        Tnakyou for your help but in the link you presented only the CAPS (capabilities) is described, there's no information about: AID, TXSEQ, RXSEQ and ERP

          CAPS = Capabilities

          Depending on the capabilities of the APs, the following flags can be included in the output:

          E - Extended Service Set (ESS). Indicates that the station is part of an infrastructure network (in contrast to an IBSS/ad-hoc network).

          I - IBSS/ad-hoc network. Indicates that the station is part of an ad-hoc network (in contrast to an ESS network).

          P - Privacy. Data confidentiality is required for all data frames exchanged within the BSS. This means that this BSS requires the station to use cryptographic means such as WEP, TKIP or AES-CCMP to encrypt/decrypt data frames being exchanged with others.

          S - Short Preamble. Indicates that the network is using short preambles (defined in 802.11b High Rate/DSSS PHY, short pre- amble utilizes a 56 bit sync field in contrast to a 128 bit field used in long preamble mode).

          s - Short slot time. Indicates that the network is using a short slot time.

          –-------------------------------------------------------------------

          AID = Association ID (describes the ID that the AP has given to a certain mac/client)
          IDLE = idletime
          TXSEQ = Transmit Sequence
          RXSEQ = Receive Sequence
          ERP set to 0 means the device is 802.11 compliant. For more info about ERP read up on the 802.11 standard.
          RSSI = Receive Signal Strength Indicator

          RSSI to dBm can be calculated like this for Atheros cards:

          RSSI_Max = 60
          Convert % to RSSI
          Subtract 95 from RSSI to derive dBm
          Notice that this gives a dBm range of –35dBm at 100% and –95dBm at 0%.

          PS. RSSI is different for most vendors. and can not be campared easily (ex. Cisco has 0 -->100 ). Also it is not a very acurate means to measure signal quality, rather it measures strengt only.
