This project aims at developing a wireless broadband network infrastructure within the N.C.S.R. ‘Demokritos’ facilities in order to cover mainly the needs of the visitors and the mobile users. This means constant and uninterruptible access to the Internet and its services. In addition, the project aims at the development of an e-science web portal which will roadmap the scientific-research activities in Greece. Finally, it will provide web-casting services with the broadcast of scientific activities via video to the users of the e-science web portal.
