  1. Prospects for 3G Mobile Communications Market and Technology • 1. 3G Mobile Market Status • 2. View on Future Evolution • A) Radio Aspect • B) Network Aspect • 3. NEC’s Activities January, 2004 NEC Corporation

  2. 1. 3G Mobile Market Status

  3. 90% of mobile users use Mobile Internet in Japan • Mobile users in Japan • Total Mobile users: 85M • Total Mobile internet users :74M • Ratio of 3G user : 30% 3rd Stage Mobile Internet Introduction of new servicesenabled by “fixed rate billing” (as of end Dec 04) (K) 2nd Stage Mobile Internet Photo mail supporting the improvement of Data ARPU 1st Stage Mobile Internet Rapid increase in Mobile Internet users Fixed Rate Billing start (Nov 03) Photo mail start (Nov 00) i-mode start (Feb 99) 1996 1997 1998 1999 2002 2003 2004 2000 2001 Source: TCA (Telecommunications Carriers Association) © NEC Corporation 2004 Confidential

  4. New Revenue generated by Mobile Internet Service Decline in voice service revenue has been recovered by data service revenue. (e.g. NTT DoCoMo) Euro = 135 J-yen Source: NTT DoCoMo © NEC Corporation 2004 Confidential

  9. Flat-rate Charge Service started in Japan Japanese users enjoy rich data service since introduction of flat-rate charge Packet Traffic “Chaku-Uta Full” by au Download entire Music “EZ Channel” by au Periodic auto-delivery Contents service Interactive Game Download contents at night Enjoy contents at anytime and anywhere Set favorite contents (3 programs, max.3MB/prog) © NEC Corporation 2004 Confidential

  10. HSDPAReady for commercial service within one year • Down link : W-CDMA=384kbps  HSDPA=14.4Mbps • Improvement of total throughput with dynamic far field / near field control • HSDPA specification: 3GPPRelease 5 Low Speed • Adaptive Modulation and Coding • QPSK to 16QAM, Low to High Error Correction • - Hybrid ARQ, Fast Adaptive Scheduling High Speed Far from Base Station (Low Radio Strength) Near to Base station (High Radio Strength) Packet Traffic HSDPA uses remaining carrier power for packet traffic © NEC Corporation 2004 Confidential

  11. What is happening in current mobile market in Japan ? Packet traffic is increasing rapidly • Fixed Tariff for Packet traffic is becoming dominant in 3G • AU (Ev-Do): 1 Mil users now • Packet usage 30 times of ordinary users • DoCoMo (WCDMA): 1.4mil user now • Packet usage 13 times of ordinary users • Traffic on 3G network increased 1.9 times • VDF KK (WCDMA): Stared in Nov.2004 • “HSDPA” will be soon. • HSDPA is the key technology for realizing flat-rate packet communication service efficiently. • Best effort type packet traffic increases rapidly by efficient use of radio resources. Network to be prepared in advance Over 100 systems are in commercial operation © NEC Corporation 2004 Confidential

  16. MIMO: Multiple Input Multiple Output Parallel Spatial transmission by multiple transmit and receive antennas increase the Frequency efficiency ■MIMO Multiplexing Parallel spatial Transmission of data signals using Multiple Transmit antennas => Increase Data rate by the number of antennas ■MIMO Diversity Transmit same data and receive them diversity combining => Improve receive performance under bad radio propagating condition Rx Tx #1 #1 #2 #2 #3 #3 #4 #4 Signal Separation & Diversity Combining Parallel Transmission © NEC Corporation 2004 Confidential

  17. Down Link Access Scheme: OFDM VSF-OFCDM • OFCDM: Orthogonal Frequency & Code Division Multiplexing • Optimal Mixture of Orthogonal Frequency Division Multiplexing (OFDM)and Code Division Multiplexing (CDM) • Time and Frequency domain spreading is adopted to OFDM • Improve frequency reuse efficiency by OFDM • Frequency Diversity effect by narrow band multi-carrier • VSF: Variable Spreading Factor • Cellular Environment: Spreading factor > 1 • To reduce the affect of interference • Data Rate: 10Mbps@10MHz BW • Hot spot Environment: Spreading factor = 1 • To increase the link capacity • Data Rate: 100Mbps@10MHz BW with MIMO OFCDM Coding © NEC Corporation 2004 Confidential
