Detailed Description

The HybridBuildingsPropagationModel is a compound of different models able to evaluate the pathloss from 200 to 2600 MHz, in different environments and with buildings (i.e., indoor and outdoor communications).

This model includes Hata model, COST231, ITU-R P.1411 (short range communications), ITU-R P.1238 (indoor communications), which are combined in order to be able to evaluate the pathloss under different scenarios, in detail:

Environments: urban, suburban, open-areas;
frequency: from 200 uo to 2600 MHz
short range communications vs long range communications
Node position respect to buildings: indoor, outdoor and hybrid (indoor <-> outdoor)
Building penetretation loss
floors, etc...

Warning: This model works only with BuildingsMobilityModel
