3.4 Estimated RF Coverage per RRH
3.4.1 Propagation Model (Free Space Loss)
A simplified model is used to calculate the propagation losses for in- and outdoor
environments.
Free-space propagation conditions are assumed. Obstacles penetrated in direction of
transmission are causing additional RF losses.
Due to relatively short ranges in buildings, line-of-sight conditions can be assumed which are
interrupted by obstacles. Consequently, impact of scattering is neglected. That leads to a
fading model in which the logarithmic normal portion is only to representing shadowing
effects. The Raleigh fading for non-line-of-sight conditions is deliberately ignored to simplify
the model.
The propagation losses are calculated with the formula below:
Losses [dB] = 32.4 + 20 * log10 (Frequency [GHz]) + PC * 10 * log10 (Distance[m])
+ Wall losses [dB] + fading margin [dB]
PC: propagation coefficient
The propagation coefficient PC is dependant on the building itself and has to be adapted in
order to meet the building topology. Estimates of PC are shown in
Table 4.
