Wireless network supports a number of useful applications for users or provide high reliability due to the decline of the error caused by the cable. Moreover, the wireless networks provide multiple applications which keep the cost is a realistic and appropriate because of the increase in yield and reduce the time of the interruption of the fault compared with the wired network. Most wireless networks have the work technology to license of a free which makes wireless network a simple in deployment and effective.

Basic configurations:

Wireless network in most cases is expanding wired network only exist, in this case the user can complete the work in a certain place in lieu of the optimal location is less ideal. For example the user can empty the truck by the use of a wireless hand-held to a survey of the material onto the truck. It is more effective than writing articles and then introduced into the personal computer in a place within the service area away from the basin and download.

Other cases include the allocation of the wireless networks that are fully abolish the need to wire. For example, the scene of the response of emergency team to the crash of a plan, the Panel can quickly establish a temporary wireless network in the area of the crash. All the devices are connected directly with each other, the members of the Working access to the central important data related to the crash.

Applications of wireless networks is also part of a general or special scenarios, as the owner of the house or the company can buy and install a network for personal use and for the implementation of specific applications. Usually the applications are make to become available only to employees or the occupants of the house. It can't make access to the applications possible for common public use. In fact, the companies use the guards to ensure the safety of contact with people (licensed) to the network and access to services.

On the other hand the applications submit an open access to anyone. For example, the traveler can use the public wireless LAN at the airport to access the Internet during the waiting plane. The hot spots and public cafes has become widely available at airports and other areas such as hotels, meeting centers, coffee shops and places where there are people who have computers.
