_images/nd_power.png — Network Device Power¶

Power Parameters

EIRP: Read only value for all products except PMP 450m, showing the EIRP of the antenna, if the country selected has a regulatory limit this value is shown in brackets underneath.

Power: Read Only. If the country selected has a regulatory limit (or an implied limit to meet the EIRP limit) the value is shown as “Max Power” in brackets underneath. To set the transmit power for the Network Device to a lower value tick the User Limit box and enter the value in the box below it.

SM Receive Target Level: (ePMP and 450 family only) Set the receive power required at the Network Device from each of the Subscribers.

ND Interference: This is the amount of site noise in the selected channel bandwidth, expected at the antenna connector of the ND. This noise is assumed to be a constant power added to the thermal noise of the front end of the radio. The bandwidth displayed depends on the bandwidth selected in the Equipment Settings box (in this example it is 20 MHz). To enter Interference, tick the box and update the default value. If the Network Device has been set up and background power measurements are available, then use these measurements. Available under Component Carriers section for PMP 450v 4x4 ND.

Default SM Interference: Select this option to set the same interference level to every SM attached to the ND. This is the amount of site noise in the selected channel bandwidth, expected at the antenna connector of the SM. This noise is assumed to be a constant power added to the thermal noise of the front end of the radio. The bandwidth displayed depends on the bandwidth selected in the Equipment Settings box (in this example it is 20 MHz). To enter Interference, tick the box and update the default value. Use the Interference on the Subscriber Module Equipment to adjust the level for an individual SM. Available under Component Carriers section for PMP 450v 4x4 ND.

Calculating Tilt Angle¶

To calculate the optimum tilt angle for a Network Device (the mechanical tilt required to give maximum throughput) select the Calc Tilt calc_tilt_button option to display the Calculate Tilt Dialog.

Attach all the required subscriber modules to the Network Device before running this command.

_images/calc_tilt_dialog.png — Calculate Tilt Dialog¶

The dialog shows a number of options:

Min Tilt: Set the minimum tilt angle to consider when running the calculations. The default is the minimum downtilt of the antenna.

Max Tilt: Set the maximum tilt angle to consider when running the calculations. The default is the maximum uptilt of the antenna.

Interval: Set the step interval to define the intermediate tilt angles in the results list. Use a large value if the difference between the Minimum and Maximum is large, reduce the interval for smaller ranges.

Calculate: Start the calculation.

Cancel: Cancel the calculation from running.

Apply Tilt: Apply the selected tilt angle to the network device. The network device will not update unless this command is executed.

When the calculation has finished running, the results are shown below the configuration settings. The angle that offers the maximum throughput has its radio button activated and is automatically selected. If multiple angles offer the same throughput then the middle angle is selected. To use a different angle, select the radio button next to the required row. Select Apply Tilt to update the Network Device to the new tilt angle. The table_download_csv exports the results to a CSV file.
