What is the relationship between RSSI and datarate?

Hi,

Recently I am studying the relationship between RSSI and datarate. Intuitively, I think lower the RSSI lower the datarete. Is there any physical evidence for this guess,Are they causal or correlated?

I have done some experiments in this ticket, specifically, I notice my two experiments shows different behaviour, but all the enviroment is identical, so could you please clarify me about the relationship between RSSI and datarate?

RSSI is not related to the datarate at all. RSSI is a measure of the power of the recived signal and will vary with output power, antenna gain and distance only.
