Summary

Nomadic use refers to a usage pattern of the Internet with intermittent access. Key to a user experience of anytime, anywhere access to the Internet and its applications are scalable, secure, and seamless access methods. Federated identity plays an important role in providing such a user experience in the presence of multiple-access networks and applications offered by different operators. Nomadic use requires some form of context awareness to provide services that are tailored to location, access method, and device.
