WLAN access
BITS operates a campus-wide WLAN radio network. Three networks are offered on the campus of Bielefeld University, which can be used either by members of the university (eduroam) or guests (guest, Bi-free).
Users have the option of connecting devices to the data network via the WLAN and using the services offered there.
Scope of services
eduroam
The wireless LAN for students and employees on campus. Can also be used at many other off-campus locations of other eduroam members worldwide.
- Background information on eduroam
Eduroam(Education Roaming) is an initiative that enables members of participating organizations to access the Internet via WLAN at the locations of all participating organizations using their own account/password or certificate without having to apply for guest access on site.
