Penn State finally joined eduroam. “eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community.” In other words, Penn Staters can use their Penn State WiFi credentials (PSU ID) to access WiFi services when visiting other eduroam participating institutions. I have used eduroam in Hong Kong, Taiwan, and different cities in US. Find out the participating institutions here.
