eduroam is a secured wireless network that allows students, faculty and staff to use their home institution's credentials to access wireless network services, when visiting other eduroam participating institutions without having to set up a guest account.
Drexel, Temple, Haverford, Bryn Mawr and Swarthmore are participating institutions.
Visitors to Penn from other institutions that participate in eduroam should obtain configuration instructions and installation software from their home institution.
