Introduction Wireless network is indicated to a telecommunication network whose interconnections between nodes are implemented without the use of wires‚ such a computer network. Nowadays‚ wireless network has become the important thing in telecommunication. This sort of technology has been used for over a century and remains synonymous with radio. In 19th century‚ Guglielmo Marconi invented a radio and made his made his mark in the world of wireless technology. At that moment‚ Marconi was about

Wireless Fidelity ABSTRACT Wi-Fi‚ which stands for “Wireless Fidelity”‚ is a radio technology that networks computers so they connect to each other and to the internet without wires.It refers to wireless LAN products based on the IEEE 802.11b specification.Users can share documents and projects‚as well as an internet connection among various computer stations. A Wi-Fi network operates just like a wired network‚ without restrictions imposed by wires .Not only does it enable users to move around

Introduction Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or the entire communication path. The first wireless transmitters went on the air in the early 20th century using radiotelegraphy (Morse code). Later‚ as modulation made it possible to transmit voices and music via wireless‚ the medium came to be called "radio." With the advent of television‚ fax‚ data communication‚ and the effective use of a larger

“Wireless Network” A wireless network is any type of computer network that uses wireless data connections for connecting network nodes. Wireless networking is a method by which homes‚ telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building‚ or as a connection between various equipment locations.[1] Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation
