Aligning The Antenna - BreezeCOM SU-A-2.4 Series Installation Manual

4. ALIGNING THE ANTENNA

Note:
1. Verify that the Power indication (the Yellow LED of the BSSI bar display)
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 towards the general direction of
the base station.
3. The RSSI bar display is located on the bottom panel of the Outdoor unit
(refer to Figure 2-6). 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 point of maximum RSSI reading. 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.
Note:
5. Tighten the bracket screws (or the U-bolts/metal band), firmly securing the
unit or the antenna to the pole.
BreezeACCESS 2.4 Series
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 were properly configured (see Section 3.2). 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 AU.
In some cases (e.g., when the Subscriber Unit is very close to the Base
Station), the antenna might have to be installed at an appropriate angle, in
order to ensure that it is directed towards the Base Station antenna).
