A hotspot is a site that offers Internet access over a wireless local area network through the use of a router connected to a link to an Internet service provider. Hotspots typically use Wi-Fi technology.
Hotspots may be found in coffee shops and various other public establishments throughout much of the developed world.

Usually the Wirless network provides pay per usage service. Users have to Pay based on their Internet Usage. Whenever User is connected to wireless network, a unique Identifier(known as Session) is generated for the client. Based on that session ID, the internet usage will be calculated.
