The Mobility Settings component allows you to choose how mobility is modeled by Overture. It is based around a Mobility Matrix, which stores the potential cost of a handoff occurring between every pair radios in the network.

Accessing Mobility Settings

You can access the mobility settings from the Analysis > Settings > Mobility menu option:

This will display the mobility settings in the Properties Window:

Properties

The mobility settings component has the following properties:

• Access Model. This is a reference to the Cover Model that specifies the probability of coverage at each point.
• Demand. This is a reference to the Density data source that describes the subscriber density to consider when making the mobility 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 mobility matrix.
• Distance Contribution. Together with the Distance Contribution Unit Subscriber Distance property, this controls the contribution to the mobility matrix due to distance.
• Distance Contribution Unit Subscriber Distance. Together with the Distance Contribution property, this controls the contribution to the mobility matrix due to distance. The specified distance contribution will be added into the mobility matrix when two radios are this far apart.
• Reporting Depth. This controls how many servers are considered when generating the Mobility Report.
• Terminal. This is a reference to the Terminal that specifies the type of equipment.
• Unit Area Contribution. This is the mobility 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 mobility matrix for these radios. Setting this figure to zero will prevent area from contributing to the mobility 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 mobility matrix for two overlapping radios. Setting this figure to zero will prevent the demand from contributing to the mobility matrix.

Actions

The mobility settings component has the following actions:

• Mobility Report. This generates a Table with one row per radio. The number of columns in table is controlled by the Reporting Depth property. The columns display the radios with the highest entries in the mobility matrix for each row.
