WIFI

WiFi is a globally used wireless networking technology that uses the 802.11 standard. The term WiFi is an abbreviation of ‘wireless fidelity’. The technology used in WiFi was developed in 1997 by the Institute of Electrical and Electronics Engineers (IEEE). This technology was later commercialized by the Wi-Fi Alliance, a trade group.

The basic system of WiFi is very simple. In a WiFi enabled network, computers with WiFi cards connect wirelessly to an access point ...or router. This access point or router is internet enabled the usual way, connected to the internet using a cable or DSL modem. Any PC or laptop with a WiFi card, which is within a radius of 200 feet (60 meters) from the access point can access internet. However a distance of 100 feet (30 meters) is considered ideal for good quality access. An area surrounding an access point, providing wireless access, is called a wireless hotspot. The technology of WiFi was developed to enhance the convenience and increased productivity that portable computing and communication systems ushered in. In today’s scenario, the workforce moves about a lot on business. They typically carry laptops, PDAs and other gadgets and need to access the office network from wherever they are. WiFi is a hassle-free, cost effective and quicker way of deploying a network. It also makes greater flexibility possible. A WiFi enabled work environment helps workers to stay connected for longer and even interact with the co-workers effortlessly. A wireless access point has the risk that anyone can access the information if they get within an accessible distance. Therefore it is important to take security precautions while setting up a WiFi network in your organization. The degree of security depends on the nature of information your organization handles. If it is highly sensitive information, you will need to go for customized security measures.EndFragment
