RSSI - Received Signal Strength Indication

Hi,
What is the unit for RSSI? is it dbm? if not, how to convert it to dbm?
Thx,
Al

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
