4. ALIGNING THE ANTENNA (A7 MODEL)
When using high gain antennas with a narrow beam width, an alignment procedure is necessary in
order to optimize the quality of the link with the Access Unit.
For a Subscriber Unit with a directional antenna, you can either use the LED indicators on the
front panel of the unit or view the Received Signal Strength Indication (RSSI) using the monitor
program. In most installations, alignment using the LEDs is sufficient. The RSSI reading can be
used when finer alignment is required (see 3.2).
Note:
Antenna alignment of the Subscriber Unit is possible only after the Access Unit you wish to
associate with is operational and the basic parameters were properly configured as
described in Section 3.2.
4.1 Aligning the Antenna Using the LEDs
1.
The H (high), M (medium) and L (low) LEDs on the front panrel of the unit indicate the
quality of the link. The higher the number of illuminated LEDs the better is the quality of the
link.
2.
Rotate the antenna left and/or right until you reach the point of maximal signal quality
reading on the H, M and L LEDs. Make sure that at all times, the front of the antenna faces
the general direction of the Access Unit. In some cases, e.g. when the unit is very close to
the base station you may need to tilt the antenna upward or downward.
3.
For proper operation, at least one (L) LED should be illuminated. If this is not possible,
improve the link quality by placing the antenna at a higher point or in a different location.
4.
After the antenna is optimally aligned, secure the antenna to guarantee that it will remain in
the selected position.
4.2 Aligning the Antenna Using the Site Survey Menu
1.
Start the Monitor program as described in Section 3.1.
