Wireless Fidelity, otherwise known as WiFi is a high speed internet connection that requires no wires or cables. Wifi has become one of the most popular methods for connection to the internet as it allows users to connect from any system in their home without plugging into a modem as well as the ability to connect from anywhere using their mobile devices.

How Does WiFi Work?
You might be wondering how all the information you are transmitting through your computer, phone or other device is being sent and received without any cable or wire connections. WiFi uses radio waves to transmit data and information to your computer network from the internet. A wireless router is used to convert the radio waves that are being sent and then transmits it to your device that is installed on the network.

The software and hardware that is installed on your computer allows it to interpret the radio waves and gives you the information hat you requested. The same is true in reverse if you use your computer or other device on the network to send information to the internet.
WiFi operates using a high frequency (2.4 Ghz or 5 Ghz) to offer a much faster transfer rate than that of your cell phone.
One router will allow you to connect several devices to your wireless network and all systems on the network can take advantage of the WiFi from anywhere as long as they are in range. Different routers have different ranges that are available and for most home networks the users will be able to transfer data anywhere throughout or around the house.

The wireless router decodes the signals it receives and will send information through the wired connection.
The radio waves used for Wifi are similar to that of warlike talkies, cell phones or other mobile devices. The differences between Wifi and other devices such as cell phones is that the rate in which data is transferred is much faster. The higher frequency signal allows for larger packets of data to be sent and received and of course it happens at a much faster rate that the lower frequency devices offer.
WiFi will allow you to move from one hotspot to another without a break in your connection. Frequency hopping will offer you the fastest transfer rate from several connections in the area. Several devices can be using the network at the same time without any interference of one another and without slowing down the transfer rates.

WiFi Hot Spots
When you have a router installed in your home, your home becomes a “WiFi hotspot” but away from home you will find that many other hotspots exist and will allow you to log on to their network and use their connection to transfer data.
Airports, hotels, libraries and coffee shops are the most popular hotspots that are found throughout the area. These public areas allow their visitors to take advantage of their wireless network so they can check e-mails, surf the web or transfer files.
