Both the distance <strong>and</strong> line of sight (LOS) directi<strong>on</strong> informati<strong>on</strong> of the radio <strong>link</strong>s are calculated for the<br />
input of the model. Distance between the BS i <strong>and</strong> MS k is<br />

Pairing matrix A is in the example case of Figure 6.2 a 3x6 matrix with values {0,1}. Value 0 st<strong>and</strong>s for<br />
<strong>link</strong> MSm to celln is not modelled <strong>and</strong> value 1 for <strong>link</strong> is modelled.<br />
