More processing horsepower is required

More Processing Horsepower is Required

  • High performance graphics processing

  • Low power, longer battery life

  • Speedy interactions between core processor and device RAM

  • HD video capture and playback

  • 1080p, 30 frames-per-second video

  • Dual displays (for video chat)

  • Vibrant touchscreens

  • External display drivers (HMDI output)

Network Level MarketDrivers

  • 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

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’


Increased capacity and coverage

Increased Capacity and Coverage

Micro

  • Small Cells:

  • 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
