Millions of objects with seamless mobility

3 Requirements for a Next- Gen Mobile Network 1.1. Gigabit- speed wireless broadband Mobile phones that can download full length HD movies in < 5secs MulG- interface capability 1.2. Millisecond latencies Doctors get live video & sensor data from ambulances 1.3. Millions of objects with seamless mobility Fully- autonomous vehicles that can communicate with themselves 3/16

4 So its 5G? Qualcomm Nokia Ericsson 4/16 Huawei

5 Well, not just the G s The fastest Internet and the fastest networks cannot be built by enhancing just the edge 5/16

6 Implicit Core Network Requirements 2.1. FlaMer networks 2.2. Virtual networks and network slicing CommodiGzaGon of network infrastructure 2.3. In- network/cloud- based services Compute/communicaGon tradeoffs Smarter core protocols efficient mulgcast, anycast, broadcast VMs Network slices Physical network Compute Communication 6/16
