I got a response on my ticket with Cambium that Federated had a problem:
“Federated Wireless has reported an issue with their SAS connectivity around 13:15 ETD. Federated Wireless has resolved the connectivity issue and is currently investigating the cause of the outage.” Somehow I thought that in the event cnMaestro lost communication with the SAS, it wouldn’t terminate the grants. Yes, the 5 minute heartbeat timeout is a pain. Especially since the SAS only protects incumbents, there is no protection of GAA vs GAA. So until the PAL auction, in areas with no incumbents (we have no coastal radar in Illinois) the SAS basically just approves all grants. It is an extremely complicated system that currently isn’t doing much other than giving us some additional clean spectrum. Which ain’t nuthin’. The heartbeat thing seems aimed at letting PAL owners (read: mobile carriers) kick us off our channels. And I’m not really clear on how that happens. We request a 20 MHz channel at 3560 but now a bunch of PAL sites start operating and we can’t have that frequency or that channel width any more, do we get a new grant that automatically gets pushed out to the radios, or do our grants just get terminated and we need to take manual action to get the customers back online. I guess that’s a battle to fight another day.

Didn’t I say this would happen? And I was a shored by the vendors, the SAS providers, and everyone else that this wouldn’t happen. Here we are not even really into full production and a provider is down and people have customers down because the grounds don’t last more than five minutes. These grants need to at least last 24 hours if not longer, for this type of situation.
