# ESD and ESA refer to elevation angle spreads at the indoor and outdoor terminals, respectively.<br />

System level simulations require estimates of the probability of line-of-sight. For scenarios A2, B2,<br />

B4, C2 and C3, the LOS probability is approximated as being zero. For the remaining scenarios, LOS<br />

probability models are provided in Table 4-7. These models are based on relatively limited data sets<br />

and/or specific assumptions and approximations regarding the location of obstacles in the direct path,<br />

and should therefore not be considered exact.<br />

If the terminal locations are known with respect to a street grid or floor plan, which can be the case in<br />

grid-based scenarios such as A1 (indoor) and B1 (urban microcell), the <strong>WINNER</strong> channel model<br />

provides the option to determine the existence of NLOS/LOS propagation conditions<br />

deterministically.<br />
