What Is LinqPath?
The IgniteNet LinqPath tool can be used to estimate the maximum distance and signal levels you can expect on a MetroLinq connection given the parameters you've specified. Statistical rain fade calculations are included using the ITU rain model.
How Do I Navigate to LinqPath?
The LinqPath™ tool is available with a free IgniteNet cloud account. You can find LinqPath under the new "Tools" menu in the top navigation menu of the Cloud:
What are the LinqPath™ Inputs?
Next, you will need to set the inputs for the calculations. The definitions of the inputs are as follows:
The MetroLinq model that will be used as the PTP or PTMP master.
The MetroLinq model that will be used as the PTP or PTMP client
The channel that the radio will operate on
ITU Rain Zone
The ITU rain zone in which the link will operate. A map highlighting the various rain regions are provided by the LinqPath tool.
The TX power that will be configured for the MetroLinq 60 GHz radio
60 GHz Rain Reliability
The average percentage of time annually that the expected RSSI and distance with rain will be exceeded for the selected region
Used for the ‘Expected RSSI’ output box – The distance of the link
Used for the Expected RSSI output box – Select No to ignore the effects of rain or select Yes to include rain fade. If yes is selected, the expected RSSI output shows the RSSI levels that should be exceeded the annual percentage of time selected in the ‘60 GHz Rain Reliability’ menu for the input ‘Target Distance’.
What are the LinqPath™ Outputs?
LinqPath provides the following calculations based on the inputs:
The Expected RSSI output box shows the expected RSSI based on the distance provided in the Target Distance input box.
If yes is selected from the ‘With Rain’ drop-down menu, the ‘Expected RSSI’ output shows the RSSI levels for the input ‘Target Distance’ that should be exceeded the percentage of time selected in the ‘60 GHz Rain Reliability’ menu.
Expected Distance Limit
The ‘Expected Distance Limit’ shows the expected maximum distance at which a link with the selected MetroLinq models can achieve 3Gbps, 2 Gbps, and 1 Gbps throughput. The ‘With Rain’ values include the statistical rain fade considerations previously mentioned.
RSSI vs. Distance Graph
LinqPath also produces a graph of the Expected RSSI vs distance. The purple No Rain line indicates the expected RSSI without rain. The blue ‘With Rain’ line indicates the expected RSSI which should be exceeded by the percentage of time selected in the ‘60 GHz Rain Reliability’ drop-down menu. The 1Gbps, 2Gbps, and 3 Gbps lines show the RSSI levels at which each data rate can be achieved.
Can I Save My Calculations?
You can save up to 10 links in your LinqPath link history using the ‘SAVE AS’ button.
