As noise becomes a bigger issue, we would be needing micro pops and higher RX signals… anything in the works ? Say a noise floor of -70, for 8x you need 30 snr.. So that’s –40

Anything stronger than -40 dBm can potentially cause damage to the receiver. >From a performance standpoint, you want something less than -45 dBm. Anything >higher can cause some degradation in performance. -55 dBm is a perfectly acceptable target level. In fact, sometimes, you’ll want to set the target slightly higher (like -52 dBm) to overcome higher noise levels.

I know there is ATPC to limit the rcv power at the AP, but what about at the SM? Has anyone heard of a max acceptable rcv signal? Would -55 be too hot? (With FSK we got used to the idea the signal could never be too hot, because what mattered was the zero crossings.)
