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?

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!

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
• pportunities
• Multiple small operators, ad-hoc or crowd-sourced deployments, or neutral

hosting, etc.
