Radio wave reproduction is a very complex course of action. It is impossible to exactly predict how ocean will spread as well as what values we will evaluate at some distinct point. Therefore we possess some mathematical models in order to approximate radio reproduction and to calculate industry strength values based on predefined probability.

The propagation model, which can be based on electromagnetic concept and on statistical evaluation of both ground features and r / c measurements, predicts your median attenuation of the stereo signal as a objective of distance and the variability of the signal with time and in space. Distribution models define shape and formulas. With your model we can anticipate propagation in hit-or-miss distance from the transmitter.

Employing curves and statistical formulas manually is certainly a tough task. As a way to automate and quicken such calculations many software tools were produced. Normally, radio planning software packages are used by broadcasters, mobile operators as well as radio frequency authorities. As a consequence of complexity and few potential customers, the price of such software package can be pretty high. But there is a single exception to this principle.

Radio Mobile is often a software tool for radio propagation calculation. The article author 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 radio, however, it can be also used in other areas which include broadcasting and professional mobile communications.

Computations are based on the Longley-Rice distribution model. This is a basic purpose radio propagation model for frequencies between 20 MHz and 20 Ghz. In order to use the software additionally you need terrain style data. This details are needed for calculations regarding effective heights that are needed to perform dissemination calculations. You can find some terrain model information sources on the web. They offer free DTM (Digital Landscape Model) data which is enough to start working together with the Radio Mobile.

Radio Mobile supports numerous fancy features similar to possibility to use DTM in various formats (DTED, SRTM), also in several layers with different decision, possibility to add guide pictures in raster file format (BMP, JPEG, GIF, TIFF, PNG), possibility to determine interference between r / c and lots of functions to customize the view.

Basic strategy for use consists of coming into radio stations with all details (if they are not moved into yet) and computation of the coverage. Below you have a lot of choices to customize the calculation and examine. Results can be preserved for later use. It is also easy to define calculation step for coarse information to save some time.

Pertaining to result display in most cases not enough to display it on the gray level DTM. You would probably like to see that on some chart. For this purpose you can use any kind of map picture with known coordinates. The software program allows you to enter coordinates for each picture so that you can display it appropriately over the DTM.

A very beneficial function is the computation of interference in between radio stations. You define protection ratio and also minimum field energy for calculation and also the software marks disturbance area with predefined color.

The software can be very useful for micro-wave link planning. It allows you to display surfaces profile between two points, display regarding optical visibility through the point and calculations of link parameters. Although this software is free of charge and dedicated for amateur radio it can be very useful tool regarding daily radio communication tasks.
