HotSpot Managment Software

Dear All
1- I have a separate network for the mobile users who has a laptop, PDA ... ) this network is connected to SENAO ECB 3220 Access points, I am using around 15 Access points to cover the whole campus.

3- Those access points should be connected to hotspot management server which will work as gateway server for those users

4- The system should work like that

- the user will connect to the access point SSID (one SSID for all access points), they will be able to connect without any confirmation or authentication

- When the user lunch the internet explorer automatically should be directed to login page, which will ask him to enter the GSM No.

- I have a database for all users GSM No.

- The system should check if this GSM No is already registered, so would send the random generated ID to this GSM No. through GSM modem.

- This user has limited time to use the internet; once time is over, he should do the same steps again.
