the
Signal LEDs is on, indicating that the unit is synchronized with the Base
Station. If the SU is not synchronized with the Base Station, ensure that all
parameters are configured properly. If the unit is still not synchronized with
the Base Station, try improving the quality of the link by changing the
direction of the antenna or by placing the antenna at a higher or alternate
location.
4
Try changing the location/direction of the antenna until the maximum link
quality reading is achieved. If you encounter prolonged difficulty in achieving
the expected link quality, try improving the reception quality by placing the
antenna at an alternate location.
To align the antenna:
