engagehotspots.com provides value-added business models (Facebook promotion and prepaid wi-fi hotspot billing) for public wi-fi hotspots.

You'll need a compatible wireless router running DD-WRT version 24 standard generic (with Chillispot embedded) and a free hotspot administrator account in order to take advantage of one or both of the following available business models:

1. Social Wi-Fi: Customers log into your wi-fi hotspot using their Facebook ID. Each time they log in, a message is posted to their Facebook news-feed stating "[customer name] is enjoy [x] minutes free wi-fi @ [your business name]". Upon login, they are automatically redirected to your Facebook business page and prompted to "like" your business in exchange for news and special offers.
2. Prepaid Wi-Fi: Print off and sell (or give away free) time-limited wi-fi tickets to those customers who perhaps do not have a Facebook ID (with which to login).

Once you've configured Chillispot to connect to engagehotspots.com (for Facebook promotion / prepaid wi-fi hotspot billing), your public wi-fi hotspot will be ready to start accepting customers and you'll be in business!
