[Tinyos-help] LQI to packet loss rate mapping

  Does anyone know of a function to map lqi value as given 
my CC2420 radio to the actual packet loss rate for the link. 
The adjustLQI() function in MultihopLQI maps LQI value to a 
link cost function, but I was wondering if anyone knows of a 
function that gives the corresponding packet loss rate for 
the link under very low traffic (as LQI cannot account for 
losses due to collision)
