Overview of Wireless LAN/ Wi-Fi / IEEE802.11

As the competition in businesses/corporates is increasing, every minute counts and hence the demand for more productivity, faster response, lower costs is constantly increasing. No doubt, Wired LAN is used most commonly in almost all business / corporate offices, however, if the employer/employee wants to access the even when not present with the traditional desktops, it was not possible. And such kind of demands gave raise to the concept of Wireless LANs.

IEEE 802.11 is the Wireless LAN standard from IEEE (Institute of Electrical and Electronics Engineers) . 802.11 Wireless LAN is commonly referred to as "Wi-Fi" (Wireless Fidelity).

In Wireless LANs, computers, workstations, laptops etc., communicate data with each other using radio waves or infra red light as the transmission medium. Radio transmission (in the 2.4 GHz licencese-free ISM band) is more popular.

Benefits of Wireless LANs:
-> Since, it is not required to use cables or wires to connect to, you can access the required information while moving between floors of your office.
-> Since, it is possible to access information from anywhere (of course, in the vicinity of the coverage area), it is possible for employees to access the key applications and respond quickly to customer queries. Thus, increasing productivity.
-> It is easy to set up since, cables installation is not required
-> Easily add new network elements.
-> Since, wireless networks eliminate or minimize wiring, cost of wiring is eliminated or reduced.
-> Due to the advances in wireless technology, provides robust security protection.

This is just a very brief overview. I will be adding further technical details in another post soon.
