Chapter Thirty Five Objectives
  • Explain how third-generation (3G) wireless will
    change the course of hand-held communications
  • Describe the motivations to move toward 3G
  • List and describe features and functions of 3G
    wireless
  • Explain the pieces that make up the new wireless
    data network
  • Describe the concept of the data transition to
    wireless

3
3G Wireless Standards
  • Emerging standards on wireless carrier
  • WAP (Wireless Application Protocol)
  • WML (Wireless Markup Language)
  • Compatibility issues with deployment
  • GSM, TDMA, CDMA
  • Demands on systems
  • International, local, and roaming
  • Various integration schemes

4
3G Wireless Competition
  • User perspectives
  • Coverage areas, pricing plans
  • Cost of implementing, roaming charges
  • Ease of use, long-term usage, battery life
  • Provider perspectives
  • Who has best technology?
  • Stopgap measures dual or tri-mode phones
  • Replacement of analog networks with digital

5
3G Wireless Evolution
  • Wireless standards 1G to 3G

6
3G Wireless Data Transmission
  • Better, faster, cheaper
  • Migrate circuit-switched to packet

7
3G Wireless All Roads Lead to UMTS
8
3G Wireless All Roads Lead to CDMA
  • HSCSD _at_ 19.6 to 64 Kbps in CDMA architecture
  • cdmaOne networks
  • IS-95 air interface (TIA 1993) and ANSI-41
    network protocol, soft handoffs
  • One or more 1.25 MHz carriers, 800- and 1,900-MHz
    frequency bands
  • Max advantages of CDMA digital wireless
  • Incorporate efficiencies of IP
  • IS-95B for hard-handoff in multicarrier
    environments

9
3G Wireless Phases of CDMA Data
  • cdma2000 3X (IS-2000-A)
  • Existing spectrum allocations
  • Twice the voice capacity of cdmaOne
  • Data rates to 144 Kbps
  • Backward compatible with cdmaOne networks and
    terminals
  • Enhances performance
  • IS-2000-A/cdma2000 3X
  • Uses 3 time 1.25 MHz or 3.75 MHz
  • Multicarrier approach, or wide-band cdmaOne
  • Greater capacity than 1X
  • Data rates up to 2 Mbps
  • Backward-compatible with 1X and cdmaOne
  • Enhances performance even more
