Radio wave dissemination is a very complex method. It is impossible to exactly predict how surf will spread along with what values we will calculate at some distinct point. Therefore we incorporate some mathematical models for you to approximate radio distribution and to calculate field strength values in accordance with predefined probability.

Your propagation model, that's based on electromagnetic theory and on statistical analysis of both surfaces features and radio measurements, predicts the particular median attenuation of the radio stations signal as a function of distance and the variability of the signal with time and in space. Dissemination models define curves and formulas. Basic model we can anticipate propagation in irrelavent distance from the transmitter.

Employing curves and precise formulas manually is definitely a tough task. So that you can automate and quicken such calculations many software tools were developed. Normally, radio organizing software packages are used by tv stations, mobile operators and radio frequency authorities. As a consequence of complexity and few potential customers, the price of this kind of software package can be pretty high. But there is one exception to this tip.

Radio Mobile can be a software tool for r / c propagation calculation. The article author has decided to publish it under the "freeware" license which means that the software is unhampered available on the web. This software is usually dedicated to amateur stereo, however, it can be also used in other areas including broadcasting and specialist mobile communications.

Information are based on the Longley-Rice dissemination model. This is a general purpose radio distribution model for wavelengths between 20 Megahertz and 20 Ghz. In order to use the software you also need terrain style data. This details are needed for calculations associated with effective heights which can be needed to perform reproduction calculations. You can find a number of terrain model info sources on the web. They feature free DTM (Digital Landscape Model) data that is enough to start working with the Radio Mobile.

Radio Mobile supports a lot of fancy features like possibility to use DTM in several formats (DTED, SRTM), also in many layers with different quality, possibility to add map pictures in raster file format (BMP, JPEG, GIF, TIFF, PNG), possibility to compute interference between radio stations and lots of functions a customized view.

Basic method of use consists of getting into radio stations with all details (if they are not came into yet) and computation of the coverage. The following you have a lot of choices to customize the calculation and consider. Results can be rescued for later use. It is also very easy to define calculation action for coarse calculations to save some time.

For result display it is almost always not enough to display this on the gray scale DTM. You would probably like to see it 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 in order to display it effectively over the DTM.

A very beneficial function is the calculations of interference between radio stations. You define protection ratio and minimum field energy for calculation along with the software marks interference area with definite color.

The software can be very useful for microwave link planning. It helps you to display ground profile between two points, display associated with optical visibility from any point and calculation of link variables. Although this software is totally free and dedicated for amateur radio it is usually very useful tool regarding daily radio interaction tasks.
