Positioning The Su-I Or Su-R Subscriber Unit - Alvarion BreezeACCESS II System Manual

Optimizing the Wireless Link
Positioning the SU-I or SU-R
Subscriber Unit with Omni
Antennas for Optimal
Operation
To identify the best location for the unit you can either use the signal
quality LED indicators on the front panel of the unit or view the
Received Signal Strength Indication (RSSI) on the monitor. In most
installations, alignment using the LEDs is sufficient. The RSSI reading
(see para Configuring the Maximum Data Rate (Subscriber Units)‚
page 2-2) can be used when finer alignment is required.
NOTE:
Finding the optimal location for the Subscriber Unit is possible only after the Access Unit
you wish to associate with is operational and the basic parameters 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.
In SU-I units, Verify that the WIRELESS LINK indicator LED on the
front panel of the unit is lit, indicating that the unit is associated
with the Access Unit. If the WIRELESS LINK LED is not lit, try to
improve reception by changing the location of the unit.
Check the SIGNAL QUALITY L, M and H LEDs. For proper
operation, at least one (L) LED should be on. The higher the number
of LEDs that are on, the better the quality of the link. Change the
location of the unit to identify the optimal position.
NOTE:
If you are using the Continuous Link Quality Display test, search for the location with the
highest RSSI reading.
