Minimum RSSI to deliver service

Does anyone know what the minimum RSSI for the 450b is to deliver reliable CBRS based service?

It would depend on what constitutes reliable in your environment. The 450 gear works quite reliably at a low RSSI as long as your noise floor is low.

For us, -65 is about the lowest we’ll go in our environment. Much lower than that and customers often see session drops, sometimes lasting for long periods of time. There are a few other operators using CBRS in the area and the noise floor is quite high, generally.

Thanks, our noise floor is practically non-existent.

I think the minimum SnR for PMP450 is around 8dB… you’d never want to install it at those levels. Our minimum RSSI is around -75, and we even try to avoid that if possible.
