I am planning to implement wireless network in a public place (such as Hotel) and need some help.
My requirements are as follows
Authenticate guest users before granting access to network.
A page to be displayed in client machine, prompting for the credentials as they try to connect to an SSID.
Client should provide a unique identification such as Cellphone number or Passport number, to get One-time password.
Then client should be provided with one time password for limited period of time.
Clients should not be prompted for credentials even they roam between APs.
I would like to know different hardware platforms required to accomplish all the above criteria. It would be great if anyone can provide an example configuration as well.
