Well, the SAS doesn’t care. But to get authorized to transmit and to send heartbeats, the SM needs to communicate SM-AP-cnMaestro. And it needs to use that trick where a CBSD is allowed to transmit very briefly before authorization, and then the AP takes the SM under its wing and gets the grant information from cnMaestro.
Similar mechanism if you set alternate color codes, so SMs can move automatically to an alternate sector.

The AP/SM thing is just a Cambium/CNmaestro thing. CBRS doesn't care who the parent is, it needs to know the bearing/elevation/position.

We imported a sector consisting of just the empty AP, and pre approved onboarding in cnMaestro. It was Authorized and Waiting for Device. Once the new AP was plugged in, it synced and enabled CBRS and the SMs moved over without any manual intervention. Pretty cool.

The SMs should move to the new AP in the SAS admin tool once they register and the grants get re-used. Then once the old AP is empty in cnMaestro SAS Admin tool you deregister the old AP and delete it from the system. No reason to refile all of the subs just to swap out the AP.

The key is ensuring you have a current sheet with all of your sector info and subs info up to date. update the sheet with new AP and your ready to go. Of course to answer your question to make a smoother transition is to place the new ap into part 90 so you obtain all of your subs then update your management tool. I am sure someone here may correct me if im wrong. Thanks Dave On 8/10/20 8:46 AM, Ken Hohhof wrote: Has anyone figured out the best procedure for replacing a Cambium CBRS AP? I’m guessing there is something more elegant and less disruptive than deleting the whole sector while the tech is swapping out the AP and then re importing into cnMaestro from a spreadsheet and hoping everything goes smoothly and customers are only down for a few minutes. I’m talking about replacing an AP that is in service but with issues. Over the years we’ve run into RF issues with the original connectorized 450 APs. I’ve never established whether it’s the AP or the sector antenna, but replacing it solves the modulation and V/H ratio issues. The same procedure would also apply if you are upgrading to a 450i or 450m AP. -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
