5. • Mobile Internet Demand is non-uniform
• Peaks of demand in certain hotspots
can exceed cell capacity
• Baseball stadium deployment – 5500
devices generating 52 Mbps traffic
• Some estimates predict that 12-sector
cell in Olympic park will only be able to
support 30% of mobile Internet traffic
demand
• 12,000 devices attached to WiFi during
Superbowl XLV
• How to scale metro – continuing
splitting macro cells or do something
different?

7. • Future Networks supporting the Mobile Internet will need
to seamlessly integrate a lot more smaller cells
• Shifting from 104 cells to 106 cells will require a change
of mindset and management tools
• Key decisions that need to be considered:
• Whether to use unlicensed, licensed technology or
both?
• If using unlicensed, what does the “SP WiFi” architecture
look like?

10. • Femto Forum defining “Open Femto” to support public deployments
• RAN vendors enhancing RNCs to support Release 8 defined Source
Cell ID to enable macro-to-femto handover
• Release 10 specifications define interference co-ordination capability
between LTE pico and macro
• But...
• NPV analysis indicates that optimum deployments require dense metro
access points
884 WiFi APs with directional antennas used for superbowl coverage
• Metro will benefit from economical wireless (mesh) backhaul
e.g., 1 Route AP for 4 Mesh APs for typical metro WiFi mesh deployment

17. • Mobile networks need to support the integration of many more
smaller cells which offload the legacy macro network
• 3 deployment use cases available:
Bring Your Own WiFi
Licensed Femto
SP Managed WiFi
• Supported by 3 offload different scenarios:
Residential
SMB/Enterprise
Metro/Hotspot
• One converged, EPC-centric architecture can address all use
cases and scenarios
Licensed/Un-licensed, Trusted/Un-trusted, Resi/Ent/Metro
