Ultra High Throughput
Upper Bound to Channel Capacity
For Ultra High Throughput
Higher bandwidth channels
Carrier aggregation
Multiple channels - MIMO
Higher frequency band
Smaller coverage at higher frequency bands

Low Latency
Where does latency come:
– Connection setup
– Over the air transmission
– Network node processing
– Network propagation delay (~ 300 km/ms)
And 5G magic:
– Faster connection time
– Higher throughput
– Control & User Plane Separation (CUPS) architecture
User plan function closer to the customer
Less distance to travel and lower number of nodes to traverse

Ultra Reliability
How is reliability achieved in wireless
– High SNR
– Coding
– Re-transmission
Cost of redundancy
– Lower throughput
– Higher latency
Optimal solutions still being worked out

Massive Machine Type Communication
Massive Machine Type Communication requirements
– Large number of connections
– Long battery life
– Very small packets with minimal overhead
5G magic
– Service oriented architecture
– Network slicing
– Air interface enhancements
Optimal solutions still being worked out

What Does It All Mean Then
It is about business requirements not technology
– Pick components needed for the business requirements
– It’s NOT all or nothing
Cost Benefit economic analysis
– Coverage
– Complexity
Timing
– 5G Capabilities rolled out over a period of time

Summary
5G is a collection of many technologies
Ultra high data rates require higher bandwidth and MIMO
Smaller coverage at higher frequency bands
Fast processing at edge to lower latency
5G has many tools – Pick the right ones!!
