ABSTRACT:
The present invention provides methods, systems, and computer program instructions for enabling a variety of devices, particularly low-power hand-held devices, to travel seamlessly through a networking environment such as that encountered within a building by establishing connectivity to a plurality of network access points. The illusion of seamless network connectivity is provided by having these access points coordinate with a core server to perform user authentication, device address assignment, and handoff services.
