Address Fields

Acronym(s):

None

Definition(s):

  The MAC header for a data frame contains four distinct address fields, although in some cases not all fields contain relevant addresses. The address fields identify the original source address (SA) and final destination address (DA) in a frame exchange, as well as the receiver address (RA). Depending on the function of the frame, the address fields also identify either the transmitter address (TA) or the BSS identifier (BSSID), which is typically the address of the AP.
