RSSI, strictly speaking, is the received signal strength. (Received Signal Strength Indicator) The signal can be totally unmodulated or modulated in a very complex method with the same RSSI. I am wondering if what you are asking is about the minimum RSSI needed. Generally speaking, the more

I'm not sure exactly your question? I'm also not sure there is a purpose, as much as reporting what occurs. I'm also not sure if you are looking for an answer at the waveform level versus the Link budget level? RSSI is a factor related to Modulation. More specifically with OFDM. Often in
