Hi all, I have a doubt when I extract the RSSI from messages.

I send 10 message, one per 1/10 second. The mote receive the message
and it extract the RSSI. When tmote receive all messages, it send the
message that it has as payload the 10 RSSI extracted.
I do the average and I observe that the variance of the 10 RSSI is
very low, but when send again 10 message, it is possible that the
variance is again very low, but the average is very different
comparated to the previous average.

The doubt is why the 10 RSSI is very similar in a boost of message and
after certain interval (example 1 second) the 10 RSSI change, but
again the variance is very low??

I thought the RSSI change always even in a boost of message.

P.S.
The two tmotes are always at the same distance.
