1 Impact of IP on Mobile Communications David Caspari Vice President Asia Pacific Service Provider Feb 24, 2005 THIS IS CISCO ON THE MOVE 1

2 The Vision of Mobility Delivering Operational and Service Benefits 2

3 The Vision of Mobility The Mobile Network Impact of IP Access Agnostic infrastructure to deliver anytime, anywhere, any device access Improve Network Efficiency to eliminate capacity bottleneck; SMS, MMS, Signaling Transport, Voice Packet Convergence to support multi-service / multi-access Intelligent Information Network to drive new Services, Applications & Content 3

4 The Vision of Mobility A Combination of Radio Technologies Mobility The Increasing Relevance of IP for Mobility Solutions High Speed Fixed Walk Vehicle Vehicular Rural Vehicular Urban Pedestrian Nomadic Fixed urban Personal Area Indoor GSM GPRS DECT BlueTooth 3G/UMTS HSDPA EDGE Flash OFDM WLAN (IEEE x) Dial, ISDN ADSL E1 VDSL, E3 IEEE e IEEE d LMDS (SkyWeb) Metro Ethernet, SDH, DWDM Mbps User data rate 4

5 The Vision of Mobility Cisco s Architectural Framework Seamless Roaming RAN Optimisation Signaling over IP PSTN Mobile Operator GGSN/ PDSN Intelligent Internet Edge IP Foundation Enterprise Mobile IP VPN WLAN at Home Office Access Points (IEEE b) DSL Cable PWLAN AAA Service Selection SESM Content Services Cellular Infrastructure for ubiquity Wireless LAN public and private Mobile IP maintains session VPN extends Enterprise Network IP MPLS Core Personalization/ Policy Internet Third Party Applications 5

9 RAN Optimization Mobile Service Provider Opex Analysis Source: Yankee Group Jul 2003 Bottom Line - RAN backhaul accounts for more than 50% of total OpEx spend making it an obvious target area for cost reduction 9

10 RAN Optimization The cell site of the future is IP connected WCDMA-TDD 1xEVDO WiFi WiMAX Other 4G GSM/ CDMA/ TDMA BTS Ethernet ATM UMTS Node B (R4/R99) HSDPA Enterprise IP TDM IP Decreases OPEX (Compressed Abis over IP, Alternative Backhaul, Capacity sharing) IP Expands Capability for New Service Delivery (RANs for new services, WLAN, Fixed Wireless, 3/4G data overlays) Cell Site Routers for Investment Protection BSC UMTS Node B (R5/R6) T1/E1 Optimized Abis/Iub over IP Alternative Backhaul: Metro Ethernet DSL Cable /20 Power line Cell Site Access Network IP TDM Ethernet ATM RNC Cisco Mobile Exchange BSC/RNC Site Mobile Internet Edge 10
