When local area networks (LANs) first began to emerge as potential business tools in the late 1970s, the IEEE realized that there was a need to define certain LAN standards. To accomplish this task, the IEEE launched what became known as Project 802, named for the year and month it began (1980, February) under which , formed a committee to establish standards for local area network communication. The committee's identifying number reflects the year and month that it was created, "80" - "2".Although the published IEEE 802 standards actually predated the ISO standards, both were in development at roughly the same time, and both shared information that resulted in the creation of two compatible models.Project 802 defined network standards for the physical components of a network (the interface card and the cabling) that are accounted for in the physical and data-link layers of the OSI reference model. A number of separate committees have been formed, each responsible for developing standards in different areas of technology. Of particular interest are the 802.11 committee (with a number of separate working groups) for wireless standards, the 802.1 committee for device interaction and security, and the 802.3 committee for Ethernet networking
IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands.
