Broadcasting (TECH Module)

Broadcasting is a TECH module in the WinRPT, dedicated to design Radio/TV broadcasting systems. Starting from the creation of an antenna system and its technological characterization, Broadcasting allows the analysis of coverage and interference of individual systems and complex networks, analog and digital MFN and SFN networks.

Broadcasting enables the creation of a complete antenna system directly from its graphical representation thanks to the new Editor 3D. Alternatively, Broadcasting offers all those tools which are suitable to import antenna systems stored in the most commonly used formats, very rapidly. The tool is designed so that any operator can easily interface with government agencies: in effect, an antenna system can be imported and exported in the following formats: TA0, TA1, TVA, TVD, TD0, TD1,TD2, TD3. Similarly, thanks to a number of tools provided by the tool, it is possible to analyze the environmental impact of an electric field generated by a Radio/TV transmitter, checking their compliance with applicable laws and sending the resulting documentation directly to the ARPAs (Agenzie Regionali per la Protezione Ambientale - Regional Agencies for Environmental Protection).

There are many technologies currently managed in the tool including: DVB-T, DVB-H, DVB-T2, DVB-T2 Lite, ISDB-T, ISDB-Tb, Onda Media, DRM, DAB, DAB+, PAL, SECAM, NTSC, Radio FM.

Broadcasting has been developed to perform an effective analysis of both simple scenarios and complex ones, with a high number of transmitters. Basic territorial data are provided together with the tool, however Sedicom can provide data of a different kind in order to to allow to simulate the network behavior in various scenarios (using higher resolutions, land use clutters, population clutters, raster cartography, orthophotos).

Broadcasting can be acquired in different configurations according to the user's specific needs:

Different calculation methods allow to simulate the coverage in a specific area or in a customized list of points (or an automatically generated grid of points).

A dedicated interface allows to analyze "PDVs" in accordance with a coordination procedure on domestic and foreign checkpoints reflecting the technical constraints used to create the AGCOM Digital Plan.
When the processing has been completed, an output file is generated; for every line it features the same information of the original PDV, adding two fields to it: total value of interfering CEM and outcome of the comparison with the threshold.

Broadcasting allows to optimize an SFN network, both in terms of coverage and interference, thanks to the precise analysis of contributions relevant to signals received from different transmitters of the SFN network.

Designers are led along the main steps that allow to synchronize the network excellently, as well as to optimize the delay times, so they can minimize the interference or "move" it towards less critical areas. There is also an automatic calculation option which calculates the most convenient delay times assigning them to the different transmitters, allowing to maximize the covered population; moreover, it is aimed at reducing auto-interference.

Adding the population clutter, users can generate very detailed reports to know the percentage of population served by the transmitters involved in the simulation.

Coverage/interference studies and analyses are performed according to the ITU/ETSI Regulations.

Coverage/interference maps can be exported on Google Earth in .kml format.

Through the external WebRPT application, it is also possible to: (i) access the Broadcasting's radio database in query mode, (ii) check the active plants on the map in planning mode, (iii) verify the network status, (iv) query individual antenna systems and display relevant details.

Integrating the additional Measurements module, users can import campaigns of measurements performed using the most common tools, cataloging and sorting the measured points according to date, channel, geographic filter, etc.
