Wireless LANs have many applications in the real world. They are frequently used to enhance a wired network, not to completely replace them. The following describes some of the applications that are made possible through the power and flexibility of wireless LAN technology.
Doctors and nurses equipped with laptops or PDAs have faster access to patient data. Furthermore, in an emergency situation they can communicate with other departments within the hospital by using WLAN in order to provide quick diagnostics. This is an area where WLAN is allready relatively widely used. As in a majority of cases, WLAN is used to enhance an allready existing wired network.
In business, people can work productively with customers or suppliers in meeting rooms - there is no need to leave the room to check if important emails have arrived or print big files. Instead you can send them from one laptop to another. Senior executives in meetings can make quicker decisions because they have access to real-time information.
Network managers in older buildings, such as schools, hospitals, and warehouses, find WLANs to be a most cost-effective infrastructure solution. When building a new network or expanding the old in-house network, few if any cables need be drawn thru the walls and ceilings.
Network managers in dynamic environments minimize the cost of moves, network extensions, and other changes by eliminating the cost of cabling and installation. The mobile nature of WLAN allows the building and testing of a new network before moving to mission-critical surroundings.
