Presentation Transcript

  1. Wireless Data Networking Network Terminology • Macro, Micro, Pico Service Groupings • LAN, WAN, Serial Technologies • EDGE, GPRS, 1XEV, UMTS, 1XEVDO • 802.11, LMDS • IR, Bluetooth

  2. 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

  3. Wireless Data Networking Service Grouping

  4. 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

  5. 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

  6. 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

  7. Wireless Data Networking Pico Technologies • IR • Poor utility • Low Penetration • Proximal line of sight • Bluetooth • RF radiation pattern • Easy to use • Higher speed • Unproven

  8. 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

  9. Wireless Data Networking Conclusions Macro • UMTS • Not commercially available • Predicted to have the largest footprint • 1XEVDO • Excellent data speeds • Questionable global/National footprints

  10. 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
