-Airodump-ng is used for packet capturing of raw 802.11 frames and is particularly suitable for collecting WEP [[http://en.wikipedia.org/wiki/Initialization_vector|IVs]] (Initialization Vector) for the intent of using them with [[aircrack-ng]].

It is particularly suitable for collecting WEP [[http://en.wikipedia.org/wiki/Initialization_vector|IVs]] (Initialization Vector) or [[wpa_capture|WPA handshakes]] for the intent of using them with [[aircrack-ng]]. If you have a GPS receiver connected to the computer, airodump-ng is capable of logging the coordinates of the found access points.

Its signification depends on the driver, but as you get closer to the AP or the station, the signal gets higher. It usually is the [[https://en.wikipedia.org/wiki/Received_signal_strength_indication|RSSI]]. If the BSSID PWR is -1, then the driver doesn't support signal level reporting. If PWR is -1 for some access points, it means the access point is out of range, however airodump-ng got at least a frame sent to it. If the PWR is -1 for a limited number of stations then this is for a packet which came from the AP to the client but the client transmissions are out of range for your Wi-Fi adapter. Meaning you are hearing only 1/2 of the communication. If all clients have PWR as -1 then it is likely that the driver doesn't support signal level reporting. A strong signal is around -40. An average one is around -55, and a weak one starts around -70. Wi-Fi adapters lower limit (aka receive sensitivity) is often around -80/-90.|
