Hi, We implemented hot spot and provide the service in Taiwan, Based on Chilliespot, we provide the <Login with Facebook> service. In this service, we provide user watch shop's timeline message/information(AD) before and after authentication to access internet . It's similar with this project, I think we can achieve this project based on our skills as following:
1. PHP & MYSQL
2. FreeRadius for control the use to connect internet.
3. HTML/CSS/Javascript for web design.
Any need and question, please contact me.
