Proprietary and Confidential12
Between 50 to 100 million people in the world have mobile phones, even though they do not have electricity at homeD
Market growth drivers
Explosion in mobile data
Global mobile data traffic is nearly tripling every year
Proprietary and Confidential13
Smart-phones – 13% of handsets but 78% of global traffic.
Mobile video traffic is over 50% of the world's mobile data traffic
Market DriversBandwidth Hunger is Ever Increasing
Everything gets mobile - We expect wireline experience from the wireless networks
Video
Video applications are the key drivers(HD, HD 3D)
Cloud Computing
From local to remote IT infrastructure – taking the office with you

� Urban core Overlay approach-
– Macro cell for voice & HSPA
– Small cell for high speed data
� Street level deployment
� Low cost, Plug and play
� CoMP (3GPP R9) for efficient spectrum usage
Proprietary and Confidential26 26
� “Non-technology” hurdles to overcome for deployment!
Small Cells Backhaul -
• Connect via Macro sites
• Any Topology
• Mix of backhaul technologies
• Very small form-fit• Mid-High Capacity• Low TCO but Unlicensed
• High capacity• Low interferences • Licensed
• No antenna alignment• Low capacity
