11 LTE Concept

12 What is LTE? A common evolution path Long Term Evolution (LTE) is the next generation broadband wireless technology for 3GPP and 3GPP2 networks Enabling new applications, lowering cost Peer to peer applications requiring high throughput Online gaming Flat fee trend OFDMA MIMO Flat IP Robust modulation in dense environments OFDMA (DL) / SC-FDMA (UL) Increased spectral efficiency. Simplified Rx design Cheaper UE Scalable - go beyond 5 MHz limitation Increased link capacity Multiple-input, multiple-output UL& DL. Collaborative MIMO (UL). Overcome multi-path interference Flat, scalable Short TTI: 1 ms (2 ms for HSPA). Backhaul based on IP / MPLS transport. Fits with IMS, VoIP, SIP A taste of 4G based on highly efficient technologies * Orthogonal Frequency Division Multiple Access

13 LTE: Compelling performance 65 ms Latency Reduction 50 ms 50 ms Low latency enables fast channel adaptation therefore allowing high speed applications HSPA HSPA+ WiMAX Higher Peak throughput (Mbps) 10 ms LTE 326 DL HD TV User created content Multi-screen Gaming 173 DL More 5 UL 14 DL HSPA (5MHz) 11 UL HSPA+ (5MHz) 42 DL 9 UL 36 DL WiMAX (10MHz) 55 UL LTE MIMO 2x2 (20MHz) 86 UL LTE MIMO 4x4 (20MHz) High peak throughput enables rich content applications over LTE

14 LTE Transforms Wireless Access and Core Networks to All-IP 2G/3G controller LTE End-to-end IP (All-IP) Clear delineation of control plane and data plane Simplified architecture: flat-ip architecture with a single core

15 QoS evolution 2G Conversational Streaming 3G Interactive Background QoS evolution From: 4 classes in UMTS and CDMA To: 9 classes (QCI) in LTE
