More Processing Horsepower is Required
More Processing Horsepower is also needed at the Basestation level
Network Level Market Drivers
• Capable of delivering all standards-based services (at full throughput)
• Low end-to-end latency
• Cost-effective implementation
• Power efficiency
• Multi-RAT (Radio Access Technology) support,
including 2G and 3G
• Future-proofed support of evolving requirements
• Movement towards ‘small cells’ architecture

What’s next? Dual Core
High-end smartphone devices are expected to have dual core processors by the end of 2010. By 2012, most smartphones will have dual core processors. With a dual core processor different applications can be split between the processors -- saving on battery life and improving processing speed.

Network designers will deploy heterogeneous networks featuring ‘small cells’
The Network: Migration to a Distributed Architecture
Time – Quicker to deploy; limited zoning/permissions – Low site engineering and construction requirements
Cost – Cheaper to deploy and maintain – Lower CapEx – Lower OpEx (primarily due to reduction in lease costs)
Efficiency – Capacity (lots of it) --- exactly where it is needed – Flexibility in site location – Significant capacity gains are possible for lower TCO
