5.2.1 CPE Antenna Alignment Procedure
•
Point the antenna towards the general direction of the Base Station.
• Verify that the power indication of the unit is on.
•
Verify that at least one green LED of the LINK QUALITY bar display is on, indicating
that the unit is synchronized with the base station. If the CPE is not synchronized with
the base station, ensure that all parameters are configured properly. If the CPE is still not
synchronized with the base station, improve the quality of the link by changing the
direction of the antenna or by placing the CPE at a higher or alternate location.
•
Rotate the CPE until the maximum Link Quality reading is achieved. If you encounter
prolonged difficulty in achieving the expected link quality, try to improve the reception
quality by placing the CPE at a higher point or in an alternate location.
Note
Ensure that the front of the antenna is always facing the Base Station. However, in certain conditions,
such as when the line of sight to the Base Station is hampered, better reception may be achieved using
a reflected signal. In this case, the antenna is not necessarily directed toward the Base Station
•
Secure the CPE firmly to the pole.
Note
In some cases, the antenna may need to be tilted to ensure that the level at which the CPE receives
transmissions from the Base Station (and vice versa) is not too high. When all LINK QUALITY LEDS are
on. This indicates that the received signal level is too high (saturation). 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 Base Station, it is recommended to up-tilt the antenna by approximately 10° to 15°

Bar LEDs SNR
WLNK is On CPE is connected with and receives services
from Base station (Network Entry completed)
One bar LED is On (Least
significant) 5dB ≤ SNR < 10dB
Two bar LEDs are On 10dB ≤ SNR < 15dB
Three bar LEDs are On 15dB ≤ SNR < 20dB
Four bar LEDs are On 20dB ≤ SNR < 24dB
Five bar LEDs are On SNR ≥ 24dB and RSSI < -75dBm
