10 Vision Vision Build a state of the art information infrastructure in the world Create an environment to use high-quality multimedia services Prepare core foundation of IT industry growth momentum Goal Build an Integrated network with the bandwidth of 50~100Mbps that can offer seamless multimedia services to 20 million wired or wireless service subscribers Wired (50~100Mbps) Wireless (50~100Mbps) 1,500,000 4,500,000 10,000, ,000 3,500,000 10,000,

11 Driving Forces Towards BcN Need of change communication market architecture(need of New value added service) Saturation of both Fixed and Mobile telephone services Need of Integrated (Fixed+Wireless) and Convergence (Telecom+Broadcast) Need of New Service Paradigm Increase of Service requirements (Flex. of Access, Diversity of Service etc.) Increase of High Quality services Need growing energy for IT Business Preparation of New Revenue Stream based on IT Business Development of new high-tech and market

12 BcN versus NGN BcN (Broadband Convergence Network) NGN (Next Generation Network) 2002 NGN, 2003 NGcN, 2004 BcN Convergence of Broadcasting and Telecommunication Continuation of GII(1993)concept NGN 2004 Project in ITU Terminology Time for Convergence of Broadcasting and Telecommunication NGN related Recommendations in ITU are still conceptual

13 Realization of BcN Realize Leveraging Engines STEP 1. Evolve Broadband Access Network STEP Add intelligence to Edge Network STEP Add QoS to Core Network STEP 3. Home Networking through Broadband Final STEP. Broadband convergence Network

14 Realize Leveraging Engines Network Evolution (Access Network, Edge Network, Core Network) Service & Application Platform Communications Contents Commerce Control Computing Service & Application Layer AAA, Session, Policy, Security, Mobility Wireless Access CDMA, 1xEVDO WCDMA 2.3GHz Edge Service Node Core Network Best Effort Premium Edge Service Node Wireline Access xdsl, Ethernet W-LAN FTTH CATV/HFC Network Layer

15 STEP 1. Evolve Broadband Access Network(1) Fixed broadband needs Higher Speed - Services : High quality VoD, T-commerce, Telecom-Broadcasting converg ence, Tele-medicine, Virtual reality, Evolution phase - VDSL : 13/20Mbps 80Mbps - FTTx : FTTC-VDSL / FTTC-Ethernet FTTH - HFC : 4Gbps, Triple-play service <1M 3M 6M 50M 80M 100M ADSL (CATV) FTTC more than 3Km Twisted copper line APT FTTC more than 2Km VDSL VDSL Present Status in Korea ADSL+/2+ FTTC more than 1Km FTTH

16 STEP 1. Evolve Broadband Access Network(2) Wireless broadband needs Higher Speed, Mobility & more Coverage IP based integrated network for high quality convergence services through dynamic accesses Wireless LAN(Netspot) Speed: 11Mbps 2.4GHz(IEEE802.11g) 5GHz*IEEE802.11a)? Mainly for Indoors House SOHO Airport University Hotel xds LEnterprise A A P P Hot Spot A A P P Hot Spot 2.3GHz Hot zone 2.3GHz Portable Internet(WiBro) Terminal Mobility(over 60km/h) Coverage: 400~500m(dense) 3~4km(suburban) Speed: 1~2Mbps? Mainly for Outdoors Internet
