Feature Description

Known Issues

The following issues are known to exist in the current release. Where possible, a workaround appears in the Description column.




Base nodes cannot accept remote node connections when a grant exists only on Carrier1.

Workaround: Set the preferred frequency from Spectrum Management, and then reacquire spectrum.


Remote nodes cannot connect to the base node if the spectrum provided by the SAS for the remote node is different from the base node spectrum.

Workaround: Using Spectrum Management, update base node spectrum to match what is available at the remote node.


After an administrator attempts to reacquire spectrum, the CBRS Summary card displays old information.

Workaround: The card updates when the spectrum reacquisition is completed in about 30 seconds.


When a remote node disconnects from one base node and connects to another base node on different frequencies, a new grant can take up to 20 minutes.

Workaround: Select Reacquire Spectrum to request a new grant immediately.

Fixed Issues

The following issues have been fixed in this release.




TCS did not generate an alert when the SAS suspended a grant.


TCS did not respond to SAS response code 106 (RESEND) correctly.


TCS displayed the incorrect reason description in the CBRS status card when spectrum inquiry results were not available.


CBRS Grant summary chart was not updating properly after the admin reacquired spectrum.


When grants become partially suspended, base nodes stopped using the remaining valid grants.
