1 Capital Markets Day New York May 11, 2006 Håkan Djuphammar V.P. R&D Systems Management Cellular Evolution Agenda Overview of cellular standards Evolution of and commercial deployments LTE ( Super 3G ) Status on test beds, etc.

2 Evolution of cellular standards EDGE, HSUPA DTM MBMS MBMS EDGE + Ph2 DL 480 kbps CS+PS Multicast Broadcast MBMS + DL 14.4 Mbps UL 5.76 Mbps Multicast Broadcast >40 Mbps RTD <20 ms LTE ( Super 3G ) OFDM TDD/FDD 3GPP 1xEV-DO Rev A Rev B Rev C DL 3.1 Mbps UL 1.8 Mbps GSM Multi carrier WCDMA LTE 3GPP2 CDMA Improving the track SPEED CAPACITY REDUCED DELAY Higher bit rates: Up to 40 Mbps downlink Higher bit rates: Up to 10 Mbps uplink times improved system capacity DL/UL times more VoIP users 2 times improved broadcast/multicast capacity Quicker response time with interactive services STANDARDIZED Integral part of WCDMA (3GPP Rel 7) Network Coverage Short time to market with existing sites

3 VoIP over capacity roadmap Technology potential % of CS R99 voice capacity DCH 64 without ROHC without ROHC 3GPP Rel. 6 with ROHC + improved scheduler DL Rel. 7 estimate UL DL + efficient signaling & protocols Optional GRAKE2 + GRAKE2 5 MHz System Capacity Simulated Estimate 3GPP Target Downlink\Uplink LTE 5 MHz 3GPP Evolution targets HSDPA is live and commercial December 6th, 2005 Commonly provides users with 1 Mbps download speeds

4 HSDPA devices available today Terminal availability (HSDPA) Available today: Volume PC cards, 1.8 Mbps Suppliers: Novatel, Sierra Wireless, Option, Huawei Proof-of-Concept Ericsson Fixed Wireless Terminal 2Q06: First handsets, 1.8 Mbps Suppliers: Samsung, BenQ/Siemens First PC cards, 3.6 Mbps 2H06: Volume handsets, 3.6 Mbps 2nd generation FWT (from Ericsson) for commercial use 1H07: PC cards and handsets, 7.2 Mbps DL Enhanced Uplink support, 1.46 Mbps Handsets and PC cards HSDPA bit rate Live network, March 2006, mobile drive route 1.8 Mbps % 20.00% 90.00% 18.00% 80.00% 70.00% 60.00% Median bitrate: 1200 kbps 16.00% 14.00% 12.00% C.D.F % 40.00% 10.00% 8.00% P.D.F % 6.00% 20.00% 4.00% 10.00% 2.00% 0.00% HSDPA throughput [kbps] 0.00%

5 Evolution of cellular standards EDGE, HSUPA DTM MBMS MBMS EDGE + Ph2 DL 480 kbps CS+PS Multicast Broadcast MBMS + DL 14.4 Mbps UL 5.76 Mbps Multicast Broadcast >40 Mbps RTD <20 ms LTE ( Super 3G ) OFDM TDD/FDD 3GPP 1xEV-DO Rev A Rev B Rev C DL 3.1 Mbps UL 1.8 Mbps GSM Multi carrier WCDMA LTE 3GPP2 CDMA2000 What is OFDM? OFDM = Orthogonal Frequency Division Multiplex Fundamentally just a modulation/multiplexing method Single-carrier transmission ( e.g. WCDMA, cdma2000 ) e.g. 5 MHz ( WCDMA ) Typically several 100 sub-carriers OFDM ( multi-carrier transmission ) Sub-carrier spacing ( a few khz to a few 10 khz )

6 Frequency hopping and OFDM time power frequency One OFDM carrier What does bring compared to? Higher end-user bitrates by wider carrier bandwidth - Over 100 Mbps in a 20 MHz carrier bandwidth. Spectrum flexibility and smooth migration into legacy bands - Flexible bandwidth 1.25 MHz 5 MHz 10 MHz 15 MHz 20 MHz Spectrum availability - Support for operation in both FDD and TDD dedicated spectrum FDD-only Combined FDD/TDD TDD-only f DL f DL f DL/UL f UL f UL

7 LTE physical layer, 3GPP Downlink: Adaptive OFDM Channel-dependent scheduling and link adaptation in time and frequency domain time frequency Uplink: SC-FDMA with dynamic band width (Pre-coded OFDM) Low PAPR Higher power efficiency Reduced uplink interference ( enables intra-cell orthogonality ) time frequency evolution and Downlink peak datarates MIMO order (Tx/Rx antennas) 4 Evolution >50 Mbps >200 Mbps 2 Evolution >25 Mbps >100 Mbps 1 >4 Mbps 14 Mbps >25 Mbps >50 Mbps Carrier bandwidth (MHz)

8 MIMO for Testbed for evolution MIMO with 2 antennae - 20 Mbit/s over air now working in lab! Demo made at CTIA in April Status testbed DL Up to peak 100 Mbps with 4 multi-streams Application server FTP Web browsing Video/TV streaming BS UL Peak 20 Mbps/user Ue Application client S3G

9 testbed 46 Mbit/s transmitted over air in December 2005 over one 20 MHz channel; full 60 Mbps will be reached after DSP processor upgrade Applications running in downlink in March Implementation of new uplink channel ongoing, peak rate 20 Mbps The new RBS transciever board for 20 Mhz carrier bandwidth modulation (OFDM) Variable bandwidth from 600 khz up to 20 MHz Access technology overview End-user bit rate 100 Mbit/s GPON VDSL2 LTE ( Super 3G ) 10 Mbit/s 1 Mbit/s ADSL2+ ADSL WiMAX + MBMS DVB-H WCDMA / CDMA EV-DO 100 kbit/s GSM / EDGE 10 kbit/s Fixed Mobile Broadcast Application
