  1. Evolving the Evolved Packet Core Jim Johnston CTO, Communications Convergence Processing Mindspeed Technologies, Inc.

  2. Mobility + Content Innovative New Platforms New Networked Applications + = Explosive demand for Mobile Broadband

  3. Powerful Consumer Devices put Processing Horsepower at the Edge of the Network • 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) (photos courtesy of Samsung and Lenovo) Epic 4G smartphone ,Galaxy Tab (Samsung), Skylight Smartbook (Lenovo)

  4. An Explosion in Mobile Data Traffic 3,600,000 • This surge in mobile data and video coincides with: • A strategic move away from separate (circuit- switched) voice and (packet-switched) data networks • The migration to 4G LTE networks with an all-IP core • A move towards heterogeneous networks featuring macrocells, microcells, picocells and femtocells Terabytes Per Month 1,800,000 2009 2010 2011 2012 2013 2014 Source: 2010 Cisco VNI Mobile pictured: Samsung Seek (courtesy of Samsung Mobile)

  6. The Network: Migration to a Distributed Architecture Metro Urban Business Residential High-Density Subs Femto Business Enterprise Femto Macro Micro Pico 50 200 10 400 1200 Business Metro Business Supported Subscribers Network designers will deploy heterogeneous networks featuring ‘small cells’

  7. The Computational Complexities of 4G are Magnified Evolving mobile standards will drive massively higher data rates • Advanced baseband processing techniques • Adaptive beam forming • Adaptive modulation • MIMO antenna systems • Space Time Coding (STC) • Digital RF processing

  8. Increased Capacity and Coverage • Why Small Cells? Micro • 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) • More options for cost-effective backhaul • Efficiency • Capacity (lots of it) --- exactly where it is needed • Flexibility in site location • Significant capacity gains are possible for lower TCO Pico Femto

  9. Processor Complexity in Evolved IP Networks > 900 million Silicon Complexity number of transistors 300x 300 million < 3 million Software Complexity lines of code 20 million 2000x 2 million < 10,000 Dial-Up Modems VoIP 4G Baseband 1995 2005 2010 Source: Mindspeed Technologies

  10. Next-Generation Base Stations Must Change to Support the (All-IP) Evolved Packet Core • Must be capable of delivering all standards-based services (at full throughput) • Low end-to-end latency • Cost-effective implementations • Power efficiency • Multi-RAT (Radio Access Technology) support: including 2G and 3G • Future-proofed support of evolving requirements • Movement towards ‘small cells’ architecture (macro-micro-pico-femto)

  11. Video is the Common Driver for User Equipment and Network Upgrades Smartphones , with 20% market share, are responsible for over 80% of mobile traffic usage. Almost 66 percent of the world’s mobile data traffic will be Video by 2014. Source: Informa Telecoms & Media Source: Cisco Visual Networking Index 2010
