<strong>Fi</strong>gure 2.14: The Fresnel Z<strong>on</strong>e [49].<br />
The impact <str<strong>on</strong>g>of</str<strong>on</strong>g> power management <strong>on</strong> WLAN throughput was addressed in [17]. Power<br />
management is an efficient way to extend battery life. However, it results in low<br />
throughput <str<strong>on</strong>g>of</str<strong>on</strong>g> WLAN due to lower transmissi<strong>on</strong> power. Enabling power management<br />
functi<strong>on</strong> will decrease performance <str<strong>on</strong>g>of</str<strong>on</strong>g> WLAN around 240%. The study gives us an<br />
insight into power management c<strong>on</strong>trol during propagati<strong>on</strong> measurement.<br />
The highest data rate would have maximum network throughput. RSS and frame error<br />
rate are key factors to determine <str<strong>on</strong>g>the</str<strong>on</strong>g> exact data rate [50, 51]. Poor signal strength not<br />
<strong>on</strong>ly leads to lower throughput, but also small range <str<strong>on</strong>g>of</str<strong>on</strong>g> signal coverage. RSS is an<br />
important benchmark for assessing <str<strong>on</strong>g>the</str<strong>on</strong>g> performance <str<strong>on</strong>g>of</str<strong>on</strong>g> WLANs.<br />
To sum up, <str<strong>on</strong>g>the</str<strong>on</strong>g> studies give us an insight into experimental measurement design and<br />
c<strong>on</strong>sidering interfering factors. The studies also have an important implicati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g><br />
