    33  *  \brief The Okumura Hata (OH)-Building-Propagation-Model is propagation module

    34  *  using only the Okumura Hata model from the one provided by

    35  *   BuildingsPropagationLossModel, in different environments and with 

    36  *   buildings (i.e., indoor and outdoor communications).

    37  *

    38  *  This model includes Hata model, COST231, ITU-R P.1411 (short range

    39  *  communications), ITU-R P.1238 (indoor communications). 

    40  *  Building-Propagation-Model properly combines the models above in order

    41  *  to be able to evaluate the pathloss under different scenarios, in detail:

    42  *  - Environments: urban, suburban, open-areas;

    43  *  - frequency: from 200 uo to 2600 MHz

    44  *  - short range communications vs long range communications

    45  *  - Node position respect to buildings: indoor, outdoor and hybrid (indoor <-> outdoor)

    46  *  - Building penetretation loss

    47  *  - floors, etc...

    48  *

    49  *  Frequency: 200 MHz to 2000 MHz

    50  *  Link Distance:up to 20 km

    51  *  \warning This model works with BuildingsMobilityModel
