Not to be confused with the standard free 60GHz LinqPath tool available in EC-Cloud, the Add-on and paid service “LinqPath PRO” will no longer be available after July 31, 2021.
Although the LinqPath PRO version will no longer be available, the free version will continue to be available. The free version will continue to provide estimated signal and throughput numbers for 60GHz Metrolinq and 60GHz Terragraph links.
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 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
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
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
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
What are the LinqPath™ Outputs?
LinqPath provides the following calculations based on the
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.
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.
