Considerations For Changing Antenna Parameters - Radwin 5000 HPMP User Manual

Considerations for Changing Antenna Parameters

maxRegTxPower denote the maximum regulatory Tx Power for the equipment, also having
regard the above three points.
Then, the following relationship must be satisfied:
maxAvailableTxPower min maxRegEIRP
– AntennaGain + CableLoss maxRegTxPower
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.
Notes
The inequality (*) above is always satisfied by the system in accordance with the relevant
regulation.
The precise relationship between the items in inequality (*) is as follows:
• Required Tx Power (per radio) will be adjusted down to the lesser of the value entered
and maxAvailableTxPower
• Tx Power (system) is maxAvailableTxPower + 3 (for 2 radios)
• Max EIRP is maxRegEIRP.
• EIRP is maxAvailableTx Power + Antenna Gain - Cable Loss

• The Max EIRP level will be automatically set according to the
selected band and regulation.
• The EIRP level is the sum of the System Tx Power and the Antenna
Gain minus the Cable Loss.
