    • 10. HSDPA Ready for commercial service within one year Near to Base station ( High Radio Strength) Far from Base Station (Low Radio Strength)
      • Adaptive Modulation and Coding
      • QPSK to 16QAM, Low to High Error Correction
      • - Hybrid ARQ, Fast Adaptive Scheduling
      • Down link : W-CDMA=384kbps  HSDPA=14.4Mbps
      • Improvement of total throughput with dynamic far field / near field control
      • HSDPA specification: 3GPP   Release 5
      Low Speed High Speed HSDPA uses remaining carrier power for packet traffic Packet Traffic
    • 11. What is happening in current mobile market in Japan ?
      • 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 Packet traffic is increasing rapidly Over 100 systems are in commercial operation
