IE : Information Elements
Refer to Management Frames,
Management frames are quite flexible. Most of the data contained in the frame body uses fixed-length fields called fixed fields and variable-length fields called information elements. Information elements are blobs of data of varying size. Each data blob is tagged with a type number and a size, and it is understood that an information element of a certain type has its data field interpreted in a certain way. New information elements can be defined by newer revisions to the 802.11 specification;
IEEE 802.11i-2004 is standard that specifies security mechanisms for wireless networks.
Wi-Fi Protected Access (WPA) is security protocol and security certification program.
