  • BLUECOM+: Cost-effective broadband communications at remote ocean areas
    Publication . Campos, Rui; Oliveira, Tiago; Cruz, Nuno; Matos, Anibal; Almeida, José Miguel
    The ocean and the Blue Economy are increasingly top priorities worldwide. The immense ocean territory in the planet and its huge associated economical potential is envisioned to increase the activity at the ocean in the forthcoming years. The support of these activities, and the convergence to the Internet of Things paradigm, will demand wireless and mobile communications to connect humans and systems at remote ocean areas. Currently, there is no communications solution enabling cost-effective broadband Internet access at remote ocean areas in alternative to expensive, narrowband satellite communications. This paper presents the maritime communications solution being developed in the BLUECOM+ project. The BLUE-COM+ solution enables cost-effective broadband Internet access at remote ocean areas using standard wireless access technologies, e.g., GPRS/UMTS/LTE and Wi-Fi. Its novelty lies on the joint use of TV white spaces for long range radio communications, tethered balloons for lifting communications nodes high above the ocean surface, multi-hop relaying techniques for radio range extension, and standard access networks at the ocean. Simulation results prove it is possible to reach radio ranges beyond 100 km and bitrates in excess of 3 Mbit/s using a two-hop land-sea communications chain.

  • Strengthening Marine and Maritime Research and Technology
    Publication . Silva, Eduardo; Martins, Alfredo; Dias, André; Matos, Aníbal; Olivier, Augustin; Pinho, Carlos; Sá, Filipe Aranda de; Ferreira, Hugo; Silva, Hugo; Alves, José Carlos; Almeida, José Miguel; Pessoa, Luís; Ricardo, Manuel; Cruz, Nuno; Dias, Nuno; Mónica, Paulo; Jorge, Pedro; Campos, Rui
    INESC TEC is strongly committed to become a center of excellence in maritime technology and, in particular, deep sea technology. The STRONGMAR project aims at creating solid and productive links in the global field of marine science and technology between INESC TEC and established leading research European institutions, capable of enhancing the scientific and technological capacity of INESC TEC and linked institutions, helping raising its staff’s research profile and its recognition as a European maritime research center of excellence. The STRONGMAR project seeks complementarity to the TEC4SEA research infrastructure: on the one hand, TEC4SEA promotes the establishment of a unique infrastructure of research and technological development, and on the other, the STRONGMAR project intends to develop the scientific expertise of the research team of INESC TEC.
