Eduroam is a faster and more secure service.
You will also find that if you travel around to other Universities (and coming soon other NHS sites) you will be able to pick up their Eduroam access using your own Cardiff University credentials.
NHS users will find that their sites are increasingly covered by Eduroam. Morriston and Singleton Hospitals are already live. We will post up details of other NHS sites in Wales as we become aware of them.
There is an eduroam app which will locate where your nearest Eduroam hotspots are.
