Advances in information technologies have made it possible to have Personal Information Service, i.e., personalized multimedia information available anywhere, anytime. Such ubiquitous access requires that a portion of the underlying network infrastructure be wireless. This prompts the debate on what the next-generation wireless network will look like.

To help us in this task, we give an overview of the challenges and some solutions associated with operating a wireless multimedia network.
