I am trying to understand the output of the airport command line utility on OSX:

/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I
     agrCtlRSSI: -45
     agrExtRSSI: 0
    agrCtlNoise: -95
    agrExtNoise: 0
          state: running
        op mode: station 
     lastTxRate: 585
        maxRate: 867
lastAssocStatus: 0
    802.11 auth: open
      link auth: wpa2-psk
          BSSID: xx:xx
           SSID: xx
            MCS: 7
        channel: 44,80

While I'd to love how to understand all of the output above, most specifically, I am trying to figure out if there is any way to programmatically get the "Link Speed" as shown in the Network Utility program:

There’s not much documentation available, but these are the basics:

  • agrCtlRSSI - Signal strength. The higher, the better.
  • agrCtlNoise - Noise level. The lower the better.
  • state - operating state (running or not)
  • op mode - station or repeater
  • lastTxRate - last rate of transmission speed
  • maxRate 867 - maximum transmission rate
  • 802.11 auth - authentication type (open, shared, EAP, etc.)
  • link auth: - encryption (WEP, WPA, WPA2, etc)
  • BSSID - Basic Service Set Identifier (usually the MAC address of the WAP)
  • SSID - Service Set Identifier (name of your WiFi network)

The item that you’d be looking for is “lastTxRate”. So, to get that, you can issue the command

$ airport -I | grep lastTxRate

  • "not much"? There is one now: :). – dan May 22 '20 at 08:31
  • Thanks a lot for the great answer. Maybe you also have an idea about agrExtRSSI, agrExtNoise? I have an assumption that they kind of "reserved" for some external/extension wifi card, but I'm not sure. Also lastAssocStatus is not clear – CAMOBAP Oct 20 '22 at 06:34
