Wireless Networking

Many computers are now able to connect to the internet or communicate with other computers in a LAN wirelessly. With wireless communication the data transfer medium is the air through which the radio waves travel.

Wireless networks enable people to connect to the internet or to a LAN wirelessly. This means they can work anywhere they can get a radio signal for their network.
