Managing hotspots with some great software
WiFi hotspots can exist either in an enterprise environment or a separate commercial location. In both cases it is unwise to provide unrestricted and unlimited access In an enterprise context you do not want inappropriate use of the wifi where a person views web sites that might be offensive to others in close proximity. Additionally, in a commercial location you might want to provide a voucher number to be used in the hotspot to account for a sale or to ensure that only legitimate customers enjoy the service.
