Wireless data networking1

Wireless Data Networking

  • Network Terminology

    • Macro – Wan

      • Typically city sized

      • Sprint, AT&T, Cinguler…

    • Micro – LAN

      • Office size

      • Privately owned

    • Pico – Serial Cable

      • Device sharing

      • Autonomous networks

Service Grouping


Wireless data networking3

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 networking4

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 networking5

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 networking6

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 networking7

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


Wireless data networking8

Wireless Data Networking

Conclusions Macro

  • UMTS

    • Not commercially available

    • Predicted to have the largest footprint

  • 1XEVDO

    • Excellent data speeds

    • Questionable global/National footprints


Wireless data networking9

Wireless Data Networking

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
