how to get exact wireless signal level in dbm or watt?
I was trying to get the signal strength of all the APs in the range.But the problem is I am getting signal level with out any unit like: signal level:203 what does this 203 mean because I need value either in dbm or watt.How to get the exact signal value or how to convert this signal level.Iwconfig help tells that
Received signal strength (RSSI - how strong the received signal is). May be arbitrary units or dBm, iwconfig uses driver meta information to interpret the raw value given by /proc/net/wire- less and display the proper unit or maximum value (using 8 bit arithmetic)
any help will be highly regarded.
