- As the name suggests, a key feature and benefit of Wi-Fi is the capability it provides to eliminate the physical constraints of wiring to allow for wireless access between two or more devices. It also makes it possible to network one or more computers to each other wirelessly, as well as connect to other electronic devices such as printers, video game consoles, PDAs and even digital cameras. It has also made it possible to connect locations such as the outdoors that have traditionally not been able to connect because of cabling limitations.

A Wireless RouterA wireless router is an essential device for creating a wireless signal and setting up a wireless connection. A broadband connection is also necessary, via either Cable or DSL. A router typically incorporates a modem as well as a Wi-Fi access point to enable connectivity to the Internet and between devices on the local network. An Ethernet or network cable is required to connect the router so as to establish the wireless connection. -
Wireless USB AdapterOnce a wireless signal has been established, computers and electronic devices can use it to connect to other devices or to the Internet. To connect wirelessly, each of these will need either a wireless network adaptor or Wi-Fi compatibility. If a computer doesn't have a built-in wireless adapter, an external network adapter can be plugged into its USB port. Multiple computers can be connected wirelessly to each other to create a network. - Wi-Fi is able to transmit and receive data over a radius of up to 300 hundred feet by means of high frequency radio signals. The specific radio frequency is 2.4 gigahertz to 2.4835 gigahertz, which is the same range as that used by cordless phones. These wireless signals are broadcast via a transmitting antenna that is connected to the router, and are detected then decoded by Wi-Fi compatible or Wi-Fi enabled devices such as a PC or printer. Wi-Fi provides wireless networking connectivity between multiple devices by employing a form of radio technology referred to as IEEE 802.11b or 802.11a.
- Wi-Fi's wireless networking technology has been adapted for a wide range of uses for personal, business and industrial uses. The most common one is wireless high speed Internet and network connectivity, which is critical to mobile computing, Internet gaming, Voice-over IP (VoIP) and other applications that rely on high-speed broadband access.
