5 This is Broadband everywhere Mobile Broadband Full Mobility High Data Speeds Everywhere Coverage Ericsson Telecomunicações, Lda 2008 Commercial in confidence 5

6 Broadband everywhere adds value the ability to connect the Mobile workforce to the main office with a mobile PC is becoming a critical productivity factor for both private and public sector... EU Commission, June % agrees on the statement Having high speed Internet everywhere is important to me ConsumerLab Internet Frontiers study 2007 Users quickly get used to everywhere access Ericsson Telecomunicações, Lda 2008 Commercial in confidence 6

7 HSPA enables new business Enterprise Business Effective Fleet Management Improved customer services Broadband on the move Attracts more passengers Preferred choice for longer rides Healthcare to all and everywhere Enhanced consultation service to patients Increased number of patients Mobile connectivity increases productiveness Ericsson Telecomunicações, Lda 2008 Commercial in confidence 7

8 HSPA enables cost effective broadband to all... Case Study: Telstra provided HSPA to 98% of pop in 10 months. HSPA 14/1.4 Mbps nation wide, up to 200km cell range Ericsson Telecomunicações, Lda 2008 Commercial in confidence 8

12 Driving forces behind LTE Spectrum flexibility: Use of new, re-farmed or unused spectrum FDD and TDD Variable channel bandwidth Performance: Higher peak rates Higher bandwidth Designed for always on applications from start Cost: IP-based flat Network Architecture (no circuit switched domain) Low OPEX Simpler operation with less to configure and higher degree of self configuration Ericsson Telecomunicações, Lda 2008 Commercial in confidence 12

13 3GPP LTE performance High data rates Downlink: >100 Mbps Uplink: >50 Mbps Low delay/latency User plane RTT: <10 ms Channel set-up: <100 ms High spectral efficiency High Performance Broadcast services Cost-effective migration Ericsson Telecomunicações, Lda 2008 Commercial in confidence 13

14 Key LTE radio access features LTE radio access Downlink: OFDM Uplink: SC-FDMA OFDMA SC-FDMA Advanced antenna solutions Diversity Multi-layer transmission (MIMO) Beam-forming TX TX Spectrum flexibility Flexible bandwidth (1,25 up to 20MHz) New and existing bands Duplex flexibility: FDD and TDD 1.4 MHz 20 MHz Ericsson Telecomunicações, Lda 2008 Commercial in confidence 14

17 What is a Generation? 4G 4th Generation (WRC-07, ITU, global spectrum) IMT-Advanced 3G 3rd Generation (WARC-92 & WRC-2000, ITU, global spectrum) IMT-2000 (WCDMA/HSPA & cdma2000 EV-DO) Evolved 3G (LTE and EV-DO rev C) 2G 2nd Generation (1980 s, CEPT) GSM, PDC & cdmaone 1G 1st Generation (1970 s, national spectrum) NMT, AMPS & TACS A Generation is defined by a technology and spectrum harmonization event Ericsson Telecomunicações, Lda 2008 Commercial in confidence 17

18 IMT-Advanced - more bandwidth needed Increased voice traffic Increase in information based traffic New capable services require high data rates -> > need for an enhanced radio technology, providing yet higher peak data rates and shorter delays IMT-Advanced Goal: Goal: MHz MHz channels Speeds of of up up to to 1 Gbps Gbps IMT-Advanced cannot only be deployed within the current spectrum Ericsson Telecomunicações, Lda 2008 Commercial in confidence 18

19 Conclusions Demand for Mobile broadband HSPA, already a huge commercial success HSPA on par with fixed broadband and evolving (40-80Mbps) LTE for increased performance (>150Mb/s) and cost efficiency HSPA, 70% of mobile broadband subscriptions 2012 Ericsson Telecomunicações, Lda 2008 Commercial in confidence 19
