In this session, I will talk about technologies used in IoT world. IoT projects like vehicle fleet management and factory automation force us to play with bunch of different technologies which range from devices, mobile network, cloud to big data and AI. SORACOM is providing series of network services which help developers to get into IoT world, so I will pick up a few real world use cases and explain how customers tackle their challenges, focusing on technology perspective! I hope this talk brings you 'What kind of technologies are required in IoT?', 'What is common challenges today?' and 'What is NEXT?'
