Wireless network allow you to be connected to a network without the use of wires. You are free to go anywhere but staying within the range provided by main device.
The advantages of a wireless network is that you don't have to stay in one place to do work. You can go anywhere that has WiFi and use your computer there. Very important if you have to work on a business project.
In my house, wireless internet is king. My son can do his homework in any room, we both have laptops running at the same time and can even take them outside. Which is the best place to work - my back porch!
