Key Challenges

OPEX GROWTH• Manual intervention

• Siloed & fragmented solutions

• Static deployment models

INTERFERENCE• Lack of multi-

vendor coordination

• Managed & unmanaged access points

• Densification complexity

SCALABILITY• Insufficient legacy

equipment models

• Multiple dimensions – location, loading, service type, reliability

REVENUE• Unclear business

models and revenue

• Lack of consolidated framework for service enablement

The Interference Challenge…

• Dense Deployments• Multi-dwelling units• Indoor-outdoor metro deployments• Community Wi-Fi

• Managed & Unmanaged Networks• Unmanaged APs using same channels

• Resulting in sub-optimal QoE• Congestion due to excessive resource contention• Hidden node issues• Collisions, interference, packet losses & error rates

• Vendor-specific solutions• Solving problem in different ways, and to different

extents• Lack of multi-vendor solutions

Amplified by Emerging Hetnet Scenarios

Solutions Must Incorporate Best of Both Worlds

• Cellular Sensibility• Coordination, QoE-awareness

• Wi-Fi style self-organization• Plug-n-play, automation,

simplicity

• Scalability and high reliability

Solving LTE-LAA/LTE-U Interference Challenge

• Coexistence rules, obeying the etiquette• Avoid “stomping” on other users

• Listen Before Talk, Dynamic Frequency Selection, Discontinuous Transmission

• As critical – Harmonized RRM / SON• Minimize / mitigate interference and

congestion

• Optimal resource allocation to maximize QoE

• At startup, as well as continuous optimization

• Radio environment monitoring, mapping and visualization tools
