RES535 – 331 – ANNEX TO RESOLUTION 535 (REV.WRC-15) This Annex responds to the need for information in the application of Article 12; the flowchart in Description 2 provides an overview of the Procedure. 1 Software development The Procedure will require a number of user-friendly software modules to be developed, tested and supplied to administrations by the Bureau. This will ensure that the same software modules are used by administrations and the Bureau for the analysis of the schedules. The Bureau should: – develop the aforementioned software with assistance from administrations; – distribute the software, together with user instructions and relevant documentation; – organize training in the use of the software; – monitor the functional performance of the software and, if required, make necessary modifications. 2 Software modules Data capture of requirements A new module will be required that permits the capture of all data elements detailed in Description 3. This module should also contain validation routines that prevent inconsistent data being captured and sent to the Bureau for processing. Propagation calculation This new module should calculate the field strength and other necessary data at all relevant test points as described in Descriptions 1 and 4. It should also include an option that allows administrations to select the optimum frequency bands for their requirements. The output format of the data and the medium should be such as to allow easy publication and distribution of the results to all administrations. The results of these calculations should be displayable in a graphical format. Compatibility analysis This module should use the output of the propagation calculation to provide a technical analysis of a requirement both alone and in the presence of other requirements as in Description 4. This analysis would be used in the coordination process. The values for the parameters given in Description 4 should be user selectable, but in the absence of other values the recommended default values should be used. The results of this analysis should be capable of being displayed in a graphical format for a defined service area as in Description 4.
