Hsdpa ready for commercial service within one year l.jpg
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

What is happening in current mobile market in japan l.jpg
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.

Mimo multiple input multiple output l.jpg
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

Down link access scheme ofdm l.jpg
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

Evolution of Radio Access Network- Flow of 2 Systems Aiming at Wireless Broadband -

  • Multiple new wireless technologies with high-speed, wide-band, and high mobility emerged aiming at Beyond 3G

  • Two systems (1) “Cellular phone technology” based on 3G or 3.5G and (2) “Wireless LAN technology” based on _WiFi are present and various kinds of regulations appeared.
