I'd like to add that RSSI doesn't seem really correlated with

Lqi seem to be more correlated with distance in the same experiment
I can send you our paper about this if you are interested
This seems strange, unless you were in a very short distance range;
the CC2420's LQI is the soft chip decision coefficients, and so is
directly a result of the SNR (and therefore the RSSI). Your assertion
would only make sense if your links were all in the grey region of
intermediate link quality, in which LQI varies.
