Communications

This selection brings up a window with a list of communication elements:

Create Link

Selection causes the Communications Definition Form to appear, initially devoid of data.  The normal approach to defining a communications link (or route) is as follows:

  1. The user selects a source for the communications.  He does this using the top half of the interface to pick an asset from either the map or a list.  Details for using this interface are found here.
  2. The user selects the communications suite to be used for transmission from the "Xmit" line.  If you hit the button and an empty list appears, there are no communications suites on this platform type.  Go back to Database Prototyping and add a communications suite to the platform before proceeding.
  3. Verify the 1- versus 2-way communications  and the Data Division options are set correctly.
  4. When the transmission communications suite was selected another asset column appeared on the interface (Example).  This is the next destination.  This can proceed indefinitely (here is an example with three elements to get information from a B-52 to Offut).  In JFORCES descriptions the connection between any two adjacent assets is referred to as a "Link" and the entire communications approach is a "Route".
  5. When done the user saves the data - NOTE: the interim steps are not saved in the database, so nothing is saved until the user chooses to Save.

The user has some other options, for example he can choose to reuse a previously defined communications link from any asset by selecting the "Review Existing Links" from this interface and double-clicking on any selection.  If this window is empty there are no predefined links for this asset so a new one will need to be created.

Delete Link

The links defined either in the above "Create Link" option or the "Create Star" option can be deleted through this interface.  Choosing this option causes the Communications Reduction Form to appear.  All links are presented along with the:

Each may be deleted by clicking on Delete Selections.

Create Star

This is a quick way to generate a number of similar links from a selected asset.  Selection causes the Define Communications Star Form to appear.  The user needs to:


Define Bands

This interface permits users to specify communications bands and their maximum utilization.  If these bands are not defined communications between two assets is limited only by the communications link capacity linking them.  With these bands communications can be limited by theater (and non military) uses.  In addition, these bands provide a framework for analyzing the communications capabilities of the entire system. This choice presents the Define Comm Bands Form to the user along with all Currently Defined Comm Bands.  Each Band is listed by:

All data listed may be changed or deleted.

New Bands may also be created by selecting the Add button.  When selected, the Define Comm Bands Form appears. 

Define Default Loadings

This selection presents the Default Comm Loadings Form that lists the % Bandwidth Available for Scenario.  In this example, the  are three types of communications listed (VHF_SINGARS,HF,UHF) but when you use it the named bands might be different because they are the bands defined above.The available bandwidth for military operations in each of these Comm Bands may be set/reset via a sliding scale bar in place for each.  These values represent the percent of the total bandwidth (defined in the "Define Bands" interface, above) available for scenario use.  In addition default scenario loadings by assets is defined within this interface on the next two lines.  These loadings are:

  1. Typical non-ISR Comm traffic Per Radio Precombat
  2. Typical non-ISR Comm traffic Per Radio In Combat
Both of these are measured in bits per seconds and are used for default band loading.   The reason the communications are limited to non-ISR is the ISR loading comes from the JFORCES sensor model.  If you believe there are additional ISR loadings that JFORCES is not addressing, increase these two values accordingly.
