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 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 Macro Technologies

5. Wireless Data Networking 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 Macro Technologies

6. Wireless Data Networking 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 Micro Technologies

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

8. Wireless Data Networking 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

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

10. Wireless Data Networking 802.11 Dominant technology Installation not per usage costs LMDS Questionable market penetration Low installation but per usage charges Conclusions Micro Conclusions Pico IR Poor utility Being phased out LMDS Good utility Unproven technology
