This page intentionally left blank Preface Across the IoT, Autonomous Driving (ADAS), edge compute, and service provider ecosystem, 5G is understood to not "just" be about enabling a faster data connection to the end-user device. 5G evolves both existing technologies (radio access and home networks) while laying the foundation for new applications across consumer and industrial automation with the self-driving car being a prime example. Even though 5G is very much hyped since 2
