8 What about 5G?
5G will answer customer expectation Coverage Data Rate Connected Objects the customer s expectation is increasing : a high quality connection everywhere (home, transports, rural, ) customers ask for a more affordable basic internet access (50 Mb/s) new usages, like virtual reality or augmented reality, requires very high bit rate > 1Gb/s some objects, like driverless vehicles, drones or robots, call for low latency 1ms low-end, low energy consumption sensors will be massive and should be handled properly
THROUGHPUT New usages will emerge 5G is truly going to revolutionize usages 10 Gbps 360 TV&Video Cloud AR/VR in mobility 1 Gbps 100 Mbps 10 Mbps 1 Mbps Industry & Robots 100 Kbps 10 Kbps Sensors 1 Kbps Actuators 100 bps Smart Agriculture Smart City Autonomous Car Remote Operation 10 1 s 100 ms LATENCY 10 ms 1 ms

Main Challenges for 5G 1. How to meet network requirements of 5G services? Network Slicing 2. How to simplify 5G Network Function Interfaces and protocols? Service Based-Architecture 3. How to improve QoS, Policy usage for 5G services? Control and User Plane Separation
14 1- Network Slicing
How to achieve a perfect network? The One-size-fits-all model is no longer adapted to 5G 5G 4G 15
Network Slicing Network partition Slice for a usage scenario Slice: collection of Network Functions to support a 5G Service(s) 1. Enhanced Mobile Broadband >1Gb/s 2. Massive Machine Type Com IoT >100 000/km2 3. Ultra Reliable and Low Latency Com <5ms 16 J. Chawki Orange ONS 2018
