Introduction
This document highlights new features and significant updates in cnMaestro Cloud and On-Premises.
Important: Non-CBRS Installations
This patch adds a feature for CBRS (Consumer Broadband Radio Service). It is not otherwise required for cnMaestro 3.0.0 On-Premises installations.
Important: CBRS Installations (added 4/12/2021)
3 GHz PTP 450 Backhaul Users should refrain from doing any CBRS Procedures using cnMaestro’s CBRS Management Tool which requires DEREGISTERING or REGISTERING their PTP CBSDs until a cnMaestro patch release is issued. The Patch is expected no later than 4/15/2021. Any PTP 450 radio that tries to Register with any SAS will be rejected until this new cnMaestro Patch is applied. PTP 450i and PTP 450b CBSDs are NOT affected by this issue and can be Deregistered and/or Registered with any SAS without issue.
If you find yourself already in a state where you have Deregistered a PTP 450 Backhaul CBSD using the cnMaestro Management Tool, it is suggested to use the PTP 450 Master Radio GUI interface to complete any subsequent Registration attempt with your SAS.
Important: Package Upgrade
cnMaestro On-Premises 3.0.2 is a Package release rather than a full OVA image. It must be applied on top of an existing 3.0.0 On-Premises installation.
Important: Web Browser
Restart your browser (or clear the browser cache with a hard reload) in case you still see the 3.0.0 version.
Important: Web Browser
CBRS customers should ignore the banner message “Your free 90-day trial will expire on ". No action is needed if you do not want to continue with cnMaestro X after the trial expires.
CBRS Support for Multiple Grants
Support for CBRS Multiple Grants is available at Services > CBRS > Management Tool. Using the Tool, one can add a Sector and divide Channels into multiple 10 MHz Grants.
For more information on the Multiple Grant feature, refer to the CBRS Consolidated Management Procedures Guide, version 1.6.
