Frequency Assignment and Licensing
Frequency arrangement options
General procedure for the frequency assignment and licensing process
Registration of the application in the administrative database and initialization of the workflow management
The request is not accepted for an ADM reason.
Folder processing. Transmission to administrative and technical studies
The frequency is not available because it is protected by ITU agreement.
Verification of international coordination requirements
The folder is transmitted to coordination study and ITU sending.
Notifications forms generation and registration in ITU database
License and invoice sending.
License and invoice emission
The folder is transmitted for license issuing and invoice generation. The relevant documents are provided to the spectrum user.
The folder is closed and archived. The licensing process is over.

Coordination & Notification
Annex I : Action Plan (rev.2) for development of SMS4DC
1 Provisional test for items listed in Annex II & III.
2 Software developers would try to make the space segment ready for provisional acceptance test.
Note: French version of SMS4DC will be ready before WTDC-06 and the other 4 languages if required by the end of 2006.

Draw Line from Database
Draw Box from Database
Toggle button to create rubber-band box for selection of a rectangular area on DEM to activate area dependent functions.
Push button for deactivation of activated buttons. The shape of mouse is changed to normal by using this button.
Push buttons for navigation of DEM one tile toward one of the West, North, South and East directions each time, respectively.
Toggle button to draw line between two points and to activate functions based on predefined line.
Toggle button for poly line drawing and activation of relevant functions based on predefined poly line.
Push button for drawing a line between two stations and for activation of functions based on predefined line, using database of stations.
Push button to refresh screen display and to remove overlaid area-calculation results from DEM.
Push button for drawing a square box containing a station at its middle for activation of functions based on predefined area, using database of stations. .
Push button to overlay area-calculation results on DEM. Once an area selected on map (using box drawing buttons) this button will be activated.
Toggle button to move a station to a new location using mouse. Click mouse right button on the station and drag its symbol to the concerned location while holding mouse right click.
Toggle button to add a station under one of the SMS4DC supported services.
Push button for drawing of path profile along depicted line. Poly line drawing does not activate this button.
Toggle button to show or remove legend of activated display. An appropriate legend is displayed depending to the activated display, i.e. DEM color legend for DEM view, field strength color legend for area calculation result window and etc.

Effective height of an antenna can be calculated based on ITU-R Recommendations
P.1546 or P.370. This parameter is needed for Field strength calculations
in point to area services (i.e. Broadcasting, land-mobile…).
