4.2.3.1 Point-to-Point
A point-to-point link is based on the use of one Access Point with external
antennas and one adapter (SA-10/40D, WB-10D). The AP and the WB must
be equipped with one or two directional antennas. The necessary antenna
gain depends on the required range and performance.
4.2.3.2 Point-to-Multipoint
Setting up a point-to-multipoint link requires the use of an AP-10D
equipped with omni-directional antennas and a remote WB-10D (or SA-
10/40D) equipped with high-gain directional antennas.
4.2.3.3 Antenna Alignment
Low gain antennas do not require alignment due to their very wide radiation
pattern. High gain antennas have a narrow beamwidth necessitating an
alignment procedure in order to optimize the link.
Check antenna alignment by using the LED indicators on the front panel of
whichever adapter is used in the link (WB-10D or SA-10/40D). These LED
indicators provide indication of reception quality.
⇒⇒ To perform antenna alignment:
1. Assemble antennas according to the assembly instructions included
with the antenna set.
2. Mount the antennas as high as possible.
3. Connect the coaxial cable to the AP at the main site.
4. Connect the coaxial cable to the WB (or SA) at the remote site.
5. Power on the AP and the WB (or SA).
6. Synchronize the units by aligning the antennas manually until the
WLNK indicator LED on the front panel of the wireless Bridge
and/or Station Adapter illuminates.
7. Align antennas at the main and remote sites until maximum signal
quality is obtained. (Check QLT LEDs on the front panel of the
Station Adapter and the wireless Bridge.)
