LTE Is Deploying Now! Technology Trials 3GPP R8 Standards NEP Product Development Commercial Rollouts 2008 2009 2010 2011 LTE Field Trials Rollouts led by CDMA2000 operators 3G operators will continue HSPA deployments

3G Roll-Out Lessons Learned “ Build it and they will come” But how fast? Nationwide network build out = cash burn Indoor coverage Higher spectrum = poor indoor signal penetration ~60% mobile traffic originates indoors Deliver where it’s needed 100Mbps data rates in home, office, café, airport… Leverage existing 3G HSPA for nationwide coverage

LTE Deployment Challenges Service delivery over “All-IP” networks Securing “All-IP” networks Spectrum availability Aligning investment with demand DPI Femtocells

DPI’s Role in Mobile Broadband Look inside packets and quickly decide… Drop? Modify? Prioritize? Security, Traffic Management IDS / IPS / firewall Security gateway Subscriber traffic shaping P2P blocking Content caching Lawful intercept Revenue Growth, Differentiation Tiered subscriber bandwidth Voice quality Application-based QoS Market intelligence gathering Mobile targeted advertising Caching – mobile video DPI = Deep Packet Inspection
