Radio Mobile -- Free Radio Organizing Software

Radio wave dissemination is a very complex process. It is impossible to exactly predict how dunes will spread along with what values we will evaluate at some particular point. Therefore we incorporate some mathematical models in order to approximate radio reproduction and to calculate industry strength values as outlined by predefined probability.

The actual propagation model, which is based on electromagnetic idea and on statistical evaluation of both landscape features and radio stations measurements, predicts the particular median attenuation of the stereo signal as a aim of distance and the variation of the signal with time and in space. Propagation models define curves and formulas. By using these model we can anticipate propagation in arbitrary distance from the transmitter.

Utilizing curves and statistical formulas manually is definitely a tough task. To be able to automate and accelerate such calculations a lot of software tools were developed. Normally, radio arranging software packages are used by broadcasters, mobile operators as well as radio frequency authorities. As a result of complexity and few potential customers, the price of such software package can be fairly 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 that under the "freeware" license so that the software is readily available on the web. This software is usually dedicated to amateur radio stations, however, it can be furthermore used in other areas which include broadcasting and skilled mobile communications.

Calculations are based on the Longley-Rice reproduction model. This is a common purpose radio dissemination model for frequencies between 20 MHz and 20 Ghz. In order to use the software additionally you need terrain style data. This data is needed for calculations associated with effective heights which can be needed to perform reproduction calculations. You can find some terrain model data sources on the web. They offer free DTM (Digital Terrain Model) data that's enough to start dealing with the Radio Mobile.

Radio Mobile supports numerous fancy features like possibility to use DTM in numerous formats (DTED, SRTM), also in a lot of layers with different resolution, possibility to add guide pictures in raster format (BMP, JPEG, GIF, TIFF, PNG), possibility to calculate interference between the air and lots of functions to customize the view.

Basic strategy for use consists of going into radio stations with all variables (if they are not entered yet) and formula of the coverage. Right here you have a lot of options to customize the calculation and examine. Results can be stored for later use. It is also easy to define calculation action for coarse data to save some time.

Pertaining to result display it will always be not enough to display it on the gray level DTM. You would probably like to see this on some guide. For this purpose you can use just about any map picture along with known coordinates. The program allows you to enter matches for each picture to be able to display it appropriately over the DTM.

A very helpful function is the calculation of interference involving radio stations. You determine protection ratio along with minimum field power for calculation along with the software marks disturbance area with defined color.

The software is additionally very useful for microwave link planning. It enables you to display ground profile between a couple of points, display associated with optical visibility through the point and computation of link details. Although this software is free and dedicated pertaining to amateur radio it is usually very useful tool with regard to daily radio communication tasks.
