upgrade. DO NOT CUT THE POWER DURING THIS
PERIOD. The upgrade will take up to 2 min.
RSSI indication mode
LED indication mode:
Measure with CPE signal LED on the back of the unit
The signal strength led can be set into 3 different ways and is set in the “Maintenance” tab. Off, Pulse and
Continues can be set where the Pulse method is default.
The Pulse method is described in section
1.6 General Wireless Installation
When continues method is set the led will twinkle with increased rate as the signal strength increase.
Maximum twinkle will appear at 35 dB signal level and then switch to continues light.
Tools tab
On the tools tab you can find a spectrum analyzer tool. This tools presents a graphical
view of what radio energy the SU can hear. When starting a sweep the SU will disconnect
from the Basestation during aprox 20s and will automatically reconnect when the seep is
finished.
The graph presents two different bars a blue and a red.
Blue:
Regular OFDM modulated datapackets, normally this is packets received
from other SUs and/or basestations.
Red:
Radio energy pulses, the red bar indicates the strength of other radio
energy that the SU can hear. A high value on this bar indicates that there is
a interfering source near the SU.
Troubleshooting
If you cannot connect to the AP (or Base Station)
If the subscriber unit cannot associate with the base station, it could be caused by one of the following
issues:
-
The SU position is not optimal (indicated by low signal strength)
