HOW DOES WIFI WORK (WIRELESS FIDELITY)

Wireless Internet access allows you to get rid of the cables dangling from the back of your PCs by giving you access to the internet via radio waves. So that you can connect to the internet without using an RJ45.

Here's how it works:

• Wifi uses high frequency radio signals a technology (usually referred to as IEEE 802.11b, 802.11a or IEEE 802.11g) to provide a reliable wireless network connection for laptops which is wifi compliant, the internet connection could originates from a DSL or high-speed land-based Internet connection. Wireless network uses infrared or radio frequency of between 2.4 to 2.4835 gigahertz (which is also the frequency of common microwaves and cordless telephones) to link several mobile computer to its network. Mind you IEEE stands for Institute of electrical and electronics engineers. This institution produce the set of standards and specifications that defines the format and structure of wifi signals.

• A Wifi connection becomes available when router or wireless access point ( Routers are device that is able to broadcast wireless internet connection) transmits wifi signal it receives from a DSL or cable Internet connection. The antenna on the router beam this radio signal over a specific range which is about 300 feet for most home connections. The farther the user is from the signal, the slower the connection speed. With this in place any computer device with wireless adapter can connect wireless-ly to the internet by picking the signal broadcast from the Router. A wireless access point can also transmit wifi network it gets through a wired Local  Area Network or wifi connection from a router.

• Another antenna, which is installed internally in the laptop or personal computer, receives or catches the signal. With some clicks you can connect your laptop to wifi connection. for more information on how to connect your laptop see how to hookup to a free wifi connection.
