Antenna Alignment - Alvarion BreezeNET DS.11 User Manual

5. Connect the 10-BaseT connector to the network. The cable connection should
be straight Ethernet when connecting the Indoor unit to a Hub, and a crossed
cable when connecting it directly to a PC Network Interface Card (NIC).
Note:

2.8.1 Antenna Alignment

Usually, low gain antennas do not require alignment due to their very wide
radiation pattern. High gain antennas, including the integral antenna of DS.11 units,
have a narrow beamwidth necessitating an alignment procedure in order to optimize
the link.
Check antenna alignment by using the RSSI bar on the bottom panel of the
RB-DS.11 bottom panel.
To perform antenna alignment:
1. If external antennas are used, assemble antennas according to the assembly
instructions included with the antenna set.
2. Mount the antennas or the DS.11 unit (if the antenna is integrated into the unit)
as high as possible.
3. Connect the antenna to the BU-DS.11, using a suitable RF cable at the main site.
4. Connect the antenna to the RB-DS.11, using a suitable RF cable at the remote site.
5. Power on both units.
6. Synchronize the units by aligning the antennas at the main and remote sites
until maximum signal quality is obtained. Check the signal quality RSSI bar on
the bottom panel of the RB-DS.11 bottom panel. If the received signal quality
level is lower than expected for this antenna/range combination, change
antenna height and verify RF cables connections.
Note:
BreezeNET BU-DS.11/RB-DS.11
The length of the Ethernet cable connecting the Indoor unit to the user's
equipment, together with the length of the Indoor-to-Outdoor cable, should
not exceed 90 meters.
When using external antennas, make sure that the connector is properly sealed
and waterproof.
