What is a Wireless Network?
A wireless LAN (local-area network) is a network set up by using radio waves/radio
signal frequencies to communicate and connect with devices like laptops, tablets, computers and to the Internet.
This allows information to be shared wirelessly among wireless devices and its applications. It is also refered to
as a WiFi network, WLAN (wide area network) and 4G data network.
What makes this type of network found just about everywhere these days, in
the home, business, cafe, coffee shops, fast food restaurants and hotels is its easy setup features. The most
popular feature being no cabling required from room to room, between devices. This means that you can connect
up any laptop, tablet, computer and printer anywhere in your home without cables.
So how does a wireless home network work anyway? Here's a quick and simple way to
look at it.
First your Cable/DSL modem receives
encoded information from your ISP Internet Service Provider and sends it to the connected wireless router. Your
wireless router than sends the encoded information to your wireless
computer devices, on your home network, through a radio signal transmission. Each of your wireless computer devices equipped with a wireless adapter will receive the
transmitted information and decode the binary data. This allows you to see the text and images displayed in clear,
understandable and readable format and not in some computer code of ones and zeros.
