What is the eduroam service?

The eduroam service (or JANET Roaming Service) allows users visiting participating institutions to access network resources using the logon credentials from their own institution. 

eduroam allows users guest access at other academic locations without the need for guest accounts.

The level of network access a visitor has is set by the host university and may vary from one university to the next. More information about the eduroam service can be found on the eduroam website.

All participants (institutions and individual users) are bound by the Janet Roaming Policy. Please also refer to the University Acceptable Use Policy (IT facilities).
