What’s next? Dual Core

High-end smartphone devices are expected to have dual core processors by the endof 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
