maxODUTxPower denote the maximum Tx Power of the ODU, itself
depending on the air rate used.
Then, the following relationship must be satisfied:
... (*)
These parameters are controlled as follows:
To set Tx power and configure antennas:
1. Click the Configure buttons in turn to configure the antennas on both
sides of the link. Each one offers a dialog like this:
Figure 4-16: Antenna configuration dialog with opened type selection
2. Choose the antenna type and required transmission (Tx) power for the
first site and click OK. Repeat the process for the second site.
The Tx power (per radio) indicates the power of each radio inside the
ODU and is used for Link Budget Calculations. The Tx power (System)
shows the total transmission power of the ODU and is used to calculate
the EIRP according to regulations.
Note
To see the relationship between Tx Power (radio) and TX Power (system),
note that
so that if you double the power in
milliWatts (for two radios) then dBm will increase by
.
