    Short company description

    A CONNECTED WORLD IS JUST THE BEGINNING!


    Ericsson is the world’s leading provider of technology and services to telecom operators. Ericsson is advancing its vision of being the “prime driver in an all-communicating world” through innovation, technology, and sustainable business solutions. We now stand on the brink of fundamental innovation opportunities across industries, public services and in private life.

    We are moving from the information society to the Networked Society, where the primary concern is not having access to information, but what benefit you get out of it. It took 100 years to connect 1 billion places and 25 years to connect 5 billion people. The next step is connecting things. Ericsson envisions 50 billion connected devices as a starting point for new ways of innovating, collaborating, and socializing. The result will be simplified processes, higher productivity, real-time information allowing quicker, more informed decision-making or problem solving when relevant, and monitoring.

    The Networked Society changes the logic of how society works. It is our job to take the lead in enabling this, and we are shaping our decisions around that. The ICT industry can help address our world’s major concerns in climate change, health care, education, and more.
