'''Young model''' is a [[radio propagation model]] that was built on the data collected on [[New York City]]. It typically models the behaviour of [[cellular communication]] systems in large cities.<br />
<br />
==Applicable to/under conditions==<br />
This model is ideal for modeling the behaviour of cellular communications in large cities with tall structures.<br />
<br />
==Coverage==<br />
[[Frequency]]: 150&nbsp;MHz to 3700&nbsp;MHz<br />
<br />
==History==<br />
Young model was built on the data of 1952 in [[New York City]].<br />
<br />
==Mathematical formulation==<br />
The mathematical formulation for Young model is:<br />
<br />
<math>L \; = \; G_B \; G_M \; \left (\frac{h_B \; h_M}{d^2} \right )^2\beta</math><br />
<br />
Where,<br />
:''L'' = [[path loss]]. Unit: [[decibel]] (dB)<br />
:''G''<sub>B</sub> = [[gain]] of base transmitter. Unit: decibel (dB)<br />
:''G''<sub>M</sub> = [[gain]] of mobile transmitter. Unit: decibel (dB)<br />
:''h''<sub>B</sub> = height of [[base station]] antenna. Unit: [[meter]] (m)<br />
:''h''<sub>M</sub> = height of [[mobile station]] antenna. Unit: meter (m)<br />
:''d'' = link distance. Unit: [[kilometer]] (km)<br />
:<math>\beta</math> = [[clutter factor]]<br />
