To ensure that your Celona Access Points (APs) can access the Citizens Broadband Radio Service (CBRS) spectrum via the Spectrum Access System (SAS) services used by the Federal Communications Commission (FCC) in the United States, you need to activate them by following the instructions in the Activating Celona Access Points via CPI credentials document.

If you need to make changes to an activated and RF transmitting AP, such as changing its location or antenna configuration, you must update the CPI installation parameters on the AP Details page. This update is mandatory and can be done by clicking on the pencil icon next to the Installation parameters. From there, you can edit the latitude and longitude for a CPI Installer in case of a location change, or the antenna model used, azimuth, and downtilt (in degrees) in case of an antenna configuration change for outdoor APs.

If you need to add new APs to a site that already has APs and is currently operational, you must have a Certified Professional Installer (CPI) on your account and add the CPI installation parameters for the new APs. This can be done by clicking on the pencil icon to add the installation parameters.

After making any of these changes, you can schedule your own network downtime, as Celona Orchestrator starts the process of re-acquiring spectrum grants from SAS. The SAS Registration updates require approximately 5-30 minutes of downtime, and Celona Orchestrator provides visible feedback during this process, indicating that the SAS Registration is in progress. Once the process is complete, the Access Point Operational state will be marked as UP, indicating that the maintenance window is complete and your devices can connect back to the Celona network.

The following edit/update scenarios:

For the above scenarios, you may schedule your own network downtime since, after the above edits.

Once the CPI certifies the installation parameters entered on the Access Points Details, the below message will pop up on Celona Orchestrator for an Admin user and conveys that it is mandatory to schedule a SAS Registration for the changed CPI parameters/addition of a new Access Point to a "live" site.

If the CPI installer is not an Admin user, the message on the screen will request an Admin user to schedule the network downtime.

The new banner on all pages on the Celona Orchestrator will direct you to the site where you need to schedule a SAS Registration.

To set up your network downtime, click on the new button Schedule SAS Registration on the Site Details / Access Points Details page.

The scheduler window popup lets you schedule a downtime now which, if selected will start registration with SAS within 5 min of scheduling. You may also schedule downtime for a later time or day depending on operational needs. We recommend scheduling a registration as fast as possible after changing CPI installation parameters to comply with FCC regulations for reporting changes in CPI parameters.

Once you acknowledge the downtime that the network will undergo, the grants will be re-acquired automatically at the scheduled time.

Scheduling a SAS registration is not permitted between 11:30 pm PDT- 3:15 am PDT to avoid SAS interference calculations between different vendor SAS. At this time, some grants may take longer to re-acquire, so Celona avoids this time slot.

Once the above acknowledgment is complete, you can edit the date and time of SAS registration scheduled up to 5 min before the scheduled network downtime.

You can also delete and re-schedule a SAS registration up to 5 min before the scheduled network downtime by clicking on "edit" or "delete" on the banner.

You can track the status of your SAS grants from the Access Points page of the Celona Orchestrator. Once the SAS registration starts Access Points will be Operationally Down on the Access Points Details page. As soon as the grant is received and the radio is “live”, the AP status in the Celona Orchestrator will change to Up.

The AP operational state as reported within the Celona Orchestrator will capture any issues during the SAS process - Registration, Spectrum Acquisition & Spectrum Grant Termination. Customers can also subscribe to AP state change monitoring API from the Celona Orchestrator (contact support@celona.io for access) and be alerted when AP operational state changes due to SAS-related errors.

To check on the status of your site, click the Celona logo (top-left) which will always take you to the main dashboard, showing you the status of all your sites, physical assets, and connected devices.

Select your site that just completed SAS Registration from the dropdown to view the site-specific status of your Celona APs and Edge Clusters.
