and are used in almost all platforms and around the globe to ensure that all devices on the Internet can communicate successfully. IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4‚ 3.6‚ 5 and 60 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent amendments. These standards provide the basis for wireless

PROJECT 802 LAN STANDARDS The IEEE 802 Standard comprises a family of networking standards that cover the physical layer specifications of technologies from Ethernet to wireless. IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. The better known specifications include 802.3 Ethernet‚ 802.11 Wi-Fi‚ 802.15 Bluetooth/ZigBee‚ and 802.16. All the 802.11 specifications use the Ethernet protocol and Carrier Sense Multiple Access with Collision Avoidance

CHAPTER 1 INTRODUCTION Wi-Fi (ieee-802.11b) and Wi-Max (ieee-802.16e) have captured our attention. As there are no recent developments which transfer data at faster rate as video information transfer taking lot of time. This leads to introduction of Gi-Fi technology. It offers some advantages over Wi-Fi‚ a similar wireless technology. In that it offers faster information rate (Gbps)‚ less power consumption and low cost for short range transmissions.
