Interpretting Signal Level

[Christopher]

Hi:

 

I'm writing a program for the n810 that uses the cx3110 in monitor mode. In
the snapshot of the driver I have, sm_drv.c populates the ssi_signal field
in AVS header with the RSSI value. I am hoping someone may be able to point
me to a reference document or a code snippet that would allow me to better
understand two things:

1)      How should that raw RSSI be interpreted for display on a GUI in
terms of broad categories such as 'weak', 'good', and 'strong'? Are there
accepted ranges that can be translated for a user display? In other words,
I'd love to be able to replicate maemo's network selection dialog ("Select
connection") in my GUI.

2)      Is there a function for converting the RSSI from the cx3110 (i.e.,
stlc4560 I guess for the 810) into dBm?

 

Thanks for any information that might help in this regard.

 

Cheers,

 

Christopher
