Outline
Spring 2006 CS 649 2
· (Simple) Radio Power loss models
· Reality
· (More) Radio Power loss models
Motivation
Spring 2006 CS 649 3
· Communication between nodes over wireless channel
· Characteristics of wireless channel have impact on all
upper layer protocols
· Transmission range
· Loss rate (BER is determined by SNR at the receiver)
· Would like to model those characteristics
· Guide design of future systems
