Technology has revolutionized our life. The twentieth century has led to a series of technological innovations that dramatically reshaped the way habitancy communicated at a global level. New means of communication speeded the pace of life and habitancy started seeing for more favorable ways to do things easily. This brought in transportable and anytime accessible laptops with a accepted wireless networking as known as WiFi.
WiFi, a widely used technology in wireless communication, is a local area network that uses high frequency radio signals to transmit and receive data over distances of a few hundred feet. It provides wireless way to applications. It was in 2002, the facts technology manufactures made a break through with the start of a stock that worked on new standards. Today, we have WiFi signal drive meters advanced on Ieee 802.11 standards.
WiFi provides its users the leisure of connecting to the Internet from any place. They can use any expedient such as a personal computer, video game console, smartphone or digital audio player from their home, office or a communal place without the hassles of plugging in the wires.

The location where the users can associate to the network is called a WiFi hotspot. There are dissimilar WiFi software tools ready in the market. They are specifically designed for dissimilar types of networks and operating systems. Some of them are Aircrack-ng, NetStumbler, OmniPeek, Stumbverter, WiFi Hopper, and Aptools.
Wi-Fi uses radio frequency waves to transmit data between its nodes. These frequency waves are transmitted in the radio bands of 2.4Ghz to 5Ghz spectrum that are similar to television signal transmission. It offers a safe and consistent connectivity. It is proved that 802.11g is a best technology that provides a comprehensive platform for operating Bluetooth strategy, cellular phones, and other scientific equipments. Furthermore, it also provides exquisite streaming capability of video, audio and voice channels.
The developments in communication technology have brought in security threats. There are many security options available. One of the beloved ways is to use the Wired Equivalency Privacy (Wep) security standard. an additional one selection is Media way operate (Mac) address filtering that requires each computer to manually register to have way to the network. But these options have decreased the comprehensive useability of the network and moreover, they can be faked by a hacker with sufficient time, knowledge, and network access.
