Wireless Local Area
1.0. Introduction
Over the last few years, Wireless Local Area Networks (WLANs) have gained strong popularity in a number of vertical markets, including health-care, retail, manufacturing, warehousing, and academic areas. These industries have profited from the productivity gains of using hand-held terminals and notebook computers to transmit real time information to centralized hosts data processing [1].
Wireless communications offer users and organizations many benefits such as portability and flexibility, increase productivity, and lowers cost of installation. Wireless Local Area Network
(WLAN) devices, for instance, allow users to move their mobile devices from place to place within their offices or campuses without the need for wires and also maintaining network connectivity [2]. Less wiring means greater flexibility, increase efficiency, and reduce wiring costs. Handheld devices such as Personal Digital Assistants (PDA) and cell phones allow remote users to synchronize personal databases and provide access to network services such as wireless e-mail, web browsing, and internet services [3].
Wireless Fidelity (Wi-Fi); it is also a way to connect to the internet without wires or cables.
Wi-Fi technology is a set of standards for wireless local area networks based on the specifications known as the Institute of Electrical and Electronic Engineers 802.11 (IEEE
802.11), it was originally developed for use by wireless devices and local networks but it is now used for internet access as well [4].
