3.3.2 Using SAU for Aligning the PRO CPE's
Antenna
The LINK QUALITY bar display on the SAU comprises 9 LEDs:

The WLNK LED indicates that the wireless link is active, and is lit when the
CPE has completed the Network Entry process.

LEDs 1 to 8 (green) and 9 (red) indicate the quality of the received signal. The
higher the number of LEDs illuminating, the better the quality of the received
signal.

If all LEDs, including LED 9 (red) are on, the received signal strength is too
high. This must be avoided, preferably by up-tilting the antenna. As a rule of
thumb, if the CPE is located at a distance of less than 300 meters from the
BTS, it is recommended to up-tilt the antenna by approximately 10° to 15°.
1
Point the antenna toward the general direction of the BTS.
2
Connect the SAU to the ODU.
3
Verify that the PWR (power) indication on the SAU is on.
4
Verify that the WLNK LED indicator is on, indicating that the unit is
synchronized with a BS. If the CPE is not synchronized with a BS, ensure that
all parameters are configured properly. If the unit is still not synchronized with
a BS, improve the quality of the link by changing the direction of the antenna
or by placing the antenna at a higher point or in an alternate location.
LEDs 2-10 (green) and 9 (red) are On RSSI

-21dBm (saturation)
LEDs 2-10 Blinking one after the other During full frequency scan
LEDs 2-10 Blinking as follows: LED 6 lights, after 200ms
LEDs 7 & 5 light, after 200ms LEDs 8 & 4 light, after 200ms
LEDs 9 & 3 light, after 200ms LEDs 10 & 2 light, after 200ms
all the LEDs are extinguished and then the sequence is
repeated.
