Massive Densification• Increased expectations

• Multi-Dwelling & Multi-AP deployments• Community Wi-Fi & Wi-Fi First Services

Spectrum Sharing scenarios• Unlicensed band – LTE-U, LTE-LAA

• Other bands• Coexistence with cellular and other systems

Internet of Things (IoT)• Wi-Fi connection today and central role moving forward

becomes critical

Multiple APs in a Home• Filling in coverage holes• Extender, Mesh arrangements• AP auto-configuration• Mobility, client steering to maintain

continuous coverage

Entrenched Presence in Homes, Enterprises• Gateway technology for broadband – today.• Ideal choice for IoT Gateway - tomorrow• Many home appliances shipping with Wi-Fi now• Works well for bandwidth-hungry, power-tethered

appliances

IoT-tailored Wi-Fi variants emerging• 802.11ah(HaLow)forlonger-range,morepenetrative

The Interference Challenge…

• DenseDeployments

• Managed&UnmanagedNetworks

• Resultinginsub-optimalQoE

• NotjustWi-Fi

10

Congestion–HighLatencies EvenWorse– Interference,Collisions

Without Proper Coordination

11

Coexistence rules, obeying the etiquette• Avoid “stomping” on other users• Listen Before Talk, Dynamic Frequency Selection, Discontinuous

Transmission

Harmonized Radio Resource Management/ SON• Minimize / mitigate interference and congestion• Optimal resource allocation to maximize QoE• Continuous optimization

Coordination with other access technologies• E.g. ZigBee, Bluetooth
