Why 4G is not enough ??
• Key 5G use cases are not economically or technically achievable with the evolution of 4G
- Low latency (1ms) challenges LTE framework and the hybrid retransmission approach
- Connection density (200,000 devices / km²) pressures LTE connection-oriented control plane
- More consistent Quality of Experience (QoE) pushes need for a more flexible optimization
- Simultaneous support for wider range of use cases drives need for a more adaptable network
- High density zones will eventually exceed LTE spectrum bands forces need for new radio access technologies for new
spectrum bands above 20 GHz.
- Need to evolve the security infrastructure to handle a number of attached devices
• 4G LTE
- Evolution continues well after 5G
launch
• 5G
- Low band deployed from 2020 first on
macro cell then on small cells
- High band on small cell follows as 5G
capacity needed

12. What’s driving 5G?
