Vic Hayes, who held the chair of IEEE 802.11 for 10 years, and has been called the 'father of Wi-Fi', was involved in designing the initial 802.11b and 802.11a standards within the IEEE. The first wireless products were brought to the market under the name WaveLAN with raw data rates of 1 Mbit/s and 2 Mbit/s. The inventors initially intended to use the technology for cashier systems. In 1991 NCR Corporation/ AT&T (now Nokia Labs and LSI Corporation) invented a precursor to 802.11 in Nieuwegein, The Netherlands. Federal Communications Commission that released the ISM band for unlicensed use. HistoryДЁ02.11 technology has its origins in a 1985 ruling by the U.S. Licensed amateur radio operators may operate 802.11b/g devices under Part 97 of the FCC Rules and Regulations, allowing increased power output but not commercial content or encryption. Frequencies used by channels one through six of 802.11b and 802.11g fall within the 2.4 GHz amateur radio band. In the US, 802.11a and 802.11g devices may be operated without a license, as allowed in Part 15 of the FCC Rules and Regulations. The segment of the radio frequency spectrum used by 802.11 varies between countries. 802.11n can use either the 2.4 GHz or the 5 GHz band 802.11ac uses only the 5 GHz band. Better or worse performance with higher or lower frequencies (channels) may be realized, depending on the environment. 802.11a uses the 5 GHz U-NII band, which, for much of the world, offers at least 23 non-overlapping channels rather than the 2.4 GHz ISM frequency band offering only three non-overlapping channels, where other adjacent channels overlap-see list of WLAN channels. 802.11b and 802.11g control their interference and susceptibility to interference by using direct-sequence spread spectrum (DSSS) and orthogonal frequency-division multiplexing (OFDM) signaling methods, respectively.

Because of this choice of frequency band, 802.11b and g equipment may occasionally suffer interference from microwave ovens, cordless telephones, and Bluetooth devices. Federal Communications Commission Rules and Regulations. ДЁ02.11b and 802.11g use the 2.4 GHz ISM band, operating in the United States under Part 15 of the U.S. Other standards in the family (cвЂ“f, h, j) are service amendments that are used to extend the current scope of the existing standard, which may also include corrections to a previous specification. 802.11-1997 was the first wireless networking standard in the family, but 802.11b was the first widely accepted one, followed by 802.11a, 802.11g, 802.11n, and 802.11ac.

The 802.11 family consists of a series of half-duplex over-the-air modulation techniques that use the same basic protocol. As a result, in the market place, each revision tends to become its own standard. While each amendment is officially revoked when it is incorporated in the latest version of the standard, the corporate world tends to market to the revisions because they concisely denote capabilities of their products. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand. The base version of the standard was released in 1997, and has had subsequent amendments. They are created and maintained by the Institute of Electrical and Electronics Engineers (IEEE) LAN/ MAN Standards Committee ( IEEE 802). IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in the 900 MHz and 2.4, 3.6, 5, and 60 GHz frequency bands. For comparison, this Netgear dual-band router from 2013 uses the AC standard, capable of transmitting 1900 Mbits per second (combined).
