     When referring to a noise trace, the values are "RSSI" only in the
sense that they are the ambient signal strength received by the radio
at this moment (this is the name of the register sampled, hence the
name RSSISample for the contrib application). This does not imply a
reception of a packet.
     But a file such as meyer-heavy is not precisely the noise floor; it
may contain a higher value than the noise floor because of
interference, such as 802.11.

     What is the gain value that you are using with these noise floors?

Thanks,
