[Tinyos-help] Correlation between LQI and RSSI

Dear TinyOS profs,

I have made an experiments with TMote Sky (from moteiv) devices and
collected the RSSI and LQI values given by Tiny OS 2.0 that is installed
on motes. Actually I have expected that LQIs are the correlation values
supported by CC2420 and RSSI is the signal strength in dBm just scaled to
the range defined in the 802.11.4 standard. As I plotted these values and
made some calculations and I have found out that the plots are exactly the
same and the correlation coefficient is 1. Does anybody have a clue why?
