4 Operator Strategies for an LTE Deployment 3 Categories for LTE Deployment of Operator Data Only Services on LTE - Data-only service used for high-speed mobile broadband - Quick deployment of LTE access without requirement of voice core solution - Consideration for the interoperability with 2G-3G data - Wireless dongles, netbook, Air cards, etc Data Only Services on LTE with 2G-3G Voice - Voice is still major revenue generator for wireless operators - Quick deployment of LTE access without the need for an entirely new voice core solution - CSFB, SVLTE must be considered depending on the current network deployment strategy Data and Voice services on LTE - Wireless data All-IP technology based on IMS - Need full LTE Coverage with new voice core solution - Multiple new functions is required to incorporate with IMS into LTE ecosystem

5 Operator Considerations of LTE migration Efficient use of available resources for a smooth deployment Spectrum Considerations - Need to secure additional spectrum to enhance subscriber experience and new type of service - Allocate new spectrum and refarming of existing spectrums for LTE Service - Consideration for the phase out and refarming will be difficult issue Access Network Equipment Considerations - Increase coverage and capacity, and reduce interference for seamless services - Fast network deployment for the Time to Market - Reduce the Capex and Opex through Antenna sharing Core Network Equipment Considerations - Reuse and integrate as much of their existing core network to reduce the Capex and Opex - Reduce operation complexity by combining in single nodes - Maximizes network performance by reducing the number of external interfaces

7 Network Evolution and Vision Motivation of KT Network Evolution SMART Work & Life Smart Government Smart Grid Smart Healthcare Smart Office Smart Home Smart TV SMART Network SMART Terminal Self Management High Spectrum Efficiency Guaranteed QoS/QoE Context Awareness Green Energy Mobile Cloud Multi Screen Connect All Things UI Innovation Always Best Connected P2P Data Explosion and Paradigm Shift

8 Network Evolution and Vision History of KT Network Evolution

9 Network Evolution and Vision Mobile Wonderland - 3W ( 3G(WCDMA)+LTE, WiMax(WiBro), WiFi ) Strategy

10 Network Evolution and Vision Vision : Simple, Smart, Strong Network Simple Network Smart Network Strong Network Simple FMC Architecture for Emerging Service Cost Efficient Network Operation Single Node for Simple Network Smart Network for QoS / QoE Smart Node/Gateways and Open API Easy to Manage and Optimize the Network Trustworthy Networking Robust Networking

11 Network Evolution and Vision Simple Network BackBone Network IP BackBone Network Integration - FMC for Emerging Services - Cost Efficient Network Operations - New Business Model by Network Resource Management

12 Network Evolution and Vision Simple Network Integrated 2G/3G and 4G Functions in a Single Node - Reduce the signaling overhead - Distribute session management - Reduce the Capex and Opex

13 Network Evolution and Vision Smart Network Smart Network Platform - Smart Gateway - Smart Node - Open Network Ecosystem

14 Network Evolution and Vision Strong Network Strong Network Configuration - Dual-Homing is increasing service stability - Common User DB of AS is increasing service flexibility - Fixed and Mobile subscribers can be connected to Unified IMS platforms

15 1 LTE Strategy and Considerations 2 KT s Network Evolution and Vision 3 KT LTE WARP

16 Why LTE WARP?

17 What is LTE WARP - World s first cloud based LTE enhancement solution

18 What is LTE WARP - Cell Virtualization

19 Evolution of Mobile Access Network Access Network 3G CCC LTE WARP LTE WARP+ Coverage Macro Cell Stand Alone Capacity Small Cell Cloud Personal Cell 500x + 1,000x 200x 54 [TB/month] 1 Smart Control 100x '09.1 '10.1 '11.1 '12.3 '12.12 ' Core Network

20 Evolutionary Phases of CCC Phase 1 (Separation) Phase 2 (Centralization) Phase 3 (Virtualization) Macrocell Base Station RU RU Core N/W DU RU Core N/W DU Core N/W DU Cloud Processor Channel Card Amplifier Filter Separation of DU-RU 4G WiMax DU Centralization 3G DU Virtualization LTE WARP * DU: Digital Unit, RU: Radio Unit

21 Benefits of LTE WARP - Cell Edge Speed Improvement Resource Allocation based on 144 Cell Group Data Speed LTE Resource Allocation based on Individual Cell Interference Interference

22 Benefits of LTE WARP - Plug-in Scalability DU Centralized Office RU WiMax 3G LTE LTE 3G Optic Fiber WiBro Optic MUX LTE LTE * CAPEX of Mobile Backhaul 3G WiBro 3G WiBro

23 Benefits of LTE WARP - Increase Capacity and Reduce CAPEX & OPEX * Seoul Metropolitan (All other conditions are the same) ** OPEX: Maintenance + Site Rental + Electricity

24 Key Network Technology for Beyond LTE-A - Beyond LTE-A, we should focus on the technologies that maximize overall network capacity as well as increasing spectrum efficiency
