Mobile Broadband Journey
• Wireless is the most personal and pervasive mean to access Broadband
Services
• The Operator’s challenge is to continue enhancing the User’s
experience

Why LTE
Enhanced network capacity
• Architecture renewal with Full IP focus
• Multiband scalable Radio Technology
Improvements on connection scalability
• From Smartphone to the “network of the things”
• Heterogeneous NW – from macro site to femto
Additional wireless resources
• More Spectrum (multiband) more efficiently used…
• Wide area pervasive coverage requires low bands (<1GHz)

Beyond LTE: Never Stop Evolution
LTE-Advanced
• Wider bandwidth for higher performance
• Exploiting more sophisticated Radio Transmission schemes
• Self-Organising network to efficiently handle heterogeneous network
• Relay to boost pervasive coverage

Conclusion
• Mobile Broadband demand will put under stress of the available capacity
– Technology will be the enabler of Mobile Broadband but its success is rapidly
exposing its limits
• Long-term success is not based on any one innovation and it is not based on
any one company
– It is based on a harmonic growth of the entire data delivery chain
– It is based on how the industry works together
–Network operators
–Equipment manufacturers
–Device makers
–Software providers
–Regulators
