Aligning the Antenna of the
SU-A/E Subscriber Unit
1. Verify that the outdoor unit’s Power indication is on.
2. Align the antenna (integrated into the front side of the SU-RA outdoor
unit or separate if the unit is an SU-RE) to point in the general
direction of the base station.
3. The RSSI bar display is located on the bottom panel of the outdoor
unit. The eight green RSSI LEDs are used for reading the Received
Signal Strength Indication. The higher the number of green LEDs
that are on, the higher the level of the received signal. Rotate the
antenna left and/or right until you reach the maximum RSSI reading
(as many green bars lit as possible). Make sure that at all times the
front of the antenna faces the general direction of the base station.
4. For proper operation, at least one green LED should be on. If you
cannot reach a point where at least one green LED is on, try to
improve the reception quality by placing the antenna at a higher
point or in a different location.
5. Firmly secure the unit (SU-RA) or the antenna to the pole.
NOTE:
Antenna alignment using the RSSI bar display is possible only after the Access Unit you
wish to associate with is operational and the basic parameters in the Subscriber Unit
were properly configured. Otherwise, the unit will not be able to synchronize and
associate with the Access Unit. As the RSSI measurement is performed on received
frames, its results are meaningless as long as the unit is not associated with an Access
Unit.
NOTE:
As the RSSI bar indicator is not accurate, it is recommended to use the Continuous Link
Quality Display test for more precise alignment of the antenna.
NOTE:
In some cases (e.g., when the Subscriber Unit is very close to the Base Station), the
antenna may have to be installed at an appropriate angle, in order to ensure that it is
directed towards the base station antenna.
