Technology has revolutionized our life. The twentieth century has led to a series of technological innovations that dramatically reshaped the way people communicated at a global level. New means of communication speeded the pace of life and people started finding for more convenient ways to do things easily. This brought in conveyable and anytime accessible laptops with a standard 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 passage to applications. It was in 2002, the data technology industry made a break straight through with the activate of a stock that worked on new standards. Today, we have WiFi signal compel meters advanced on Ieee 802.11 standards.
WiFi provides its users the freedom 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 social place without the hassles of plugging in the wires. WiFi is quicker than the approved modem for accessing data over a large network. Using separate amplifiers, the users can unquestionably convert their location without any disruption in the network access. The location where the users can join together to the network is called a WiFi hotspot. There are separate WiFi software tools available in the market. They are specifically designed for separate 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 in the middle of 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 great technology that provides a total platform for operating Bluetooth strategy, cellular phones, and other scientific equipments. Furthermore, it also provides perfect streaming ability of video, audio and voice channels.
The developments in communication technology have brought in safety threats. There are many safety options available. One of the beloved ways is to use the Wired Equivalency Privacy (Wep) safety standard. Someone else choice is Media passage operate (Mac) address filtering that requires each computer to manually register to have passage to the network. But these options have decreased the total useability of the network and moreover, they can be faked by a hacker with adequate time, knowledge, and network access.
