Tracks of B3G Evolution
IMT-2000 enhancement
HSDPA deploy in 2005 for the evolution of WCDMA
High Speed WLAN
WRC-2003 has assigned 455MHz B/W in 5GHz band for
WLAN service
Portable Internet
Public portable Internet service deploy
using currently assigned commercial mobile
service B/W
New Mobile Access /4G
WRC-2007 is supposed to specify the frequency
bandwidth system requirement for 4th generation
mobile communication system

Internet Service Evolution

• Typical Internet Services
• High-speed Wireline Internet Services (Cable
  Modem / ADSL / VDSL)
• IP service in a home domain
• 1 10Mbps(upgraded to 50Mbps)
• Medium or Low Speed Wireless Internet Services
  (Cdma2000, WCDMA)
• Cellular-based platform originating/termination
  call
• Public mobile service, but expensive
• 144/384 Kbps (1x, wcdma), 2.4/10Mbps (Ev-DO,
  HSDPA)
• High-speed Wireless Internet Service(IEEE 802.11
  series, Private Services)
• IP service in a local or private area
• Maximum 54Mbps
• Demand on a High-speed Portable Internet (PI)
  Service
• High-speed data, Low-cost, Portable(Low-mobility)
  Service
• Easy service connectivity.
• Wireline and wireless network convergence.
• Multimedia services.

PI Service Class

• Interactive Service Best-efforts
• Web Browsing, Interactive Game, etc.
• Streaming service(rtPS Real Time Poling
  Service)
• VoD, MPEG, etc.
• Back Ground service(nrtPS Non Real Time Poling
  Service)
• FTP, E-MAIL, SMS, multicast/broadcast, MMS, Push
  etc.
• Real Time Service(UGS Unsolicited Grant
  Service)
• VoIP

PI System Requirement

• Lower service cost
• Maximize cell average throughput
• Maximize number of active users
• High-speed data transmission
• 2Mbps per users for multimedia services
• Maximize modulation efficiency 50Mbps / 10MHz
• Higher service quality
• Seamless access
• Full coverage handover
• Accommodate multimedia traffic
• Connection oriented, bandwidth allocation
• Accommodate high burst traffic
• Dynamic bandwidth allocation mechanism
• Security
• Authentication, ciphering
