Radio wave reproduction is a very complex procedure. It is impossible to precisely predict how waves will spread along with what values we will measure at some particular point. Therefore we have some mathematical models to be able to approximate radio reproduction and to calculate discipline strength values in accordance with predefined probability.

Your propagation model, which is based on electromagnetic idea and on statistical analysis of both ground features and stereo measurements, predicts the actual median attenuation of the stereo signal as a function of distance and the variation of the signal in time and in space. Dissemination models define figure and formulas. With your model we can forecast propagation in haphazard distance from the transmitter.

Utilizing curves and precise formulas manually is certainly a tough task. As a way to automate and accelerate such calculations a lot of software tools were created. Normally, radio preparing software packages are used by tv producers, mobile operators along with radio frequency authorities. As a consequence of complexity and few potential customers, the price of these kinds of software package can be rather high. But there is a single exception to this principle.

Radio Mobile is really a software tool for radio propagation calculation. Mcdougal has decided to publish this under the "freeware" license meaning that the software is readily available on the web. This software is usually dedicated to amateur r / c, however, it can be furthermore used in other areas such as broadcasting and expert mobile communications.

Information are based on the Longley-Rice distribution model. This is a common purpose radio dissemination model for frequencies between 20 Megahertz and 20 Ghz. In order to use the software in addition, you need terrain product data. This details are needed for calculations of effective heights which are needed to perform dissemination calculations. You can find a number of terrain model info sources on the web. They provide free DTM (Digital Ground Model) data that is enough to start working together with the Radio Mobile.

Radio stations Mobile supports many fancy features like possibility to use DTM in a variety of formats (DTED, SRTM), also in numerous layers with different resolution, possibility to add chart pictures in raster formatting (BMP, JPEG, GIF, TIFF, PNG), possibility to estimate interference between radio stations and lots of functions a customized view.

Basic strategy for use consists of entering radio stations with all parameters (if they are not came into yet) and calculations of the coverage. Below you have a lot of choices to customize the calculation and view. Results can be preserved for later use. It is also simple to define calculation stage for coarse computations to save some time.

Pertaining to result display it is usually not enough to display this on the gray range DTM. You would probably like to see the idea on some chart. For this purpose you can use just about any map picture using known coordinates. The application allows you to enter harmonizes for each picture as a way to display it appropriately over the DTM.

A very useful function is the calculations of interference involving radio stations. You establish protection ratio and also minimum field strength for calculation along with the software marks interference area with defined color.

The software can also be very useful for micro wave link planning. It helps you to display ground profile between 2 points, display associated with optical visibility through the point and formula of link details. Although this software is free and dedicated pertaining to amateur radio it is usually very useful tool pertaining to daily radio communication tasks.
