WLAN (Wireless LAN) or Wi-Fi uses a wireless signal, rather than copper wires, to transmit
and receive data in computerized networks. Wireless LAN has become very popular and is
found in many homes, small offices, airports, coffee shops, universities and other public places.
Innovative implementation of WLAN technology has helped people work and communicate more
efficiently. With computers, multimedia devices and other Internet ready devices becoming
readily available, network connections are needed in many places where hard-wired infrastructure
is not available. WLAN provides an easy method for establishing a wireless network, without
cable connections, and rapid setup that is appealing for Internet Service Provider installers or
home owners and small business owners who want to set up their own network.
Wireless users can use the same network based software applications that are used in wired
network applications. Notebook computers utilize wireless adapter and Ethernet adapter cards
that support the same protocol ensuring compatibility. Network based printers, plotters, and
other hardware are also compatible with WLAN using the same operating system hardware
drivers.
6.2 What is a Wireless Network
Wireless Local Area Networks or WLAN’s carry network information using transmitted radio
waves as a communications medium. They are based on IEEE standards, with the most common
being 802.11b/g/n. Wireless networks perform the same function as wired networks, with the
main difference being transmission media. Wireless networks use radio communications
technology and wired networks utilize copper wire. Networks allow computers and other
network enabled devices to share information with each other.
6.3 How does a wireless network work?
A wireless network consists of two or more computers or network enabled devices that are
configured to communicate using radio waves to transfer data or share resources. A network
within a single building or home is usually called a Local Area Network or LAN. The larger
network connecting multiple homes, businesses and universities is called the internet. The
