1 INTERNET OF THINGS IN SPACE IWDK IoT Trends 3 May 2018, DOKK1, Aarhus 3 MAY 2018 ASSOCIATE PROFESSOR

2 2 2 / 0 5 / THE INVENTION OF THE INTERNET 1957, the Soviet Union launched the world s first manmade satellite into orbit 1958: USA government forms NASA and ARPA to develop space-age technologies 1969: Birth of ARPANET 1982: Coca cola vending machine online SPUTNIK : Birth of the internet of Things; more devices connected than humans Sources: MAY 2018 ASSOCIATE PROFESSOR

3 OUTER SPACE - THE NEXT INTERNET Smaller, cheaper and faster Based on commercial of-the-shelf components. Speed and flexibility of construction CubeSat standard (1999) facilitates frequent and affordable access to space Can be designed and implements as a student activity 3 MAY 2018 ASSOCIATE PROFESSOR
