The objective of this project was to implement and test an integrated 4G architecture composed by diverse technologies, such as Ethernet, 802.11 (infrastructure and ad-hoc), and 802.16 and DVB-T. The mobile terminals is able to choose to connect to one (or more) of the available access technologies, depending on the services being requested, economical issues and specific user preferences. Moreover, mechanisms are proposed for the users to move and change between different and heterogeneous access networks without disrupting the connection and without service degradation. Finally, while connected to one of the technologies and while moving between networks, mechanisms are presented for the delivery of a multitude of services, legacy and multimedia, unicast and multicast (and broadcast), with a guaranteed quality of service.
 
Note that no clear business models exist at this moment on how to integrate these diverse technologies (from the broadcasters, cellular operators, and Internet service providers). It is nevertheless considered that video and TV entertainment services (MTV, Eurosport) will be of special interest in these environments.
