eduroam.es
The eduroam.es service means users can travel from one institution to another that also has the service deployed and enjoy wireless connectivity at all times.
The main advantage that this service offers is that users can connect to the host institution's wireless network transparently, using their home organisation's login details as if they were in their own office and without having to request an account in the institution they have travelled to.
The institution must be connected to the eduroam service so that users from another institution can automatically operate on their network. This service is currently available in more than 120 institutions countrywide and in hundreds of institutions in Europe and other parts of the world.
