Eduroam (EN)

eduroam is an international project to promote mobility and roaming in national research and education (NREN) networks. In the Czech Republic, this project is under the umbrella of CESNET. Our school joined the project in August 2019. This was another step towards improving the quality of study and the prestige of the institution.

A registered subscriber can use this wireless network (wherever available) with a single user account. The account is administered by the home (founding) organization.

Using roaming is simple, a properly configured subscriber device connects automatically as soon as the eduroam network is available. Similarly to roaming connections to international networks of mobile operators. Hence the acronym: education roaming.

The service is free for all participants.
