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

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

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
