Here's an example screenshot:

- CH is the channel on which the AP is setup
- BAT is the remaining battery time
- BSSID is the Access Point MAC address
- PWR is the signal power, which depends on the driver
- Beacons is the total number of beacons
- # IVs: self-explanatory
- MB is the maximum communication speed (the dot mean short preamble).
- ENC is the encryption protocol in use:
OPN = open, WEP? = WEP or WPA (no data), WEP, WPA
- ESSID is the network identifier
The first part is the detected access points (in this case, only 00:13:10:30:24:9C on channel 6 with WEP encryption). It also displays a list of detected wireless clients ("stations"), in this case 00:09:5B:EB:C5:2B and 00:02:2D:C1:5D:1F. By relying on the signal power, one can even physically pinpoint the location of a given station.
