Wireless Data Networking

Macro Technologies

  • EDGE
    • Spectrally inefficient
    • Med-High usage charge
    • Low Data Speeds (25Kbps)
    • Poor Security
  • GPRS
    • Better spectrum use
    • Lower usage charge
    • Better Data Speeds (35 Kbps)
    • Better but still poor security
  • 1XEV
    • Very good spectrum efficiency
    • Lowest usage charge
    • High data rates (64 – 300 Kbps)
    • Perfect security

Wireless Data Networking

Macro Technologies

  • UMTS
    • Spectrally efficient
    • Med-low usage cost
    • High data speeds ( 80 Kbps - 1.1 Mbps)
    • Perfect Security
  • 1XEVDO
    • Highest spectral efficiency
    • Low usage cost
    • Highest data speeds (2.4 Mbps)
    • Perfect security

Wireless Data Networking

Micro Technologies

  • 802.11
    • Dominant technology
    • Ethernet add on
    • High data speeds ( 11 Mbps)
    • Security Concerns
  • LMDS
    • Questionable penetration
    • Service provider add on
    • Medium speed (3 Mbps)
    • Better security

Wireless Data Networking

Pico Technologies

  • IR
    • Poor utility
    • Low Penetration
    • Proximal line of sight
  • Bluetooth
    • RF radiation pattern
    • Easy to use
    • Higher speed
    • Unproven

Wireless Data Networking

Conclusions Macro

  • EDGE
    • Will be phased out 3-5 years
    • Low utility
  • GPRS
    • Huge footprint, longer phase out period
    • Low utility
  • 1XEV
    • Small but growing footprint
    • Growing technology

Conclusions Macro

  • UMTS
    • Not commercially available
    • Predicted to have the largest footprint
  • 1XEVDO
    • Excellent data speeds
    • Questionable global/National footprints

Conclusions Micro

  • 802.11
    • Dominant technology
    • Installation not per usage costs
  • LMDS
    • Questionable market penetration
    • Low installation but per usage charges

Conclusions Pico

  • IR
    • Poor utility
    • Being phased out
  • LMDS
    • Good utility
    • Unproven technology
