RSSI can be measured in any unit of power...
dbm is usually what is used... but can be miliwatts, watts.. if you are
Doc from Back to the future you would use Gigawatts (as he pronounced
"jigawatts" )

The older chipsets used RSSI from 0 to 256. The newer chipsets use 0
to 100. The 0 to 100 flavour is what is commonly used to display
"percent signal strength". The conversion between RSSI and dBm is
non-linear. See the graph in the following paper:

Converting Signal Strength Percentage to dBm Values

I have a question concerning my dell WLAN wireless card. I use a linkysys wireless router and I can see the units of dBm when I look at the networking status. But I can't seem to find a table or formula for changing dBm to RSSI for Dell wireless cards. I've heard that there is no linear equation and that it varies by manufacturer, but WildPackets.com seems to have a system for Cisco products. Does anyone know what I could use for my Dell card? I really hope someone can help me.


Cheers!
