5G: What Is It and What New Applications Are Driving Its Formation?

Cellular systems are growing into their fifth generation (5G). Trials of 5G technologies are already underway and extensive deployments of 5G are expected in the coming years. In this webinar, I explain several new revolutionary applications of cellular communication, which place new requirements on the design of 5G. These applications involve vehicular- and aerial-to-everything communications for mobile robots, or ultra-reliable low rate communications in the context of IoT. Then I describe different technical elements of 5G enabling these new applications. Some examples of these technologies are massive MIMO, millimeter wave communication, or network slicing. Finally, I categorize these technologies based on how much they disrupt 4G thinking.
