Inicio  Anterior  Siguiente


Xirio allows calculations of radio studies both free and pay. It is necessary that the user knows limitations that free simulations to low resolution involve to be able to decide what type fits better to his needs.

Free Estimates have limitations on resolution at which calculation would be performed and on number of cartography layers that could be used. Also, free calculations will remain in your user account only a week and they will not be able to be published to other users.

When the users add cartography layers to their studies the application will advise of minimum calculation resolution that will be available. This value can vary considerably from one layer to another according to cartography provider and information quality. In the following image it is possible to observe a comparison of results obtained for the same coverage, at resolutions of 100 m and 600 m (free).




Whereas the free calculation is adequate for a calculation first approximation, the result provided is not valid from a professional point of view. It is convenient to adjust the study by means of free calculations and then proceed to perform a pay calculation which will provide higher quality and precision results.

To see that with detail, an enlargement of previous coveragen result has been taken. As you can see, the resulting free calculation assumes that much of town in the image is covered, whereas in the calculation in greater detail we can see that it is not.




In the following image it is possible to see a comparison of results obtained for the same urban contour profile calculated at resolutions of 1 m and 6 m (free).




The buildings no longer are distinguished clearly, going so far as even to disappear any of them. In the image it is possible to appreciate that three buildings that obstruct the line of sight at high resolution do not do it at low resolution. However, as in the coverage, it may be interesting to fit simulation by means of free calculations and then to realize a definitive pay calculation.

When performing a pay calculation in Xirio, the user is also entitled to:

The storage of the results of the above mentioned calculation for one month on the Xirio platform.This period of time is extendable by an increase in price.

The possibility of downloading results to the user's computer.

The possibility of sharing the results within a maximum of 10 users by publishing them.

The final cost of a pay calculation will be the sum of the study cost, the increase due to the cartography used and an optional cost for extending the storage period of results.
