2.4 Fine Tuning of the Bridge Link
The link quality is measured via the Tuning tab. Two quality indicators are
displayed. These are:
•
RSSI (radio signal strength indicator)
•
SQ2 (indication for quality of received signal)
The tuning selection looks like this:
Figure 2.10 Tuning Screen
Two lines are displayed. The top one (green) represents the radio signal strength
indicator (RSSI); the other (red) represents the signal quality (SQ2).
Before the signal quality measurement can be started, the MAC address of the
other bridge unit needs to be entered in the PEER field.
It is also possible to change the update speed of the measurements.
Remember: If this measurement is activated, no normal IP traffic is
possible.
So this mode can only be used during trouble-shooting and
installation.
The status bar at the bottom of the screen shows the current status of the link.
The alignment is done by maximizing the radio signal strength and minimizing
the SQ2 indicator. Slowly turning the antenna left and right, up and down, will
affect the RSSI.
