The Interference Settings component allows you to choose how interference
is modeled by Overture.
Accessing Interference Settings
You can access the interference settings from the menu option:
This will display the interference settings in the
Properties Window:
Properties
The interference settings component has the following properties:
- Temperature. This controls the amount of
thermal noise present in the network.
- Interference Matrix. This is used extensively
by the
Parameter Planning
components. It has the following properties:
- Demand. This is a reference to the
Density
data source that describes the subscriber density to consider when making the interference
matrix.
- Demand Multiplier. This is the multiplier
to apply to the values from the Demand map.
Setting this to zero will exclude the demand from being considered in the interference
matrix.
- Distance Contribution. Together with the
Distance Contribution Unit Subscriber Distance
property, this controls the contribution to the interference matrix due to distance.
- Distance Contribution Unit Subscriber Distance.
Together with the Distance Contribution property,
this controls the contribution to the interference matrix due to distance. The specified
distance contribution will be added into the interference matrix when two radios
are this far apart.
- Standard Deviation. This is the cumulative
standard deviation of interference analyses. This should be set to reflect the accumulated
error in the prediction algorithms. It controls the spread of interference probabilities
in analyses such as statistics and maps. A special value of 0dB can be used to imply
a hard threshold.
- Target. This is the CINR value that represents
a 50% probability of service.
- Unit Area Contribution. This is the interference
contribution due to the area of coverage overlap between two radios. The total overlapping
area is accumulated and then divided by this figure to calculate the contribution
to the interference matrix for these radios. Setting this figure to zero will prevent
area from contributing to the interference matrix.
- Unit Service Contribution. The data source
specified by the Demand property is accumulated
wherever the coverage of two radios overlap, then the resulting figures are divided
by this value to calculate the contribution to the interference matrix for two overlapping
radios. Setting this figure to zero will prevent the demand from contributing to
the interference matrix.
