A WLAN data transmission occurs over radio signals that are sent out from a wireless router and received by network adapters within individual workstations. This allows for one DSL line to be shared by many and brings the ability to share files and resources from a central point in the network. In a managed network in an office environment, this will be done from a server, and a network administrator will govern all things on there, having special privileges to access it. The fingers that are kept out of the server pie will be beneficial, as the server will be the heart of the entire network. Usually the files and software applications will be stored in that central point to be accessed by the stations on the same network. The ability to file share is something that made the WLAN data transmission capabilities grow. It stemmed from the cabled LAN networks, and works in exactly the same way, except the information is sent through the air via radio waves instead of being sent through cables. This freed up the office workspace of a lot of cabling problems, as well as the expense of having to install new cabling and access
