Captive Wi-Fi or a Captive Portal – it can come under many names but essentially for the end-user it is an Internet Hotspot they can access by doing as little as accepting terms of use or as much as filling in a lengthy form.

 

Generally, a web page or splash screen is displayed before users can access the Internet, apps, or services using a desktop computer or mobile device. Often, captive portals display as login interfaces to guest Wi-Fi connections, like those you find in restaurants, cafes, airport lounges, and hotels.

Gatekeepers as such, most manufacturers are now using them as entry points to, in some way, protect their network connections. Customers simply select the applicable Wi-Fi network (as they would connecting at home), log-in or add their details via a web page or splash screen to gain access to the internet as they go about enjoying their favourite brands and venues and engage in a more powerful experience. You don’t have to go far to see two major experiential brands using Captive Wi-Fi – ANZ Stadium and Etihad Stadium being top of mind.

How do Captive Portals work?

The captive portal’s automatic detection system is based on a simple verification feature of a client device (smartphones, laptops, tablets, and so on). When a guest Wi-Fi connection is activated, the network’s operating system (OS) tries to reach a specific URL and verify that the URL returns a known result.

If there’s no captive portal in place, the OS recognises the URL and allows for full access to the internet. But if the OS detects a different URL, it recognises that there is a captive portal in place and that authentication must take place for the user to gain full access to the Internet.

At that point, the OS automatically opens up a splash page for authentication to take place. The URL may vary depending on the specific model of the mobile device. Regardless, all devices use the strategy described above to find out if they’re behind a captive portal.

To take advantage of a captive portal, a business needs to create a solution that satisfies the following requirements:

  • An easy to use, user interface;
  • Capability of gathering information;
  • Content delivery mechanism;
  • Seamless integration with a back-end data store;
  • Ability to customise level to customer’s needs.

Once a business has these elements in place, you can create and use a captive portal to your advantage.

What are the benefits of Captive Portals?

  • User Data = Customer Insights – Not only can you track the online activity of your customers but you can ask for data before they even access your Captive Wi-Fi.

Take a look at the data captured from a Justin Bieber concert;
