A wireless network is defined as the type of telecommunication network whose nodes are interconnected without any wires and the remote transmission of information takes place by means of radio waves at the physical level.
Wireless networking has helped the consumers get rid of bundles of cables and wires so that they can benefit from countless services of the internet without having stuck at one place because of wiring. Wireless networking has made possible quick and reliable file and internet connection sharing. To begin with wireless networking, the first thing needed is a “high speed internet connection at the place where you want to use wireless networking” such as digital subscriber line (DSL) or WI-FI (Software Reviews). Other requirements include wireless networking adapter or a PC card adapter, a modem and a network hub. In case of wide-ranging wireless networking, it is always sensible to use an HP Network Assistant “to validate your wired and wireless network settings” (Hewlett-Packard Development Company). Wireless networks are based on IEEE 802.11 standards which is a set of standards developed by IEEE (Institute of Electrical and Electronics Engineers) to carry out WLAN technology with specifications or protocols like 802.11a, 802.11b, 802.11g, 802.11n having frequency bandwidth of 2.4, 3.6 and 5 GHz.
Wireless Local Area Networks (WLANs) enable a user to connect to a local area network through wireless networking, like a small network in a house or an office. As compared to conventional wired networks, the user just has to put on the computer system and enable the ‘connect to the network’ option to connect to the network. It is that simple. The user does not have to waste time in adjusting wires, cables and plugs. He can take the system he is working on anywhere he wants inside the house or inside the range of access points. Thus, setting up a WLAN saves time and money wasted on setting up cables. Computers inside WLAN can be
