require

estimates

of

the

probability

of

line-of-sight.

The

are

based

on

relatively

limited

data

sets

specific

assumptions

and

approximations

regarding

the

location

of

obstacles

in

the

direct
...
path,
...
and

should

therefore

not

be

considered

exact.

In case the LOS probability is used, the path loss is computed as follows [2]:
