7.7.1. Adjusting the Direction of the WT
This section describes the procedure for adjusting the antenna direction when a Point-to-Point
System is used.
When adjusting the direction of the WT antenna, use the "Antenna direction adjustment tool"
together with the WT Local Management Tool.
Step 1: Connection between WT (master/slave) and WT Local Management Tool and display the
Receiving Level.
See Subsection 7.7.1.1
-
Method of adjustment for near-distance installation
If circuit design calls for a receive level of -35 dBm or higher, you need to reduce the
transmission level according to the following procedure:
WT (Master) Trans Level : 14dBm → -6dBm (see Subsection 7.7.1.1 (4))
WT (Slave) Trans Level
Step 2: Rough adjustment for the WT (Master)
-
Install the Antenna direction adjustment tool.
-
See Subsection 7.7.1.2
-
Remove the Antenna direction adjustment tool.
Step 3: Rough adjustment for the WT (Slave)
-
Install the Antenna direction adjustment tool.
-
See Subsection 7.7.1.2
-
Remove the Antenna direction adjustment tool.
Step 4: Fine adjustment for the WT (Slave)
-
See Subsection 7.7.1.3
Step 5: Fine adjustment for the WT (Master)
-
See Subsection 7.7.1.3
Step 6: Verification
-
After fine adjustment, use the WT Local Management Tool to final check the receive level.
If the receive level value is within the standard range, the procedure for adjusting the
antenna direction has been completed.
If the receive level value is lower than a standard value, you need to perform Steps 4 and
5 again.
Step 7: Exit the WT Local Management Tool, and remove the cable from the WT adapter.
: 14dBm → -6dBm (see Subsection 7.7.1.1 (4))
