The concept of Wlan is simple because you don't require wiring the whole building and you don't require maintenance of the cables also. For wireless networking your personal computers should be installed with wireless network cards which are now a days available in Indian markets in cheaper rates. You will also require wireless access points to allow wireless networking. If you want to allow wireless service in a single floor depending on the distance on or two access point will do. WLAN is simple to setup and maintain but its security is a concern. As there is no physical restrictions to wireless signals any one can enter in to your network without your knowledge. There are special security methods available like WEP, but still they have their limitations. Now a days the concept of wireless is getting importance for its advantages but only time will tell for sure about its existence.
