[Tinyos-help] About Sensitivity and RSSI.

[Urs Hunkeler]

Hi Madhu, Trisul,


RSSI is not the same as the signal to noise ratio. Having a high RSSI 
value can also mean that in addition to the desired signal there is a 
high noise level, which could then actually lead to the packet being 
dropped (too much interference). So if you have a static link and the 
RSSI values that you observe change substantially, then it is likely 
that something interferes with your transmission.

Cheers,
Urs
