This command is DEPRECATED and has been replaced by:

RFEnvironment

Description

The Environment command allows you to specify the value(s) of specific environmental models as pointed to by a specific attribute. The environmental models include models for rain fade and gaseous absorption.

The Environment commands are applied at the scenario level.

Parameter	Description
<AttributePath>	Specify the path the attribute being changed.
<Value>	The specified attribute will be set to this value.
<Unit>	When entering a numeric value include the <Unit> to specify the abbreviation of the unit that the numeric value is being entered in. If not included then the <Value> is assumed to be in the internal units.

Use this command in conjunction with the Environment_RM GetValue command, which will return a list of attributes, or the properties and choices for a specific attribute.

Examples

Set the UseCloudFogModel attribute to true, and set the ceiling, water density and temperature:

RFEnvironment * SetValue PropagationChannel.UseCloudFogModel true RFEnvironment * SetValue PropagationChannel.CloudFogModel.CloudCeiling 8000 RFEnvironment * SetValue PropagationChannel.CloudFogModel.CloudLiqWaterDensity 456.0 kg/km^3 RFEnvironment * SetValue PropagationChannel.CloudFogModel.CloudTemp 273.15 K

Examples

To set the rain model and rain outage attributes.

First use the Environment_RM GetValue command with the Choices option on the PropagationChannel.RainModel to get the names of valid Rain Models:

Environment_RM * GetValue PropagationChannel.RainModel:Choices

Crane_1985 ITU-R_P618-10 Script_Plugin CCIR_1983 Crane_1982 ITU-R_P618-5 ITU-R_P618-8 ITU-R_P618-9

Set the rain model and rain outage attributes:

Environment * SetValue PropagationChannel.UseRainModel true Environment * SetValue PropagationChannel.RainModel ITU-R_P618-5 Environment * SetValue PropagationChannel.RainModel.SurfaceTemperature 78.6 degC Environment * SetValue RainOutagePercent 0.03

Examples

Enable the Urban Model, load a shapefile, and set options:

The values permissible for setting PropagationChannel.UrbanTerresPropLossModel.BuildingHeightAttribute depend on the content of the shapefile specified by the PropagationChannel.UrbanTerresPropLossModel.UrbanGeometryFile. When defining these attributes it is best to set any other attributes first, then set the UrbanGeometryFile attribute and then the BuildingHeightAttribute.
