WI-FI:The modern trends of technology

Wireless networks are very popular nowadays. Wi-Fi® is a system of wirelessly connecting devices that use radio waves, allowing for connection between devices without the expense of cumbersome cables or without needing them to be facing one another. Wi-Fi stands for Wireless Fidelity® and is used to define the wireless technology in the IEEE802.11b standard. It operates in the unlicensed 2.4 GHz radio spectrum, uses direct-sequence spread spectrum (DSSS) for modulation, supports variable data rates up to 11 Mbps, and has a range of about 50 meters. Wireless technology provides us much profit like portability and flexibility, increased productivity, and lower installation costs. Nowadays, communications through mobiles, computers, laptops, wireless networking technologies have extended to a great level. This does a maximum coverage all over the world. Security issues have also been crossed a level in Wi-Fi network because of the unauthorized users and the Wi-Fi hackers. So to implement the feasible Security WEP, WPA has been proposed in this paper to overcome the feasible security problems. These both protocols are generally used to encrypt the current data and information, so that the unauthorized and hackers cannot be able to decrypt the data and hack the Wireless Fidelity (Wi-Fi) networks. Many accessories can be connected with the Wireless Fidelity network with the help the Access Point (AP).
