Establishing a radio connection with a WiMAX network
Precisely aligning the antenna
Once you have established a wireless connection to a WiMAX network, align your
SE680 WiMAX modem precisely using the Basic Setup Wizard.
Take extra care to align the SE680 WiMAX modem precisely. The better
i
the connection quality, the faster your Internet connection will be in the
future.
To obtain precise alignment of the SE680 WiMAX modem, turn it a little at a time.
When a connection to a WiMAX network has been established, click on Next to
make fine adjustments to the antenna.
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 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 SE680 WiMAX modem a little at a time and note the signal quality
display. Use this to move the antenna to the position with the best signal quality.
If you have turned your SE680 WiMAX modem too far, the connection might break. You
should then return to the alignment that provided a connection and repeat the proce-
dure for establishing a connection to the WiMAX network. Then make any fine adjust-
ments 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 SE680 WiMAX modem is optimally aligned:
Click End to close the Basic Setup Wizard and apply the settings you have made.
Make sure that in future your SE680 WiMAX modem is always in the set position.
