The quality of the radio connection is represented graphically by the Signal quality bar.
The longer the bar is, the better the radio connection. Try to obtain the best possible
radio connection setting.
If you are using the antenna integrated in the SE681 WiMAX:
Memorise the current location and alignment of your SE681 WiMAX, so that you
can restore it if the connection is broken.
If you are unable to check the display of the signal quality on the screen while align-
ing the antenna:
Activate the Audible feedback option to obtain information about the signal quality
by means of beeps. The closer together the sequence of beeps, the better the con-
nection quality.
Turn or move the SE681 WiMAX or turn the antenna a little at a time and note the
signal quality display. Use this to move the antenna to the position with the best sig-
nal quality.
In addition to the beeps and on-screen bar graph you can also determine the quality of
the connection by how many of the 4 LEDs indicating signal quality are lit up on the
device (RSSI 1–RSSI 4). The more LEDs that light up, the better the connection quality.
If you have turned your SE681 WiMAX or the antenna too far, the connection might
break. You should then return to the alignment that provided a connection and repeat
the procedure for establishing a connection to the WiMAX network. Then make any fine
adjustments step by step.
The connection quality can be detected in two different ways:
CINR (Carrier to Interference and Noise Ratio) measures the signal
quality.
i
RSSI (Received Signal Strength Indication) measures the signal
strength.
The bar indicates either RSSI or CINR values. The used method is pre-
configured by your operator. If RSSI is used the bar is labeled Signal
strength.
When your SE681 WiMAX or outdoor antenna is optimally aligned:
Click End to close the Basic Setup Wizard and apply the settings you have made.
Make sure that in future your SE681 WiMAX or outdoor antenna is always in the set
position.
