ATTENUATION: Signal Strength Diminishes through Materials

BU

ILD

ING

WA

LL

Wood and plaster Walls or Floors are OK. Even Brick.

Metal and thick rock block the RF signals.

The Higher the Frequency, the more signal loss.

5 GHz is worse than 2.4 GHz.











Designed for Homes:More Absorption, Less Reflection

Signals can arrive at different times and cancel each other out.










Wireless is a New & Emerging Market

• Consumers – Convenience and Mobility:– No Wiring cost or complexity– Existing Devices get New Function & Value– Bundles: Single Bill & Support # and Monthly Savings

• Carriers – Integrated Bundles:– New Revenue Sources (e.g. more phone lines)– Operational Efficiencies (e.g. digital capacity vs. analog)– Revenue Protection (e.g. long distance eroding)– Customer Loyalty and Competitive Barriers

• Individual services become commodities• Limit switching incentives• Bundle or perish
