INTRODUCTION:

Wireless communications is a rapidly growing segment of the communications industry, with the potential to provide high-speed high-quality information exchange between portable devices located anywhere in the world name just a few. Wireless communication involves transmitting signals through air and space using radio waves. Potential applications enabled by this technology include multimedia Internet-enabled cell phones, smart homes and appliances, automated highway systems, video teleconferencing and distance learning, and autonomous sensor networks, to name just a few. Wireless technologies are used to build LANs within building and LANs that bridge buildings. They are also used to provide high-speed access to the Internet or to build metropolitan area networks.

Wireless mobile systems with very high data-rates are emerging that allow mobile users to operate as if they are attached to traditional wired networks. Wireless networks are becoming more pervasive, accelerated by new wireless communications technologies, inexpensive wireless equipment, and broader Internet access availability. These networks are transforming the way people use computers and other personal electronics devices at work, home, and when travelling.There are many wireless communications technologies that can be differentiated by frequency, bandwidth, range, and applications.
