To use Antenna Alignment Tool, follow the steps bellow:
Open “Peer-to-Peer Setup” and select “RF1” or “RF2”. Enter the MAC address of the remote
bridge and click on the Apply button. Then click the “Align Antenna” button and the “Antenna
Alignment Tool” window will popup.
Set the target RSSI (e.g. -70dBm) and click “Start” button.
Wait about 5 seconds, the antenna alignment starts and performs alignment every one second.
Fix the local antenna and adjust the remote antenna elevation and horizontal direction. During the
adjustment, observe “Current RSSI” in local R2 Extender. The value will refresh every 1 second. Fix
the remote antenna when it reaches your expectation. Usually, RSSI between -60 and -70dBm
indicates rather good signal strength.
Adjust the local antenna after fixing the remote one. During the adjustment, observe “Current
RSSI” in the remote R2 Extender. Fix the local antenna when it reaches your expectation.
When the antenna alignment tool starts, the R2 Extender will issue beep sound to indicate current
RSSI. Once the tool is closed the R2 Extender will stop beeping. Frequency of beep indicate the
following RSSI:
Table 3 RSSI-Beep Frequency
RSSI Beep Frequency
>-50 100 /sec
-50~-60 50 /sec
-60~-70 5 /sec
-70~-80 2 / sec
-80~-90 1 /sec
< -90 No beep sound
Link Test
Under Base Station, CPE or Peer-to-Peer (TDMA) mode when Antenna Alignment Tool is not available,
Link Test provides another option to check the signal strength towards the connecting device. Open
“Link Test” in “Wireless” as below, and click “Refresh” to view the current signal strength of wireless
connectivity. The table will be updated every 3 seconds. If the signal is not so good, align the antenna
manually.
