What is wi-fi?

Wi-Fi is short for "wireless fidelity".  Wi-fi is a wireless networking technology that is commonly used in homes and businesses to provide wireless internet access.  Each computer, laptop, tablet computer, printer, game console, or other device on a wireless network has a wi-fi module installed.  The wi-fi module can be a card that is installed, or wi-fi capability can be integrated into a device.

How Does wi-fi work?

Devices with wi-fi capability communicate with a wireless router using radio signals to transmit data.  The wireless router provides access to the internet and allows devices to communicate with each other on the wi-fi network.  For example, you can stream video from your smartphone to your TV using a Chromecast and your home wi-fi network.  Game consoles can update their firmware and install games using the wi-fi network to access the internet with no need for an ethernet cable to be plugged in.

What is the Range of a wi-fi Network?

Most home wireless routers have a range of about 100 feet.  This means that you should be able to access your wi-fi from all areas of your home and even from outside in your yard if you wish.  In residential areas, you can usually pick up signals from wi-fi routers within a few houses of your location.  You can add encryption to your wi-fi router so that only people who know your password can use your wireless router.

How Do You Install a wi-fi System?

It is easy to install a wi-fi system in your home or business.  You need internet access, typically a DSL line with a modem or DSL router.  Your internet service provider will install this part.  You then simply connect a wireless router using an ethernet cable.  You can buy a high speed wi-fi router for under $100 and install it in a few minutes to provide wireless internet access.
