Eduroam is a global collaboration where research and educational institutions provide each other's students and staff with access to wireless networks across institutions. Thus, a student at a Danish university may go online at a university abroad without having to register as a user.
Eduroam can be used worldwide and is free. Access is provided at universities, university colleges and other educational institutions. Usage counts millions of logins each month. Eduroam is available in larger urban networks and offers great security.
