It's hard to explain what i want but I will try to. I will install free wifi zones on many town in a island. but the user will have to watch some ads to connect. The material wil be AP UBIQUITI NANOSTATION M5. In a first time I will need a system that, when the user connect on the hotspot they will have a page that tell them that the 30 min of free connection is brought to you by... the company of the ad.. with a "accept the condition" then they will click OK and will have to watch 10 sec of ads (a must).. then next again to connect... So i will need a system of ads management so the hotspot will connect to "the main server?" to take a random ads to show. This part it's a quick job i think. I find a system like "hotspotsystem" to do it but i'm not sure about it. tell me what you think about it. In a second time, I will need to know more info on the users. So the system of 30 min will become a 10min of connection. if they want more they will have to register and create a personal login. Each time the user connect with his login, the system will have to find out the key words of the website the user visit... so we will be able to target our ads. With our ads management system we will be able to attribute some key words to a ad so the user of the hotspot will have the right ads. On the hotspot they will have 2 connections one open that alloy 10 min free per day with a random ads and one with the login that alloy 30min with a target ad and the possibility of reconnect. You will have to sure that you know how to do this please.
