What is "Received Signal Quality"? (Orbi LBR20)

[Alex-]

I am in process of educating myself on the terms relevant to understanding signal strength and signal quality. Unfortunately Netgear chose this phrase in the connection status window for the Orbi LBR20: "Received Signal Quality (in dBm)".

I can find information about RSRP, RSRQ, RSSI, SINR etc. but without further explanation, it is not clear how to interpret "Received Signal Quality (in dBm)". What does it refer to and how to evaluate the number?
