5G Market Drivers ● Internet of Things Wireless Sensor Networks ● Smart Homes ● ● Smart Grid ● Intelligent Transport Systems Virtual Reality/Online Gaming ● Medical Sensors ● Confidential & Proprietary

Diverse Set of Use Cases and Requirements Questions: What’s the commonality? ● What does this mean for the ● design of the protocol? ● Does it make sense to cover all use cases with a single design? What’s the right fragmentation? ● Confidential & Proprietary

Overall Objectives: ITU IMT-2020 ● Higher data rates Peak data rates up to 20 GBps ○ ○ Average user data rates up to 1 GBps Lower latency: ~1 ms ● Higher mobility: Up to 500 km/h ● ● Higher density Traffic density up to 10 Tbps/km 2 ○ Connection density up to 1M/km 2 ○ ● Higher spectrum efficiency Better energy efficiency ● Confidential & Proprietary

Flash-Back: 3G/4G Small-Cell Deployment Forecast Question: Why has it been so slow? ● ● Is technology the problem? Confidential & Proprietary

Small-Cell Deployment Challenges How do we resolve ● these challenges in 5G? ● 5G needs to focus on ease of deployment. 5G needs to answer ● backhaul challenges. Confidential & Proprietary (Source: Fierce Wireless)

Big Data Approach ● The network is complex and dynamic. Improving network KPIs is a great challenge. ● Traditional methods such as drive testing are ● not so representative of actual user experience. Meaningful Goals: ● Focus on Actual User Experience ● Use new technologies such as SON & Machine Learning to optimize network performance. Need open, standardized APIs! ● Confidential & Proprietary

New Paradigm: Spectrum Sharing ● The FCC in the US is opening up the 3.5 GHz spectrum for commercial use. 3-tier approach ● ○ Tier 1: Incumbents, e.g. Navy, FSS Earth Stations Tier 2: Protected Access ○ ○ Tier 3: General Authorized Access ● The migration from Exclusive Use to Spectrum Sharing presents technology opportunities Multiple small operators, ad-hoc or crowd-sourced deployments, or neutral ● hosting, etc. Confidential & Proprietary
