HSDPA
Ready 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: 3GPP Release 5
-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 ?
• 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
Packet traffic is
increasing rapidly
Network to be prepared
in advance
• “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.

• 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.
