[Tinyos-help] CC2420 Receiver Sensitivity and RSSI vs. LQI

Hi,
I'm using Telosb motes.
The CC2420 spec states that the Receiver Sensitivity is -90dBm.
But I see that when the RSSI drops under (about) -35dBm there is no
reception.
Moreover, I don't see a correlation between LQI and RSSI - the LQI is always
high (about 100), even when the RSSI drops from 0 to -35.

Any ideas?
