Do you think doing this in this patch makes sense? I think it would not be 
difficult to add this. It would be just the same as with the RSSI.

The problem is that picking the measurement values becomes a lot more difficult 
when I compute the average over all 8 samples. The problem is with the SID 
frames, then suddenly only half of the bursts are sent and recognizing this 
turned out to be difficult. However, the samples are shifted, so the averaging 
always sees all bursts and they are averaged once more in the higher layers. I 
think this has no influence on the final result.
