Wi-Fi is increasingly becoming the preferred mode of internet connection all over the world. To access this type of connection, one must have a wireless adapter on their computer. Wi-Fi provides wireless connectivity by emitting frequencies between 2.4GHz to 5GHz based on the amount of data on the network. Areas which are enabled with Wi-Fi connectivity are known as Hot Spots. One can use advanced softwares like Wirelessmon to detect and request connection to Hotspots. To start a Wireless connection, it is important that the wireless router is plugged into the internet connection and that all the required settings are properly installed.
Wireless technology has widely spread lately and you can get connected almost anywhere; at home, at work, in libraries, schools, airports, hotels and even in some restaurants.
Wireless networking is known as Wi-Fi (Wireless Fidelity) or 802.11 networking as it covers the IEEE 802.11 technologies. The major advantage of Wi-Fi is that it is compatible with almost every operating system, game device and advanced printer.
Like mobile phones, a Wi-Fi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent into a radio signal. This same signal will be transmitted, via an antenna, to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection. As the wireless network will work as a two-way traffic, the data received from the Internet will also pass through the router to be coded into a radio signal that will be receipted by the computer's wireless adapter.
