To perform a link test enter a number into the field labeled “
Duration
”. The duration is the number
of seconds the RF link will be tested. Start the link test by clicking the “
Start Test
” button. The test
will now run for the set duration. If the web page is not set to automatically refresh, click the
“
“
Refresh Display
” button to see the results. For a Canopy System link to be considered acceptable
it is necessary for the efficiencies of the link test to be greater than 90% in both the uplink and
downlink direction. It is recommended that when a new link is installed that a link test be executed
to ensure that the efficiencies are within recommended guidelines.

to ensure that the efficiencies are within recommended guidelines.
The key fields are:
• Downlink RATE, bits per second
• Uplink RATE, bits per second
• Downlink Efficiency, percent

Alignment
The Alignment web page contains tools to assist in the alignment of a subscriber module to an
access point module. There are two modes that can be utilized when aligning a module: 1) RSSI
only and 2) normal alignment mode.
access point module. There are two modes that can be utilized when aligning a module: 1) RSSI
only and 2) normal alignment mode.
RSSI Only is a mode where the module will report the signal strength based on the amount of
energy present at a selected frequency. The subscriber module does not have to be registered to
an access point module for information on signal strength to be reported back. This can simplify the
aiming process for long links when the Canopy passive reflector (5.7GHz band only) is being used.

an access point module for information on signal strength to be reported back. This can simplify the
aiming process for long links when the Canopy passive reflector (5.7GHz band only) is being used.
To utilize RSSI only mode:
• Choose the frequency to monitor from the pick list (this would be the same frequency that
the access point module is transmitting on)
• Click the radio button to highlight “
Enable
” on RSSI Only mode
• Click “
Enable Aiming Mode
”
The module will now report back the level of RF energy present at that specific frequency. To

The normal operation of alignment mode will report information as it relates to the RSSI level, Jitter
value, and number of users on the access point module. To utilize normal alignment mode, ensure

button or
configure the auto-refresh option. Also, during normal alignment mode the LEDs on the outside of
the Canopy module will report back information on the performance of the link. There are 6 LEDs
and when in alignment mode the LEDs are turned into a 6-position bar graph. The more LEDs that
are lit, the better the RSSI and Jitter values the module is seeing. The colors of the LEDS have no
particular meaning other than to assist is distinguishing one position from the next.

The minimum values that are needed for an acceptable link are RSSI this above 700, Jitter that is
between 5 and 9, and link efficiencies that are greater than 90% in both the up and down link. If
any one of these criteria are not met the link may still be operational but may have issues time to
