The Mobile Internet is growing fast
Over 5 billion mobile subscriptions • 1.54 billion mobile devices shipped in 2010
• 21% of these were smartphones
• 57% of these were GSM only
• 48% of UK sales were smartphones
• 350 million mobile Facebook users, 44% of total
• YouTube mobile gets over 400 M views a day (up 3x year/year), representing 13% of their daily views
• By 2020, 70-80% of mobile terminals will be smart devices
• Globally, 80% of web access will be mobile by 2020

Broadband
everywhere
LTE
on low
frequency
bands, e.g.
digital dividend
High-Speed
Broadband
Capacity for all
LTE
on large
frequency bands,
e.g. 2.6GHz
10-20ms latency
173 Mbps peak data rate
Downlink: OFDMA
• Improved spectral efficiency
• Reduced interference
• Very well suited for MIMO
Uplink: SC-FDMA
• Power efficient uplink increasing battery lifetime
• Improved cell edge performance by low peak to average ratio
• Reduced Terminal complexity
Simple to adapt to different bands

LTE deployment:
- new bands or refarming
- Ideally, large contiguous spectrum
blocks
- “coverage” spectrum < 1 GHz
- “capacity” spectrum 2 GHz and
higher

Heterogeneous Networks cannot be handled in the traditional way
Wide Area • Majority of
cells • Beyond
300 m
Medium Area • Share
growing • 100-300m
Hot spots • Share
growing • 10-100m
Indoor • Emerging • < 10m
LTE networks will coexist in parallel with existing 2G & 3G networks for many more years
The myriad of cells and layers requires smart optimization and network management solutions
Smaller cells will enable offload of local high capacity traffic from wide area network
Multi-radio traffic and interference management are needed to manage traffic growth
