  7. 5. Sustainability Impacts of Satellite Internet : Digital Inclusion vs Environmental Sustainability

    Master-uppsats, Uppsala universitet/Informationssystem

    Författare :Lana Abdallah; [2022]
    Nyckelord :;

    Sammanfattning : An estimated 450 million people globally do not have access to a fixed or mobile broadband signal. Recently satellite communication companies announced the concept of Megaconstellations which are large networks of inexpensive low Earth-orbiting satellites. These constellations aim to provide internet access across the planet. LÄS MER
