Note: System level simulations require estimates of the probability of line-of-sight. The LOS probability models are based on relatively limited data sets and/or specific assumptions and approximations regarding the location of obstacles in the direct path, and should therefore not be considered exact.
In In case the LOS probability is used, the path loss is computed as follows [2]::
for a given Tx-Rx distance d:
- compute probability of LoS:
Mathinline body --uriencoded--
...
P_%7BLOS%7D - draw a sample value from uniform distribution

the path is LoS:Mathinline body --uriencoded--u\ <\ P_%7BLOS%7D
