Стандарт IEEE 802.11 является базовым для всех последующих спецификаций (802.11a, 802.11b, 802.11g, 802.11n). IEEE 802.11 is a set of IEEE standards that provides wireless transmission methods. They are commonly named IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and the newer version IEEE 802.11n. The original version of the standard IEEE 802.11 was released in 1997 and clarified in 1999, but is today obsolete. It specified two net bit rates of 1 or 2 megabits per second (Mbit/s), plus forward error correction code. IEEE 802.11 Wi-Fi standards IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wirelessThey are created and maintained by the Institute of Electrical and Electronics Engineers (IEEE) LAN/MAN Standards Committee (IEEE 802). IEEE standards define the physical layer and the Media Access Control (MAC) sublayer of the data link layer of the OSI model. The original 802.11 wireless standard was completed in June, 1997. It was revised in 1999 to create IEEE 802.11a/b and then reaffirmed in 2003 as IEEE 802.11g. IEEE 802.11n is an amendment to the IEEE 802.11 standard and proposes enhancements for Higher for higher throughput using MIMO-OFDM [9]. IEEE 802.11n brings many new features to deliver the performance gains. This paper provides the major differences between various IEEE 802.11 standards, their operation, interoperability and deployment constraints. In this paper, performances of IEEE 802.11a/b/g/n standards are explained. As a result the Wi-Fi, IEEE 802.11 standard is widely used to provide WLAN solutions both for temporary connections in hotspots in cafes, airports, hotels and similar places as well as within office scenarios. Like other IEEE 802 standards, this layer also focuses on the bottom two layers of the OSI model i.e. physical layer and data link layer. The objective of IEEE 802.11 was to define a medium access control (MAC) sublayer A. IEEE802.11a The IEEE802.11a standard was released on September 1999.
