please search the mailing list with keyword "RSSI", I did post some
related question about this.
To be brief, RSSI from the CC2420 chip tell you about the Noise ratio
surrounding, where RSSI value from the received packet tell you about
the quality of the wireless medium.
in your packet you should be able to get thing like rssi() from Message data
msg.rssi();
but please check on the mailing list.

I'm working with tinyOS-2.x under Ubuntu using telosb motes and I would
like to measure the SNR. In the folder apps/tests/cc2420/ there is an
application called RssiToSerial that allows me take samples of the Rssi.
What do you advice me to measure the Signal To Noise ratio when I'm
receiving packets? Is there some application for that goal?
How can I obtain the util signal power or the noise signal power separately?
