Once you have activated your deployment with the green "Activate" button above, you are ready! In your local Wi-Fi equipment, find the WPA-Enterprise (RADIUS) configuration options. There, you enter any of the RADIUS IP addresses, the matching RADIUS port number, and the RADIUS shared secret, as indicated. The rest of the Wi-Fi configuration is standard eduroam, like SSID=eduroam, WPA2/AES. And then, go ahead and try it out - eduroam users are now able to use your Wi-Fi network.
Remember that the IP/port/secret details are only valid for your own deployment, and are meant to be kept private. Anyone with access to that data can pretend to be your Wi-Fi hotspot!
