Model_DPM

Data Fields

Detailed Description

This structure is used to set the model parameters of the DPM (Dominant Path Model). This structure can be passed optionally to the WinProp_Predict function.

ExponentLOS
double Model_DPM::ExponentLOS
Path loss exponent LOS, allowed range [1, 10]
ExponentOLOS
double Model_DPM::ExponentOLOS
Path loss exponent OLOS, allowed range [1, 10]
ExponentNLOS

ExponentLOSafterBP
double Model_DPM::ExponentLOSafterBP
Path loss exponent LOS after breakpoint (only urban and rural), allowed range [1, 10]
ExponentOLOSafterBP
double Model_DPM::ExponentOLOSafterBP
Path loss exponent OLOS after breakpoint (only urban and rural), allowed range [1, 10]
ExponentNLOSafterBP
double Model_DPM::ExponentNLOSafterBP
Path loss exponent NLOS after breakpoint (only only indoor), allowed range [1, 10]
Waveguiding
int Model_DPM::Waveguiding
Waveguiding, set to 1 to enable, 0 otherwise.
WG_Weighting
double Model_DPM::WG_Weighting
Weighting factor for waveguiding in the range (0,1).See also Waveguiding
WG_MaxDistance
double Model_DPM::WG_MaxDistance
Distance [m] for waveguiding consideration, allowed range [0, 100]See also Waveguiding
AdaptiveResolution
int Model_DPM::AdaptiveResolution
Adaptive resolution factor. A value greater 0 activates the adaptive resolution. Upper limit is 4.
Offset_LOS_Pixels
double Model_DPM::Offset_LOS_Pixels
Offset to be added to all LOS pixels, allowed range [-100, 100]
Offset_NonLOS_Pixels
double Model_DPM::Offset_NonLOS_Pixels
Offset to be added to all Non-LOS pixels, allowed range [-100, 100]
BuildingLossPerMeter
double Model_DPM::BuildingLossPerMeter
Attenuation [dB/m] for path over rooftops, allowed range [0, 10]
BuildingLossDistance
double Model_DPM::BuildingLossDistance
Distance [m] to a roof, a ray needs to travel within to apply BuildingLossPerMeter, allowed range [0.1, 15]
BuildingLossFactor
double Model_DPM::BuildingLossFactor
Factor for switching between more empirical over roof top loss computation and a obstacle within fresnel zone strategy.
  • 0.0 = empirical strategy is being used (based on pixels within BuildingLossDistance over a roof)
  • 1.0 = strategy based on obstacles within a fresnel zone
  • 0.5 = both strategies being equally used
BuildingLossMaxFresnel
double Model_DPM::BuildingLossMaxFresnel
The added loss if an obstacle completely blocks the fresnel zone
ConsiderFloorsBuildings
unsigned char Model_DPM::ConsiderFloorsBuildings
Boolean to use floors in buildings, set to 1 to enable, 0 otherwise. Only relevant for indoor scenarios not required for urban scenarios.
ConsiderFloorsTrxBuilding
unsigned char Model_DPM::ConsiderFloorsTrxBuilding
Boolean to use floors in building with Tx, set to 1 to enable, 0 otherwise. Only relevant for indoor scenarios not required for urban scenarios.
PathSearchSameSettings
unsigned char Model_DPM::PathSearchSameSettings
Set to 1 to consider the set exponents and the set diffraction loss also for the DPM path search.
AdditionalHeight
double Model_DPM::AdditionalHeight
Additional height for pixels within topography in case of prediction on absolute height. Needed to get path traveling across the topography, pixels will not be contained in the results (as they're within the topography). Needs to be larger than zero.
AdditionalHeightBuildings
double Model_DPM::AdditionalHeightBuildings
Additional height for pixels within buildings. Needed to get paths traveling across buildings. If WinProp_ParaMain::BuildingsIndoorCoverage is set to COVERAGEINDOOR_ONROOF, the pixels will be contained in the result. Needs to be larger than zero.
IndoorExponentsSameAsUrban
unsigned char Model_DPM::IndoorExponentsSameAsUrban
Boolean to use the urban exponents also for indoor prediction in CNP Hybrid Urban/Indoor (CNP) projects, set to 1 to enable, 0 otherwise. Only relevant for Hybrid Urban/Indoor (CNP) projects, not required indoor scenarios.
