The eduroam WiFi network

Česky

Eduroam (Education Roaming) is an international project for easy and secure connection of students and teachers to a wireless network. The University of Ostrava is a member of this project, so a user with a university account can log into the wireless networks of universities and other educational institutions involved in the project. In the Czech Republic, the project is managed by CESNET. Further information can be found at www.eduroam.cz/en
